Class MessageElement

java.lang.Object

org.apache.axis.message.NodeImpl

org.apache.axis.message.MessageElement

All Implemented Interfaces:

java.io.Serializable, java.lang.Cloneable, SOAPElement, org.w3c.dom.Element, org.w3c.dom.Node, org.w3c.dom.NodeList

Direct Known Subclasses:

DetailEntry, RPCParam, SOAPBody, SOAPBodyElement, SOAPEnvelope, SOAPFaultElement, SOAPHeader, SOAPHeaderElement

public class MessageElement
extends NodeImpl
implements SOAPElement, java.io.Serializable, org.w3c.dom.NodeList, java.lang.Cloneable

MessageElement is the base type of nodes of the SOAP message parse tree. Note: it was made Serializable to help users of Apache SOAP who had exploited the serializability of the DOM tree to migrate to Axis.

              DeserializationContext context)
               throws AxisFault

Advanced constructor used for deserialization.

1. The context provides the mappings and Sax event recorder
2. The soap messaging style is determined from the current message context, defaulting to SOAP1.1 if there is no current context.
3. if there is an id attribute (any namespace), then the ID is registered with DeserializationContext.registerElementByID(String, MessageElement) ;a new recorder is created if needed.
4. If there is an attribute "root" in the default SOAP namespace, then it is examined to see if it marks the element as root (value=="1" or not)
5. If there is an arrayType attribute then we assume we are an array and set our typeQName field appropriately.
6. The href field is set if there is a relevant href value

Parameters:

namespace - namespace namespace of element

localPart - local name local name of element

prefix - prefix prefix of element

attributes - attributes to save as our attributes

context - deserialization context for this message element

Method Detail

getDeserializationContext

public DeserializationContext getDeserializationContext()

Retrieve the DeserializationContext associated with this MessageElement

Returns:

The DeserializationContext associated with this MessageElement

setFixupDeserializer

public void setFixupDeserializer(Deserializer dser)

getFixupDeserializer

public Deserializer getFixupDeserializer()

ID or null for no ID

getHref

public java.lang.String getHref()

getAttributesEx

public org.xml.sax.Attributes getAttributesEx()

Returns:

attributes. If this equals NullAttributes.singleton it is null

cloneNode

public org.w3c.dom.Node cloneNode(boolean deep)

Returns a duplicate of this node, i.e., serves as a generic copy constructor for nodes. The duplicate node has no parent; ( parentNode is null.).
Cloning an Element copies all attributes and their values, including those generated by the XML processor to represent defaulted attributes, but this method does not copy any text it contains unless it is a deep clone, since the text is contained in a child Text node. Cloning an Attribute directly, as opposed to be cloned as part of an Element cloning operation, returns a specified attribute ( specified is true). Cloning any other type of node simply returns a copy of this node.
Note that cloning an immutable subtree results in a mutable copy, but the children of an EntityReference clone are readonly . In addition, clones of unspecified Attr nodes are specified. And, cloning Document, DocumentType, Entity, and Notation nodes is implementation dependent.

Specified by:

cloneNode in interface org.w3c.dom.Node

Overrides:

cloneNode in class NodeImpl

Parameters:

deep - If true, recursively clone the subtree under the specified node; if false, clone only the node itself (and its attributes, if it is an Element).

Returns:

The duplicate node.

childDeepCloned

protected void childDeepCloned(NodeImpl oldNode,
                   NodeImpl newNode)
