getFilterExpr
Description copied from interface:PathExpr
Returns the filter expression that starts the path expression.- Specified by:
getFilterExpr
in interfacePathExpr
- Returns:
- the filter expression that starts the path expression
-
setFilterExpr
Description copied from interface:PathExpr
Changes the expression's filter expression.- Specified by:
setFilterExpr
in interfacePathExpr
- Parameters:
filterExpr
- the new filter expression
-
getLocationPath
Description copied from interface:PathExpr
Returns the location path part of this path expression.- Specified by:
getLocationPath
in interfacePathExpr
- Returns:
- the location path part of this expression
-
toString
-
getText
Description copied from interface:Expr
Returns a String containing the XPath expression. -
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 interfaceExpr
- Overrides:
simplify
in classDefaultExpr
- Returns:
- the simplified expression
-
evaluate
Description copied from interface:Expr
Evaluate the expression in the given context, and return the result. The result will be ajava.lang.Double
for expressions that return a number, ajava.lang.String
for expressions that return a string, ajava.lang.Boolean
for expressions that return a boolean, and ajava.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 interfaceExpr
- Parameters:
context
- the context in which the expression is evaluated- Returns:
- an object representing the result of the evaluation
- Throws:
