java.lang.Object
   org.apache.xpath.Expression
      org.apache.xpath.patterns.UnionPattern

UnionPattern
public class UnionPattern extends Expression (Code)
This class represents a union pattern, which can have multiple individual StepPattern patterns.

Inner Class :class UnionPathPartOwner implements ExpressionOwner

Field Summary
final static  longserialVersionUID
    


Method Summary
public  voidcallVisitors(ExpressionOwner owner, XPathVisitor visitor)
    
public  booleancanTraverseOutsideSubtree()
     Tell if this expression or it's subexpressions can traverse outside the current subtree.
public  booleandeepEquals(Expression expr)
    
public  XObjectexecute(XPathContext xctxt)
     Test a node to see if it matches any of the patterns in the union.
Parameters:
  xctxt - XPath runtime context.
public  voidfixupVariables(java.util.Vector vars, int globalsSize)
     No arguments to process, so this does nothing.
public  StepPattern[]getPatterns()
     Get the contained step patterns to be tested.
public  voidsetPatterns(StepPattern[] patterns)
     Set the contained step patterns to be tested.
