Method Detail

• getMechanismType

  public java.lang.String getMechanismType()

  JAX-RPC compliant method which returns mechanism type.

  Specified by:

  getMechanismType in interface Deserializer

  Returns:

  XML processing mechanism type

• getValue

  public java.lang.Object getValue()

  Get the deserialized value.

  Specified by:

  getValue in interface Deserializer

  Returns:

  Object representing deserialized value or null

• setValue

  public void setValue​(java.lang.Object value)

  Set the deserialized value.

  Specified by:

  setValue in interface Deserializer

  Parameters:

  value - Object representing deserialized value

• getValue

  public java.lang.Object getValue​(java.lang.Object hint)

  If the deserializer has component values (like ArrayDeserializer) this method gets the specific component via the hint. The default implementation returns null.

  Specified by:

  getValue in interface Deserializer

  Returns:

  Object representing deserialized value or null

• setChildValue

  public void setChildValue​(java.lang.Object value,
                            java.lang.Object hint)
                     throws org.xml.sax.SAXException

  If the deserializer has component values (like ArrayDeserializer) this method sets the specific component via the hint. The default implementation does nothing.

  Specified by:

  setChildValue in interface Deserializer

  Parameters:

  hint - Object representing deserialized value or null

  value - Object representing deserialized value or null

  Throws:

  org.xml.sax.SAXException

• setValue

  public void setValue​(java.lang.Object value,
                       java.lang.Object hint)
                throws org.xml.sax.SAXException

  Specified by:

  setValue in interface Callback

  Throws:

  org.xml.sax.SAXException

• setDefaultType

  public void setDefaultType​(QName qName)

  In some circumstances an element may not have a type attribute, but a default type qname is known from information in the container. For example, an element of an array may not have a type= attribute, so the default qname is the component type of the array. This method is used to communicate the default type information to the deserializer.

  Specified by:

  setDefaultType in interface Deserializer

• getDefaultType

  public QName getDefaultType()

  Specified by:

  getDefaultType in interface Deserializer

• registerValueTarget

  public void registerValueTarget​(Target target)

  For deserializers of non-primitives, the value may not be known until later (due to multi-referencing). In such cases the deserializer registers Target object(s). When the value is known, the set(value) will be invoked for each Target registered with the Deserializer. The Target object abstracts the function of setting a target with a value. See the Target interface for more info.

  Specified by:

  registerValueTarget in interface Deserializer

  Parameters:

  target -

• getValueTargets

  public java.util.Vector getValueTargets()

  Get the Value Targets of the Deserializer.

  Specified by:

  getValueTargets in interface Deserializer

  Returns:

  Vector of Target objects or null

• removeValueTargets

  public void removeValueTargets()

  Remove the Value Targets of the Deserializer.

  Specified by:

  removeValueTargets in interface Deserializer

• moveValueTargets

  public void moveValueTargets​(Deserializer other)

  Move someone else's targets to our own (see DeserializationContext) The DeserializationContext only allows one Deserializer to wait for a unknown multi-ref'ed value. So to ensure that all of the targets are updated, this method is invoked to copy the Target objects to the waiting Deserializer.

  Specified by:

  moveValueTargets in interface Deserializer

  Parameters:

  other - is the Deserializer to copy targets from.

• componentsReady

  public boolean componentsReady()

  Some deserializers (ArrayDeserializer) require all of the component values to be known before the value is complete. (For the ArrayDeserializer this is important because the elements are stored in an ArrayList, and all values must be known before the ArrayList is converted into the expected array. This routine is used to indicate when the components are ready. The default (true) is useful for most Deserializers.

  Specified by:

  componentsReady in interface Deserializer

• valueComplete

  public void valueComplete()
                     throws org.xml.sax.SAXException

  The valueComplete() method is invoked when the end tag of the element is read. This results in the setting of all registered Targets (see registerValueTarget). Note that the valueComplete() only processes the Targets if componentReady() returns true. So if you override componentReady(), then your specific Deserializer will need to call valueComplete() when your components are ready (See ArrayDeserializer)

  Specified by:

  valueComplete in interface Deserializer

  Throws:

  org.xml.sax.SAXException

• addChildDeserializer

  public void addChildDeserializer​(Deserializer dSer)

• startElement

  public void startElement​(java.lang.String namespace,
                           java.lang.String localName,
                           java.lang.String prefix,
                           org.xml.sax.Attributes attributes,
                           DeserializationContext context)
                    throws org.xml.sax.SAXException

  This method is invoked when an element start tag is encountered. DeserializerImpl provides default behavior, which involves the following: - directly handling the deserialization of a nill value - handling the registration of the id value. - handling the registration of a fixup if this element is an href. - calling onStartElement to do the actual deserialization if not nill or href cases.

  Specified by:

  startElement in interface Deserializer

  Overrides:

  startElement in class SOAPHandler

  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 attributes on the element...used to get the type

  context - is the DeserializationContext Normally a specific Deserializer (FooDeserializer) should extend DeserializerImpl. Here is the flow that will occur in such cases: 1) DeserializerImpl.startElement(...) will be called and do the id/href/nill stuff. 2) If real deserialization needs to take place DeserializerImpl.onStartElement will be invoked, which will attempt to install the specific Deserializer (FooDeserializer) 3) The FooDeserializer.startElement(...) will be called to do the Foo specific stuff. This results in a call to FooDeserializer.onStartElement(...) if startElement was not overridden. 4) The onChildElement(...) method is called for each child element. Nothing occurs if not overridden. The FooDeserializer.onStartChild(...) method should return the deserializer for the child element. 5) When the end tag is reached, the endElement(..) method is invoked. The default behavior is to handle hrefs/ids, call onEndElement and then call the Deserializer valueComplete method. So the methods that you potentially want to override are: onStartElement, onStartChild, componentsReady, setValue(object, hint) You probably should not override startElement or endElement. If you need specific behaviour at the end of the element consider overriding onEndElement. See the pre-existing Deserializers for more information.

  Throws:

  org.xml.sax.SAXException

• onStartElement

  public void onStartElement​(java.lang.String namespace,
                             java.lang.String localName,
                             java.lang.String prefix,
                             org.xml.sax.Attributes attributes,
                             DeserializationContext context)
                      throws org.xml.sax.SAXException

  This method is invoked after startElement when the element requires deserialization (i.e. the element is not an href and 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

  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 attributes on the element...used to get the type

  context - is the DeserializationContext

  Throws:

  org.xml.sax.SAXException

• onStartChild

  public SOAPHandler onStartChild​(java.lang.String namespace,
                                  java.lang.String localName,
                                  java.lang.String prefix,
                                  org.xml.sax.Attributes attributes,
                                  DeserializationContext context)
                           throws org.xml.sax.SAXException

  onStartChild is called on each child element. The default behavior supplied by DeserializationImpl is to do nothing. A specific deserializer may perform other tasks. For example a BeanDeserializer will construct a deserializer for the indicated property and return it.

  Specified by:

  onStartChild in interface Deserializer

  Overrides:

  onStartChild in class SOAPHandler

  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:

  org.xml.sax.SAXException

• endElement

  public final void endElement​(java.lang.String namespace,
                               java.lang.String localName,
                               DeserializationContext context)
                        throws org.xml.sax.SAXException

  endElement is called when the end element tag is reached. It handles href/id information for multi-ref processing and invokes the valueComplete() method of the deserializer which sets the targets with the deserialized value.

  Specified by:

  endElement in interface Deserializer

  Overrides:

  endElement in class SOAPHandler

  Parameters:

  namespace - is the namespace of the child element

  localName - is the local name of the child element

  context - is the deserialization context

  Throws:

  org.xml.sax.SAXException

• onEndElement

  public void onEndElement​(java.lang.String namespace,
                           java.lang.String localName,
                           DeserializationContext context)
                    throws org.xml.sax.SAXException

  onEndElement is called by endElement. It is not called if the element has an href.

  Specified by:

  onEndElement in interface Deserializer

  Parameters:

  namespace - is the namespace of the child element

  localName - is the local name of the child element

  context - is the deserialization context

  Throws:

  org.xml.sax.SAXException
