## org.apache.xerces.dom
Class ProcessingInstructionImpl

    java.lang.Object
      org.apache.xerces.dom.NodeImpl
          org.apache.xerces.dom.ChildNode
              org.apache.xerces.dom.CharacterDataImpl
                  org.apache.xerces.dom.ProcessingInstructionImpl

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

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.

Since:
  PR-DOM-Level-1-19980818.

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.

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

### getNodeName

    public java.lang.String getNodeName()

  Returns the target

  Specified by:
    `getNodeName` in interface `org.w3c.dom.Node`
  Specified by:
    `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`

### 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 `org.w3c.dom.ProcessingInstruction`
  Overrides:
    `getData` in class `CharacterDataImpl`

### 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 `org.w3c.dom.ProcessingInstruction`
  Overrides:
    `setData` in class `CharacterDataImpl`
  Throws:
    `DOMException(NO_MODIFICATION_ALLOWED_ERR)` - if node is read-only.
  See Also:
    `getData().`

### 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
