org.apache.xerces.dom.NodeImpl

org.apache.xerces.dom.ChildNode

org.apache.xerces.dom.CharacterDataImpl

org.apache.xerces.dom.ProcessingInstructionImpl

All Implemented Interfaces:

Serializable, Cloneable, EventTarget, Node, NodeList, ProcessingInstruction

Direct Known Subclasses:

DeferredProcessingInstructionImpl

public class ProcessingInstructionImpl
extends CharacterDataImpl
implements ProcessingInstruction

Processing Instructions (PIs) permit documents to carry processor-specific information alongside their actual content. PIs are most common in XML, but they are supported in HTML as well. This class inherits from CharacterDataImpl to reuse its setNodeValue method.

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.

Specified by:

getNodeType in interface Node

Specified by:

getNodeType in class NodeImpl

getNodeName

public String getNodeName()

Returns the target

Specified by:

getNodeName in interface Node

Specified by:

getNodeName in class NodeImpl

getTarget

public String getTarget()

A PI's "target" states what processor channel the PI's data should be directed to. It is defined differently in HTML and XML.

In XML, a PI's "target" is the first (whitespace-delimited) token following the " In HTML, target is always null.

Note that getNodeName is aliased to getTarget.

Specified by:

getTarget in interface ProcessingInstruction

getBaseURI

public String getBaseURI()

Returns the absolute base URI of this node or null if the implementation wasn't able to obtain an absolute URI. Note: If the URI is malformed, a null is returned.

Specified by:

getBaseURI in interface Node

Overrides:

getBaseURI in class NodeImpl

Returns:

The absolute base URI of this node or null.
