Description copied from class: jakarta.servlet.jsp.el.Expression

Specified by:

evaluate in class Expression

Parameters:

vResolver - A VariableResolver instance that can be used at runtime to resolve the name of implicit objects into Objects.

Returns:

The result of the expression evaluation.

Throws:

ELException - Thrown if the expression evaluation failed.
