- 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

      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.

  - ### 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`

    - #### 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.
