Method Detail

compare

public static int compare(String document1,
                          String document2)
                   throws IOException

Compares two XML documents located at 2 given URLs, returning the number of differences or 0 if both documents are 'XML equivalent'.

Parameters:

document1 - the URL of the first XML document.

document2 - the URL of the second XML document.

Returns:

an int indicating the number of differences or 0 if both documents are 'XML equivalent'.

Throws:

IOException - if an error occurs reading either XML document

getClass

public static Class getClass(String name,
                             ClassLoader loader)
                      throws ClassNotFoundException

Returns the class associated with the given name.

Parameters:

name - the fully qualified name of the class to return. Primitives are handled through their name and not their class name. For instance 'boolean' should be used instead of 'java.lang.Boolean.TYPE'.

loader - the ClassLoader to use if the class needs to be loaded

Returns:

the class associated with given name.

Throws:

ClassNotFoundException - if the given class cannot be loaded using the provided class loader.

instantiateObject

public static Object instantiateObject(String type,
                                       String value,
                                       ClassLoader loader)
                                throws ClassNotFoundException,
                                       MarshalException

Converts the given value to a Java representation that corresponds to the given type.

Parameters:

value - the value to be converted

type - a string representation of the java type.

loader - an optional ClassLoader used in case we need to use the Unmarshaller to retrieve a complex java object.

Returns:

an java object that corresponds to the given value converted to a java type according to the type passed as parameter.

Throws:

ClassNotFoundException - if the type is not a recognized primitive type and the class loader provided cannot load the type

MarshalException - if the type is not a recognized primitive type and no Marshaller can be found for that type
