in interfaceBinaryExpr
- Returns:
- the operator for the expression
-
toString

evaluate
Deprecated.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:
JaxenException
-
getLHS
Description copied from interface:BinaryExpr
Returns the left-hand side of the binary expression.- Specified by:
getLHS
in interfaceBinaryExpr
- Returns:
- the left hand side expression
-
getRHS
Description copied from interface:BinaryExpr
Returns the right-hand side of the binary expression.- Specified by:
getRHS
in interfaceBinaryExpr
- Returns:
- the right-hand side expression
-
setLHS
-
setRHS
-
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
