      public Expr getFilterExpr()
      Description copied from interface: PathExpr
      Returns the filter expression that starts the path expression.
      Specified by:
      getFilterExpr in interface PathExpr
      Returns:
      the filter expression that starts the path expression
    • setFilterExpr

      public void setFilterExpr(Expr filterExpr)
      Description copied from interface: PathExpr
      Changes the expression's filter expression.
      Specified by:
      setFilterExpr in interface PathExpr
      Parameters:
      filterExpr - the new filter expression
    • getLocationPath

      public LocationPath getLocationPath()
      Description copied from interface: PathExpr
      Returns the location path part of this path expression.
      Specified by:
      getLocationPath in interface PathExpr
      Returns:
      the location path part of this expression
    • toString

      public String toString()
      Overrides:
      toString in class Object
    • getText

      public String getText()
      Description copied from interface: Expr
      Returns a String containing the XPath expression.
      Specified by:
      getText in interface Expr
      Returns:
      the text form of this XPath expression
    • simplify

      public Expr simplify()
      Description copied from interface: Expr
      Simplifies the XPath expression. For example, the expression //para[1 = 1] could be simplified to //para. In practice, this is usually a noop. Jaxen does not currently perform any simplification.
      Specified by:
      simplify in interface Expr
      Overrides:
      simplify in class DefaultExpr
      Returns:
      the simplified expression
    • evaluate

      public Object evaluate(Context context) throws JaxenException
      Description copied from interface: Expr
      Evaluate the expression in the given context, and return the result. The result will be a java.lang.Double for expressions that return a number, a java.lang.String for expressions that return a string, a java.lang.Boolean for expressions that return a boolean, and a java.util.List for expressions that return a node-set. In the latter case, the elements of the list are the actual objects from the source document model. Copies are not made.
      Specified by:
      evaluate in interface Expr
      Parameters:
      context - the context in which the expression is evaluated
      Returns:
      an object representing the result of the evaluation
      Throws:
      JaxenException
