All Implemented Interfaces:
  java.lang.Cloneable, org.w3c.dom.events.EventTarget, org.w3c.dom.Node, org.w3c.dom.NodeList, org.w3c.dom.ProcessingInstruction, java.io.Serializable

Direct Known Subclasses:
  DeferredProcessingInstructionImpl

public class ProcessingInstructionImpl
extends CharacterDataImpl
implements org.w3c.dom.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.

# INTERNAL:

  Usage of this class is not supported. It may be altered or removed at any time.

  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.
  Specified by:
    `getNodeType` in interface `org.w3c.dom.Node`
  Overrides:
    `getNodeType` in class `NodeImpl`

### getNodeName

    public java.lang.String getNodeName()

  Returns the target
  Specified by:
    `getNodeName` in interface `org.w3c.dom.Node`
  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 `org.w3c.dom.ProcessingInstruction`

### getBaseURI

    public java.lang.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 `org.w3c.dom.Node`
  Overrides:
    `getBaseURI` in class `NodeImpl`
  Returns:
    The absolute base URI of this node or null.
  Since:
    DOM Level 3
