Package javax.el

Class ELUtil

java.lang.Object

javax.el.ELUtil

class ELUtil
extends Object

Utility methods for this portion of the EL implementation

Methods on this class use a Map instance stored in ThreadLocal storage to minimize the performance impact on operations that take place multiple times on a single Thread. The keys and values of the Map are implementation private.

Replace the Map with the argument context.

Parameters:

context - the Map to be stored in ThreadLocal storage.
