Class Source

java.lang.Object

org.apache.commons.jexl3.internal.Source

All Implemented Interfaces:

java.lang.Comparable<Source>

public final class Source
extends java.lang.Object
implements java.lang.Comparable<Source>

Maintains the set of allowed features associated with a script/expression source.

This is meant for caching scripts using their 'source' as key but still distinguishing scripts with different features and prevent false sharing.
