public ExtensionRegistry()
Creates the extension registry, and sets the defaultSerializer and defaultDeserializer properties to instances of an UnknownExtensionSerializer, and an UnknownExtensionDeserializer, respectively.

Method Detail

createExtension

public ExtensibilityElement createExtension(Class parentType, QName elementType)
Create an instance of the type which was declared to be used to represent extensibility elements with qnames matching elementType, when intended to exist as children of the specified parentType. This method allows a user to instantiate an extensibility element without having to know the implementing type.

Parameters: parentType a class object indicating where in the WSDL definition this extension will exist. For example, javax.wsdl.Binding.class would be used to indicate this extensibility element is going to be added to the list of extensibility elements belonging to a javax.wsdl.Binding, after being instantiated. elementType the qname of the extensibility element

Returns: a new instance of the type used to represent the specified extension

See Also: ExtensionRegistry

getAllowableExtensions

public Set getAllowableExtensions(Class parentType)
Returns a set of QNames representing the extensibility elements that are allowed as children of the specified parent type. Basically, this method returns the keys associated with the set of extension deserializers registered for this parent type. Returns null if no extension deserializers are registered for this parent type.

getDefaultDeserializer

public ExtensionDeserializer getDefaultDeserializer()
Get the deserializer to be used when none is found for an encountered element. Default value is an instance of UnknownExtensionDeserializer.

See Also: UnknownExtensionDeserializer

getDefaultSerializer

public ExtensionSerializer getDefaultSerializer()
Get the serializer to be used when none is found for an extensibility element. Default value is an instance of UnknownExtensionSerializer.

See Also: UnknownExtensionSerializer

mapExtensionTypes

public void mapExtensionTypes(Class parentType, QName elementType, Class extensionType)
Declare that the specified extensionType is the concrete class which should be used to represent extensibility elements with qnames matching elementType, that are intended to exist as children of the specified parentType.

Parameters: parentType a class object indicating where in the WSDL definition this extension would exist. For example, javax.wsdl.Binding.class would be used to indicate this extensibility element would be added to the list of extensibility elements belonging to a javax.wsdl.Binding, after being instantiated. elementType the qname of the extensibility element extensionType the concrete class which should be instantiated

See Also: ExtensionRegistry

queryDeserializer

public ExtensionDeserializer queryDeserializer(Class parentType, QName elementType)
Look up the deserializer for the extensibility element with the qname elementType, which was encountered as an immediate child of the element represented by the specified parentType.

Parameters: parentType a class object indicating where in the WSDL document this extensibility element was encountered. For example, javax.wsdl.Binding.class would be used to indicate this element was encountered as an immediate child of a <wsdl:binding> element. elementType the qname of the extensibility element

Returns: the extension deserializer, if one was found. If none was found, the behavior depends on the value of the defaultDeserializer property. If the defaultDeserializer property is set to a non-null value, that value is returned; otherwise, a WSDLException is thrown.

See Also: ExtensionRegistry setDefaultDeserializer

queryExtensionAttributeType

public int queryExtensionAttributeType(Class parentType, QName attrName)
Look up the type of the extensibility attribute with the qname attrName, which was defined on an element represented by the specified parentType.

Parameters: parentType a class object indicating where in the WSDL document this extensibility attribute was encountered. For example, javax.wsdl.Binding.class would be used to indicate this attribute was defined on a <wsdl:binding> element. attrName the qname of the extensibility attribute

Returns: one of the constants defined on the AttributeExtensible class

See Also: ExtensionRegistry AttributeExtensible

querySerializer

public ExtensionSerializer querySerializer(Class parentType, QName elementType)
Look up the serializer to use for the extensibility element with the qname elementType, which was encountered as a child of the specified parentType.

Parameters: parentType a class object indicating where in the WSDL definition this extension was encountered. For example, javax.wsdl.Binding.class would be used to indicate this extensibility element was found in the list of extensibility elements belonging to a javax.wsdl.Binding. elementType the qname of the extensibility element

Returns: the extension serializer, if one was found. If none was found, the behavior depends on the value of the defaultSerializer property. If the defaultSerializer property is set to a non-null value, that value is returned; otherwise, a WSDLException is thrown.

See Also: ExtensionRegistry setDefaultSerializer

registerDeserializer

public void registerDeserializer(Class parentType, QName elementType, ExtensionDeserializer ed)
Declare that the specified deserializer should be used to deserialize all extensibility elements with a qname matching elementType, when encountered as immediate children of the element represented by the specified parentType.

Parameters: parentType a class object indicating where in the WSDL document this extensibility element was encountered. For example, javax.wsdl.Binding.class would be used to indicate this element was encountered as an immediate child of a <wsdl:binding> element. elementType the qname of the extensibility element ed the extension deserializer to use

See Also: ExtensionRegistry

registerExtensionAttributeType

public void registerExtensionAttributeType(Class parentType, QName attrName, int attrType)
Declare that the type of the specified extension attribute, when it occurs as an attribute of the specified parent type, should be assumed to be attrType.

Parameters: parentType a class object indicating where in the WSDL document this extensibility attribute was encountered. For example, javax.wsdl.Binding.class would be used to indicate this attribute was defined on a <wsdl:binding> element. attrName the qname of the extensibility attribute attrType one of the constants defined on the AttributeExtensible class

See Also: ExtensionRegistry AttributeExtensible

registerSerializer

public void registerSerializer(Class parentType, QName elementType, ExtensionSerializer es)
Declare that the specified serializer should be used to serialize all extensibility elements with a qname matching elementType, when encountered as children of the specified parentType.

Parameters: parentType a class object indicating where in the WSDL definition this extension was encountered. For example, javax.wsdl.Binding.class would be used to indicate this extensibility element was found in the list of extensibility elements belonging to a javax.wsdl.Binding. elementType the qname of the extensibility element es the extension serializer to use

See Also: ExtensionRegistry

setDefaultDeserializer

public void setDefaultDeserializer(ExtensionDeserializer defaultDeser)
Set the deserializer to be used when none is found for an encountered element. Set this to null to have an exception thrown when unexpected extensibility elements are encountered. Default value is an instance of UnknownExtensionDeserializer.

See Also: UnknownExtensionDeserializer

setDefaultSerializer

public void setDefaultSerializer(ExtensionSerializer defaultSer)
Set the serializer to be used when none is found for an extensibility element. Set this to null to have an exception thrown when unexpected extensibility elements are encountered. Default value is an instance of UnknownExtensionSerializer.
