Class Cache

java.lang.Object

org.opencds.cqf.cql.engine.execution.Cache

public class Cache
extends Object

There are at least two types of data that need to be cached, some that is context dependent, like expression results (and thus can be invalidated during the course of evaluation) and some that is not, like Function resolutions (and thus can be cache for the entire duration of the evaluation).
