Description copied from interface: BinaryExpr

Returns the operator for the binary expression such as "+" or "div".

Specified by:

getOperator in interface BinaryExpr

Specified by:

getOperator in class DefaultBinaryExpr

Returns:

the operator for the expression

evaluate

public java.lang.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.

Parameters:

context - the context in which the expression is evaluated

Returns:

an object representing the result of the evaluation

Throws:

JaxenException
