Interface ELContextFactory

All Known Implementing Classes:

DefaultElContextFactory

public interface ELContextFactory

A factory for creating a EL context object that will be used to evaluate a target object of an EL expression. Note this ELContextFactory is not used at parse time, only evaluation time. Therefore, factories should not be concerned with setting up parse-time context attributes such as the variable mapper and function mapper that play no part during expression evaluation.
