Method Detail

getAttributeDescriptors

public XMLFieldDescriptor[] getAttributeDescriptors()

Returns the set of XMLFieldDescriptors for all members that should be marshalled as XML attributes.

Specified by:

getAttributeDescriptors in interface XMLClassDescriptor

Returns:

an array of XMLFieldDescriptors for all members that should be marshalled as XML attributes.

getContentDescriptor

public XMLFieldDescriptor getContentDescriptor()

Returns the XMLFieldDescriptor for the member that should be marshalled as text content.

Specified by:

getContentDescriptor in interface XMLClassDescriptor

Returns:

the XMLFieldDescriptor for the member that should be marshalled as text content.

getElementDescriptors

public XMLFieldDescriptor[] getElementDescriptors()

Returns the set of XMLFieldDescriptors for all members that should be marshalled as XML elements.

Specified by:

getElementDescriptors in interface XMLClassDescriptor

Returns:

an array of XMLFieldDescriptors for all members that should be marshalled as XML elements.

getFieldDescriptor

public XMLFieldDescriptor getFieldDescriptor(java.lang.String name,
                                             java.lang.String namespace,
                                             NodeType nodeType)

Returns the XML field descriptor matching the given xml name and nodeType. If NodeType is null, then either an AttributeDescriptor, or ElementDescriptor may be returned. Null is returned if no matching descriptor is available.

Specified by:

getFieldDescriptor in interface XMLClassDescriptor

Parameters:

name - the xml name to match against

namespace - the namespace uri

nodeType, - the NodeType to match against, or null if the node type is not known.

Returns:

the matching descriptor, or null if no matching descriptor is available.

getNameSpacePrefix

public java.lang.String getNameSpacePrefix()

Description copied from interface: XMLClassDescriptor

Returns the namespace prefix to use when marshalling as XML.

Specified by:

getNameSpacePrefix in interface XMLClassDescriptor

Returns:

the namespace prefix to use when marshalling as XML.

getNameSpaceURI

public java.lang.String getNameSpaceURI()

Description copied from interface: XMLClassDescriptor

Returns the namespace URI used when marshalling and unmarshalling as XML.

Specified by:

getNameSpaceURI in interface XMLClassDescriptor

Returns:

the namespace URI used when marshalling and unmarshalling as XML.

getValidator

public TypeValidator getValidator()

Returns a specific validator for the class described by this ClassDescriptor. A null value may be returned if no specific validator exists.

Specified by:

getValidator in interface XMLClassDescriptor

Returns:

the type validator for the class described by this ClassDescriptor.

getXMLName

public java.lang.String getXMLName()

Returns the XML Name for the Class being described.

Specified by:

getXMLName in interface XMLClassDescriptor

Returns:

the XML name.

toString

public java.lang.String toString()

getJavaClass in interface ClassDescriptor

Returns:

The Java class

getFields

public FieldDescriptor[] getFields()

Returns a list of fields represented by this descriptor.

Specified by:

getFields in interface ClassDescriptor

Returns:

A list of fields

getExtends

public ClassDescriptor getExtends()

Returns the class descriptor of the class extended by this class.

Specified by:

getExtends in interface ClassDescriptor

Returns:

The extended class descriptor

getIdentity

public FieldDescriptor getIdentity()

Returns the identity field, null if this class has no identity.

The identity field

getAccessMode

public AccessMode getAccessMode()

Returns the access mode specified for this class.

Specified by:

getAccessMode in interface ClassDescriptor

Returns:

The access mode

canAccept

public boolean canAccept(java.lang.String name,
                         java.lang.String namespace,
                         java.lang.Object object)

Returns true if the given object represented by this XMLClassDescriptor can accept a member whose name is given. An XMLClassDescriptor can accept a field if it contains a descriptor that matches the given name and if the given object can hold this field (i.e a value is not already set for this field).

This is mainly used for container object (that can contains other object), in this particular case the implementation will return null.

Specified by:

canAccept in interface XMLClassDescriptor

Parameters:

name - the xml name of the field to check

namespace - the namespace uri

object - the object represented by this XMLCLassDescriptor

Returns:

true if the given object represented by this XMLClassDescriptor can accept a member whose name is given.
