      public UnionPattern(Pattern p1, Pattern p2)
      Constructor
      Parameters:

      p2 - the right-hand operand

  • Method Details

    • simplify

      public Pattern simplify() throws XPathException
      Simplify the pattern: perform any context-independent optimisations
      Overrides:
      simplify in class Pattern

      the optimised Pattern
      Throws:
      XPathException

    • setOriginalText

      public void setOriginalText(String pattern)
      Set the original text
      Overrides:
      setOriginalText in class Pattern

    • matches

      public boolean matches(NodeInfo e, Context c) throws XPathException
      Determine if the supplied node matches the pattern
      Specified by:
      matches in class Pattern
      Parameters:
      e - The NodeInfo representing the Element or other node to be tested against the Pattern
      c - The context in which the match is to take place. Only relevant if the pattern uses variables.
      Returns:
      true if the node matches either of the operand patterns
      Throws:
      XPathException

    • getNodeType

      public short getNodeType()

      Overrides:
      getNodeType in class Pattern
      Returns:
      the type of node matched by this pattern. e.g. Node.ELEMENT or Node.TEXT

      public Pattern getLHS()
      Get the LHS of the union

    • getRHS

      public Pattern getRHS()
      Get the RHS of the union
