public interface XMLClassDescriptor
extends ClassDescriptor

A class descriptor for describing relationships between a Class and an XML element or complexType. This class implements org.exolab.castor.mapping.ClassDescriptor, yet adds extra methods for handling XML. All fields are of type XMLFieldDescriptor.

Method Detail

getAttributeDescriptors

XMLFieldDescriptor[] getAttributeDescriptors()

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

Returns:

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

getContentDescriptor

XMLFieldDescriptor getContentDescriptor()

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

Returns:

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

getElementDescriptors

XMLFieldDescriptor[] getElementDescriptors()

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

Returns:

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

getFieldDescriptor

XMLFieldDescriptor getFieldDescriptor(String name,
                                    String namespace,
                                    NodeType nodeType)

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

Parameters:

name - The xml name to match against.

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

String getNameSpacePrefix()

Returns the namespace prefix to use when marshalling as XML.

Returns:

the namespace prefix to use when marshalling as XML.

getNameSpaceURI

String getNameSpaceURI()

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

Returns:

the namespace URI used when marshalling and unmarshalling as XML.

getValidator

TypeValidator getValidator()

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

Returns:

the type validator for the class described by this ClassDescriptor.

getXMLName

String getXMLName()

Returns the XML Name for the Class being described.

Returns:

the XML name.

canAccept

boolean canAccept(String name,
                String namespace,
                Object object)

Returns true if the given object, represented by this XMLClassDescriptor, can accept a value for the member associated with the given xml name and namespace.

An XMLClassDescriptor can accept a value for a field if it contains a descriptor that matches the given xml name and namespace and if the given object can hold this field (i.e a value is not already set for this field).

Parameters:

name - the xml name of the field to check

namespace - the namespace uri

object - the object instance represented by this XMLCLassDescriptor

Returns:

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

checkDescriptorForCorrectOrderWithinSequence

void checkDescriptorForCorrectOrderWithinSequence(XMLFieldDescriptor elementDescriptor,
                                                UnmarshalState parentState,
                                                String xmlName)
                                                  throws ValidationException

Checks whether the given XMLFieldDescriptor is the one actually expected, given the natural order as defined by a sequence definition

Parameters:

elementDescriptor - The XML field descriptor to be checked

xmlName - TODO

Throws:

ValidationException - If the descriptor is not the one expected

isChoice

boolean isChoice()

Indicates whether the XML artifact described by this descriptor is a .

Returns:

True if the artifact described is a choice.
