getCopyHelper

public CopyHelper getCopyHelper()
Description copied from interface: HelperContext
Gets the CopyHelper to use in this context.

Specified by:
getCopyHelper in interface HelperContext
Returns:
a CopyHelper object

getDataFactory

public DataFactory getDataFactory()
Description copied from interface: HelperContext
Gets the DataFactory to use in this context.

Specified by:
getDataFactory in interface HelperContext
Returns:
a DataFactory object

getDataHelper

public DataHelper getDataHelper()
Description copied from interface: HelperContext
Gets the DataHelper to use in this context.

Specified by:
getDataHelper in interface HelperContext
Returns:
a DataHelper object

getEqualityHelper

public EqualityHelper getEqualityHelper()
Description copied from interface: HelperContext
Gets the EqualityHelper to use in this context.

Specified by:
getEqualityHelper in interface HelperContext
Returns:
an EqualityHelper object

getTypeHelper

public TypeHelper getTypeHelper()
Description copied from interface: HelperContext
Gets the TypeHelper to use in this context.

Specified by:
getTypeHelper in interface HelperContext
Returns:
a TypeHelper object

getXMLHelper

public XMLHelper getXMLHelper()
Description copied from interface: HelperContext
Gets the XMLHelper to use in this context.

Specified by:
getXMLHelper in interface HelperContext
Returns:
an XMLHelper object

getXSDHelper

public XSDHelper getXSDHelper()

createResolvable

public ExternalizableDelegator.Resolvable createResolvable()

createResolvable

public ExternalizableDelegator.Resolvable createResolvable(java.lang.Object target)

putHelperContext

public static void putHelperContext(java.lang.ClassLoader key,
                                    HelperContext value)
INTERNAL: Put a ClassLoader/HelperContext key/value pair in the Thread HelperContext map. If Thread.currentThread().getContextClassLoader() == key during getHelperContext() call then the HelperContext (value) will be returned. This method will overwrite an existing entry in the map with the same ClassLoader key.

Parameters:
key - class loader
value - helper context

removeHelperContext

public static void removeHelperContext(java.lang.ClassLoader key)
INTERNAL: Remove a ClassLoader/HelperContext key/value pair from the Thread HelperContext map.

Parameters:
key - class loader

getHelperContext

public static HelperContext getHelperContext()
INTERNAL: Return the helper context for a given key. The key will either be a ClassLoader or a String (representing an application name). A new context will be created and put in the map if none exists for the given key. The key is assumed to be non-null - getDelegateKey should always return either a string representing the application name (for WLS) or a class loader. This is relevant since 'putIfAbsent' will throw a null pointer exception if the key is null.


makeDefaultContext

public void makeDefaultContext()
ADVANCED Promote this helper context to be the default or global one. This will completely replace the existing default context including all types and properties defined.
