All Implemented Interfaces:: Callback, ContentHandler, javax.xml.rpc.encoding.Deserializer, Deserializer, DTDHandler, EntityResolver, ErrorHandler, Serializable

public class ArrayDeserializer
extends DeserializerImpl

An ArrayDeserializer handles deserializing SOAP arrays.

Nested Class Summary

class ArrayDeserializer.ArrayListExtension
          During processing, the Array Deserializer stores the array in an ArrayListExtension class.

Method Summary

void characters(char[] chars, int i, int i1)


SOAPHandler onStartChild(String namespace, String localName, String prefix, Attributes attributes, DeserializationContext context)
          onStartChild is called on each child element.

void onStartElement(String namespace, String localName, String prefix, Attributes attributes, DeserializationContext context)
          This method is invoked after startElement when the element requires deserialization (i.e.

void setChildValue(Object value, Object hint)
          set is called during deserialization to assign the Object value to the array position indicated by hint.

void valueComplete()
          When valueComplete() is invoked on the array, first convert the array value into the expected array.

Method Detail

onStartElement

public void onStartElement(String namespace,
                           String localName,
                           String prefix,
                           Attributes attributes,
                           DeserializationContext context)
                    throws SAXException

This method is invoked after startElement when the element requires deserialization (i.e. the element is not an href & the value is not nil) DeserializerImpl provides default behavior, which simply involves obtaining a correct Deserializer and plugging its handler.

Specified by:: onStartElement in interface Deserializer
Overrides:: onStartElement in class DeserializerImpl

Parameters:: namespace - is the namespace of the element; localName - is the name of the element; prefix - is the prefix of the element; attributes - are the attrs on the element...used to get the type; context - is the DeserializationContext
Throws:: SAXException

onStartChild

public SOAPHandler onStartChild(String namespace,
                                String localName,
                                String prefix,
                                Attributes attributes,
                                DeserializationContext context)
                         throws SAXException

onStartChild is called on each child element.

Specified by:: onStartChild in interface Deserializer
Overrides:: onStartChild in class DeserializerImpl

Parameters:: namespace - is the namespace of the child element; localName - is the local name of the child element; prefix - is the prefix used on the name of the child element; attributes - are the attributes of the child element; context - is the deserialization context.
Returns:: is a Deserializer to use to deserialize a child (must be a derived class of SOAPHandler) or null if no deserialization should be performed.
Throws:: SAXException

characters

public void characters(char[] chars,
                       int i,
                       int i1)
                throws SAXException

Throws:: SAXException

setChildValue

public void setChildValue(Object value,
                          Object hint)
                   throws SAXException

set is called during deserialization to assign the Object value to the array position indicated by hint. The hint is always a single Integer. If the array being deserialized is a multi-dimensional array, the hint is converted into a series of indices to set the correct nested position. The array deserializer always deserializes into an ArrayList, which is converted and copied into the actual array after completion (by valueComplete). It is important to wait until all indices have been processed before invoking valueComplete.

Specified by:: setChildValue in interface Deserializer
Overrides:: setChildValue in class DeserializerImpl

Parameters:: value - value of the array element; hint - index of the array element (Integer)
Throws:: SAXException

valueComplete

public void valueComplete()
                   throws SAXException

When valueComplete() is invoked on the array, first convert the array value into the expected array. Then call super.valueComplete() to inform referents that the array value is ready.

Specified by:: valueComplete in interface Deserializer
Overrides:: valueComplete in class DeserializerImpl

Throws:: SAXException
