                     throws XMPException

Description copied from interface: XMPMeta

Simplifies the construction of an array by not requiring that you pre-create an empty array. The array that is assigned is created automatically if it does not yet exist. Each call to appendArrayItem() appends an item to the array. The corresponding parameters have the same use as setArrayItem(). The arrayOptions parameter is used to specify what kind of array. If the array exists, it must have the specified form.

Specified by:

appendArrayItem in interface XMPMeta

Parameters:

schemaNS - The namespace URI for the array. Has the same usage as in getProperty.

arrayName - The name of the array. May be a general path expression, must not be null or the empty string. Has the same namespace prefix usage as propPath in getProperty.

arrayOptions - Option flags describing the array form. The only valid options are

• PropertyOptions.ARRAY,
• PropertyOptions.ARRAY_ORDERED,
• PropertyOptions.ARRAY_ALTERNATE or
• PropertyOptions.ARRAY_ALT_TEXT.

Note: the array options only need to be provided if the array is not already existing, otherwise you can set them to null or use XMPMeta.appendArrayItem(String, String, String).

itemValue - the value of the array item. Has the same usage as propValue in getProperty.

itemOptions - Option flags describing the item to append (PropertyOptions)

                             throws XMPException

Description copied from interface: XMPMeta

These functions provide convenient support for localized text properties, including a number of special and obscure aspects. Localized text properties are stored in alt-text arrays. They allow multiple concurrent localizations of a property value, for example a document title or copyright in several languages. The most important aspect of these functions is that they select an appropriate array item based on one or two RFC 3066 language tags. One of these languages, the "specific" language, is preferred and selected if there is an exact match. For many languages it is also possible to define a "generic" language that may be used if there is no specific language match. The generic language must be a valid RFC 3066 primary subtag, or the empty string. For example, a specific language of "en-US" should be used in the US, and a specific language of "en-UK" should be used in England. It is also appropriate to use "en" as the generic language in each case. If a US document goes to England, the "en-US" title is selected by using the "en" generic language and the "en-UK" specific language. It is considered poor practice, but allowed, to pass a specific language that is just an RFC 3066 primary tag. For example "en" is not a good specific language, it should only be used as a generic language. Passing "i" or "x" as the generic language is also considered poor practice but allowed. Advice from the W3C about the use of RFC 3066 language tags can be found at: http://www.w3.org/International/articles/language-tags/

Note: RFC 3066 language tags must be treated in a case insensitive manner. The XMP Toolkit does this by normalizing their capitalization:

• The primary subtag is lower case, the suggested practice of ISO 639.
• All 2 letter secondary subtags are upper case, the suggested practice of ISO 3166.
• All other subtags are lower case. The XMP specification defines an artificial language,
• "x-default", that is used to explicitly denote a default item in an alt-text array.

The XMP toolkit normalizes alt-text arrays such that the x-default item is the first item. The SetLocalizedText function has several special features related to the x-default item, see its description for details. The selection of the array item is the same for GetLocalizedText and SetLocalizedText:

• Look for an exact match with the specific language.
• If a generic language is given, look for a partial match.
• Look for an x-default item.
• Choose the first item.

A partial match with the generic language is where the start of the item's language matches the generic string and the next character is '-'. An exact match is also recognized as a degenerate case. It is fine to pass x-default as the specific language. In this case, selection of an x-default item is an exact match by the first rule, not a selection by the 3rd rule. The last 2 rules are fallbacks used when the specific and generic languages fail to produce a match. getLocalizedText returns information about a selected item in an alt-text array. The array item is selected according to the rules given above. Note: In a future version of this API a method using Java java.lang.Locale will be added.

Specified by:

getLocalizedText in interface XMPMeta

Parameters:

schemaNS - The namespace URI for the alt-text array. Has the same usage as in getProperty().

altTextName - The name of the alt-text array. May be a general path expression, must not be null or the empty string. Has the same namespace prefix usage as propName in getProperty().

genericLang - The name of the generic language as an RFC 3066 primary subtag. May be null or the empty string if no generic language is wanted.

specificLang - The name of the specific language as an RFC 3066 tag. Must not be null or the empty string.

Returns:

Returns an XMPProperty containing the value, the actual language and the options if an appropriate alternate collection item exists, null if the property. does not exist.

Throws:

XMPException

                      throws XMPException

Description copied from interface: XMPMeta

Modifies the value of a selected item in an alt-text array. Creates an appropriate array item if necessary, and handles special cases for the x-default item. If the selected item is from a match with the specific language, the value of that item is modified. If the existing value of that item matches the existing value of the x-default item, the x-default item is also modified. If the array only has 1 existing item (which is not x-default), an x-default item is added with the given value. If the selected item is from a match with the generic language and there are no other generic matches, the value of that item is modified. If the existing value of that item matches the existing value of the x-default item, the x-default item is also modified. If the array only has 1 existing item (which is not x-default), an x-default item is added with the given value. If the selected item is from a partial match with the generic language and there are other partial matches, a new item is created for the specific language. The x-default item is not modified. If the selected item is from the last 2 rules then a new item is created for the specific language. If the array only had an x-default item, the x-default item is also modified. If the array was empty, items are created for the specific language and x-default. Note: In a future version of this API a method using Java java.lang.Locale will be added.

Specified by:

Parameters:

schemaNS - The namespace URI for the alt-text array. Has the same usage as in getProperty().

altTextName - The name of the alt-text array. May be a general path expression, must not be null or the empty string. Has the same namespace prefix usage as propName in getProperty().

genericLang - The name of the generic language as an RFC 3066 primary subtag. May be null or the empty string if no generic language is wanted.

getProperty

public XMPProperty getProperty(java.lang.String schemaNS,
                      java.lang.String propName)
                        throws XMPException

Description copied from interface: XMPMeta

The property value getter-methods all take a property specification: the first two parameters are always the top level namespace URI (the "schema" namespace) and the basic name of the property being referenced. See the introductory discussion of path expression usage for more information.

All of the functions return an object inherited from PropertyBase or null if the property does not exists. The result object contains the value of the property and option flags describing the property. Arrays and the non-leaf levels of nodes do not have values.

See PropertyOptions for detailed information about the options.

This is the simplest property getter, mainly for top level simple properties or after using the path composition functions in XMPPathFactory.

Specified by:

getProperty in interface XMPMeta

Parameters:

schemaNS - The namespace URI for the property. May be null or the empty string if the first component of the propName path contains a namespace prefix. The URI must be for a registered namespace.

propName - The name of the property. May be a general path expression, must not be null or the empty string. Using a namespace prefix on the first component is optional. If present without a schemaNS value then the prefix specifies the namespace. The prefix must be for a registered namespace. If both a schemaNS URI and propName prefix are present, they must be corresponding parts of a registered namespace.

Returns:

Returns a XMPProperty containing the value and the options or null if the property does not exist.

Throws:

XMPException

                       java.lang.String qualName)
                         throws XMPException

Description copied from interface: XMPMeta

Provides access to a qualifier attached to a property. The namespace for the qualifier is passed as a URI, you need not worry about the path string syntax. In many regards qualifiers are like struct fields. See the introductory discussion of qualified properties for more information.

The names of qualifiers should be XML qualified names, that is within an XML namespace. The path syntax for a qualified name uses the namespace prefix. This is unreliable since the prefix is never guaranteed. The URI is the formal name, the prefix is just a local shorthand in a given sequence of XML text.

Note: Qualifiers are only supported for simple leaf properties at this time.

Specified by:

getQualifier in interface XMPMeta

Parameters:

schemaNS - The namespace URI for the struct. Has the same usage as in getProperty.

propName - The name of the property to which the qualifier is attached. May be a general path expression, must not be null or the empty string. Has the same namespace prefix usage as in getProperty().

qualNS - The namespace URI for the qualifier. Has the same URI and prefix usage as the schemaNS parameter.

qualName - The name of the qualifier. Must be a single XML name, must not be null or the empty string. Has the same namespace prefix usage as the propName parameter.

Returns:

Returns a XMPProperty containing the value and the options of the qualifier or null if the property does not exist. The name of the qualifier must be a single XML name, must not be null or the empty string. Has the same namespace prefix usage as the propName parameter.

The value of the qualifier is only set if it has one (Arrays and non-leaf levels of structs do not have values).

                           throws XMPException

Description copied from interface: XMPMeta

Provides access to fields within a nested structure. The namespace for the field is passed as a URI, you need not worry about the path string syntax.

The names of fields should be XML qualified names, that is within an XML namespace. The path syntax for a qualified name uses the namespace prefix.

Specified by:

getStructField in interface XMPMeta

Parameters:

schemaNS - The namespace URI for the struct. Has the same usage as in getProperty.

structName - The name of the struct. May be a general path expression, must not be null or the empty string. Has the same namespace prefix usage as propName in getProperty().

fieldNS - The namespace URI for the field. Has the same URI and prefix usage as the schemaNS parameter.

fieldName - The name of the field. Must be a single XML name, must not be null or the empty string. Has the same namespace prefix usage as the structName parameter.

Returns:

Returns a XMPProperty containing the value and the options or null if the property does not exist. Arrays and non-leaf levels of structs do not have values.

Parameters:

schemaNS - Optional schema namespace URI to restrict the iteration. Omitted (visit all schema) by passing null or empty String.

propName - Optional property name to restrict the iteration. May be an arbitrary path expression. Omitted (visit all properties) by passing null or empty String. If no schema URI is given, it is ignored.

options - Option flags to control the iteration. See IteratorOptions for details.

Returns:

Returns an XMPIterator for this XMPMeta-object considering the given options.

Throws:

XMPException - Wraps all errors and exceptions that may occur.

               PropertyOptions options)
                 throws XMPException

Description copied from interface: XMPMeta

The property value setters all take a property specification, their differences are in the form of this. The first two parameters are always the top level namespace URI (the schema namespace) and the basic name of the property being referenced. See the introductory discussion of path expression usage for more information.

All of the functions take a string value for the property and option flags describing the property. The value must be Unicode in UTF-8 encoding. Arrays and non-leaf levels of structs do not have values. Empty arrays and structs may be created using appropriate option flags. All levels of structs that is assigned implicitly are created if necessary. appendArayItem implicitly creates the named array if necessary.

See PropertyOptions for detailed information about the options.

This is the simplest property setter, mainly for top level simple properties or after using the path composition functions in XMPPathFactory.

Specified by:

setProperty in interface XMPMeta

Parameters:

schemaNS - The namespace URI for the property. Has the same usage as in getProperty.

propName - The name of the property. Has the same usage as in getProperty().

propValue - the value for the property (only leaf properties have a value). Arrays and non-leaf levels of structs do not have values. Must be null if the value is not relevant.
The value is automatically detected: Boolean, Integer, Long, Double, XMPDateTime and byte[] are handled, on all other toString() is called.

options - Option flags describing the property. See the earlier description.

Throws:

XMPException

setProperty

public void setProperty(java.lang.String schemaNS,
               java.lang.String propName,

                 throws XMPException

Specified by:

Parameters:

schemaNS - The namespace URI

                java.lang.String qualName,
                java.lang.String qualValue,
                PropertyOptions options)
                  throws XMPException

Description copied from interface: XMPMeta

Provides access to a qualifier attached to a property. The namespace for the qualifier is passed as a URI, you need not worry about the path string syntax. In many regards qualifiers are like struct fields. See the introductory discussion of qualified properties for more information. The names of qualifiers should be XML qualified names, that is within an XML namespace. The path syntax for a qualified name uses the namespace prefix, which is unreliable because the prefix is never guaranteed. The URI is the formal name, the prefix is just a local shorthand in a given sequence of XML text. The property the qualifier will be attached has to exist.

Specified by:

setQualifier in interface XMPMeta

Parameters:

schemaNS - The namespace URI for the struct. Has the same usage as in getProperty.

propName - The name of the property to which the qualifier is attached. Has the same usage as in getProperty.

qualNS - The namespace URI for the qualifier. Has the same URI and prefix usage as the schemaNS parameter.

qualName - The name of the qualifier. Must be a single XML name, must not be null or the empty string. Has the same namespace prefix usage as the propName parameter.

qualValue - A pointer to the null terminated UTF-8 string that is the value of the qualifier, if the qualifier has a value. Has the same usage as propValue in getProperty.

options - Option flags describing the qualifier. See the earlier description.

Throws:

XMPException

setStructField in interface XMPMeta

Parameters:

schemaNS - The namespace URI for the struct. Has the same usage as in getProperty.

structName - The name of the struct. May be a general path expression, must not be null or the empty string. Has the same namespace prefix usage as propName in getProperty.

fieldNS - The namespace URI for the field. Has the same URI and prefix usage as the schemaNS parameter.

fieldName - The name of the field. Must be a single XML name, must not be null or the empty string. Has the same namespace prefix usage as the structName parameter.

Parameters:

options - optional parsing options.

Throws:

XMPException - Wraps all errors and exceptions that may occur.
