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.

Constructor Detail

ProcessingInstructionImpl

public ProcessingInstructionImpl(CoreDocumentImpl ownerDoc,
                                 java.lang.String target,
                                 java.lang.String data)

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 target

Overrides:

getNodeName in class NodeImpl

getTarget

public java.lang.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

getData

public java.lang.String getData()

A PI's data content tells the processor what we actually want it to do. It is defined slightly differently in HTML and XML.

In XML, the data begins with the non-whitespace character immediately after the target -- @see getTarget().

In HTML, the data begins with the character immediately after the "<?" token that begins the PI.

Note that getNodeValue is aliased to getData

Specified by:

getData in interface ProcessingInstruction

Overrides:

getData in class CharacterDataImpl

Tags copied from interface: ProcessingInstruction

Throws:

DOMException - NO_MODIFICATION_ALLOWED_ERR: Raised when the node is readonly.

setData

public void setData(java.lang.String data)

Change the data content of this PI. Note that setData is aliased to setNodeValue.

Specified by:

setData in interface ProcessingInstruction

Overrides:

setData in class CharacterDataImpl

Throws:

DOMException(NO_MODIFICATION_ALLOWED_ERR) - if node is read-only.
