org.aspectj.weaver.tools.cache

public Interface CacheBacking

Known Direct Implementers
org.aspectj.weaver.tools.cache.AbstractCacheBacking
Interface for the backing to the cache; usually a file, but could be an in-memory backing for testing.

aspectj and jvmti provide no suitable guarantees on locking for class redefinitions, so every implementation must have a some locking mechanism to prevent invalid reads.
