public class EntityImpl
extends ParentNode
implements org.w3c.dom.Entity

Entity nodes hold the reference data for an XML Entity -- either parsed or unparsed. The nodeName (inherited from Node) will contain the name (if any) of the Entity. Its data will be contained in the Entity's children, in exactly the structure which an EntityReference to this name will present within the document's body.

Note that this object models the actual entity, _not_ the entity declaration or the entity reference.

An XML processor may choose to completely expand entities before the structure model is passed to the DOM; in this case, there will be no EntityReferences in the DOM tree.

Quoting the 10/01 DOM Proposal,

"The DOM Level 1 does not support editing Entity nodes; if a user wants to make changes to the contents of an Entity, every related EntityReference node has to be replaced in the structure model by a clone of the Entity's contents, and then the desired changes must be made to each of those clones instead. All the descendants of an Entity node are readonly."

I'm interpreting this as: It is the parser's responsibilty to call the non-DOM operation setReadOnly(true,true) after it constructs the Entity. Since the DOM explicitly decided not to deal with this, _any_ answer will involve a non-DOM operation, and this is the simplest solution.

This class is based on an implementation from the Apache XML Project. In future releases the XML parser, XSLT processor, and associated classes will likely be updated to be based on a later version of the Apache implementations. Since Apache does not guarantee backwards compatibility between versions of their software, we cannot guarantee backwards compatibility of any of the classes contained in the weblogic.apache package or sub-packages.

Field Detail

name

protected java.lang.String name

Entity name.

publicId

protected java.lang.String publicId

Public identifier.

systemId

protected java.lang.String systemId

System identifier.

notationName

protected java.lang.String notationName

Notation name.

Constructor Detail

EntityImpl

public EntityImpl(DocumentImpl ownerDoc,
                  java.lang.String name)

Factory constructor.

Method Detail

getNodeType

public short getNodeType()

A short integer indicating what type of node this is. The named constants for this value are defined in the org.w3c.dom.Node interface.

Overrides:: getNodeType in class NodeImpl

getNodeName

public java.lang.String getNodeName()

Returns the entity name

Overrides:: getNodeName in class NodeImpl

cloneNode

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

Clone node.

Overrides:: cloneNode in class ParentNode

getPublicId

public java.lang.String getPublicId()

The public identifier associated with the entity. If not specified, this will be null.

Specified by:: getPublicId in interface org.w3c.dom.Entity

getSystemId

public java.lang.String getSystemId()

The system identifier associated with the entity. If not specified, this will be null.

Specified by:: getSystemId in interface org.w3c.dom.Entity

getNotationName

public java.lang.String getNotationName()

Unparsed entities -- which contain non-XML data -- have a "notation name" which tells applications how to deal with them. Parsed entities, which are in XML format, don't need this and set it to null.

Specified by:: getNotationName in interface org.w3c.dom.Entity

setPublicId

public void setPublicId(java.lang.String id)

NON-DOM The public identifier associated with the entity. If not specified, this will be null.

setSystemId

public void setSystemId(java.lang.String id)

NON-DOM The system identifier associated with the entity. If not specified, this will be null.

setNotationName

public void setNotationName(java.lang.String name)

NON-DOM Unparsed entities -- which contain non-XML data -- have a "notation name" which tells applications how to deal with them. Parsed entities, which are in XML format, don't need this and set it to null.
