Method Detail

setSource

public abstract void setSource(Object elem)

Description copied from interface: XMLElement

Accepts an Object representing an XML element. The implementation should check that it is of a type appropriate for the underlying XML parser or XML Object model being used. For example, a DOM implementation might expect an org.w3c.dom.Element while an AXIOM implementation might expect org.apache.axiom.om.OMElement.

Specified by:

setSource in interface XMLElement

Parameters:

elem - the Object representing the XML element

getSource

public final Object getSource()

Description copied from interface: XMLElement

Returns an Object representing an XML element, which the caller must cast to the expected type. For example, for DOM implementation we might cast it to an org.w3c.dom.Element whereas an AXIOM implementation might cast it to an org.apache.axiom.om.OMElement.

Specified by:

getSource in interface XMLElement

Returns:

an Object representing the XML element

getAttributeValue

public final String getAttributeValue(String attrName)

Description copied from interface: XMLElement

Returns the value of the specified attribute or null if it is not found.

Specified by:

getAttributeValue in interface XMLElement

attrName - name of attribute to look for

Returns:

the attribute value including prefix if present

doGetAttributeValue
