Class DefaultPattern

java.lang.Object
org.dom4j.rule.pattern.DefaultPattern
All Implemented Interfaces:
NodeFilter, Pattern

public class DefaultPattern extends Object implements Pattern

DefaultPattern a default implementation of Pattern which can take any XPath implementation or NodeFilter for defining the pattern. WARNING this implementation causes a worst case, brute force XSLT rule evaluation to be performed. Wherever possible the methods getPriority(), getMatchType()and getMatchesNodeName()should be overloaded to allow more rule filtering to occur.

  • Method Details

    • matches

      public boolean matches(Node node)
      Description copied from interface: Pattern
      DOCUMENT ME!
      Specified by:
      matches in interface NodeFilter
      Specified by:
      matches in interface Pattern
      Parameters:
      node - DOCUMENT ME!
      Returns:
      true if the pattern matches the given DOM4J node.
    • getPriority

      public double getPriority()
      Description copied from interface: Pattern
      Returns the default resolution policy of the pattern according to the XSLT conflict resolution spec .
      Specified by:
      getPriority in interface Pattern
      Returns:
      DOCUMENT ME!
    • getUnionPatterns

      public Pattern[] getUnionPatterns()
      Description copied from interface: Pattern
      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.
      Specified by:
      getUnionPatterns in interface Pattern
      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()
      Description copied from interface: Pattern
      DOCUMENT ME!
      Specified by:
      getMatchType in interface Pattern
      Returns:
      the type of node the pattern matches which by default should return ANY_NODE if it can match any kind of node.
    • getMatchesNodeName

      public String getMatchesNodeName()
      Description copied from interface: Pattern
      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.
      Specified by:
      getMatchesNodeName in interface Pattern
      Returns:
      the name of the element or attribute this pattern matches or null if this pattern matches any or more than one name.
