Method Detail

evaluate

public final java.lang.Object evaluate(IExpressionContext context,

                                       StandardExpressionExecutionContext expContext)

Description copied from interface: IStandardVariableExpressionEvaluator

Evaluate the variable expression.

Specified by:

evaluate in interface IStandardVariableExpressionEvaluator

Parameters:

context - the context object.

expression - the standard variable expression to be evaluated.

expContext - the expression execution context to be applied (preprocessing, etc.)

Returns:

the result of evaluating the expression.
