    • matches

      public abstract boolean matches(Object node, Context context) throws JaxenException
      Parameters:
      node - ????
      context - ????
      Returns:
      true if the pattern matches the given node
      Throws:
      JaxenException - if ????

    • getPriority

      public double getPriority()
      Returns the default resolution policy of the pattern according to the XSLT conflict resolution rules.
      Returns:
      0.5; the default priority defined in XSLT
      See Also:

    • getUnionPatterns

      public Pattern[] getUnionPatterns()
      If this pattern is a union pattern then this method should return an array of patterns which describe the union pattern, which should contain more than one pattern. Otherwise this method should return null.
      Returns:
      an array of the patterns which make up this union pattern or null if this pattern is not a union pattern

    • getMatchType

      public short getMatchType()
      Returns the type of node the pattern matches.
      Returns:
      ANY_NODE unless overridden

    • getMatchesNodeName

      public String getMatchesNodeName()
      For patterns which only match an ATTRIBUTE_NODE or an ELEMENT_NODE then this pattern may return the name of the element or attribute it matches. This allows a more efficient rule matching algorithm to be performed, rather than a brute force approach of evaluating every pattern for a given Node.
      Returns:
      the name of the element or attribute this pattern matches or null if this pattern matches any or more than one name

    • simplify

      public Pattern simplify()

    • getText

      public abstract String getText()
      Returns a textual representation of this pattern
      Returns:
      the usual string form of this XSLT pattern
