Class AgentCachingPoolStrategy

java.lang.Object

io.opentelemetry.javaagent.tooling.muzzle.AgentCachingPoolStrategy

All Implemented Interfaces:

net.bytebuddy.agent.builder.AgentBuilder.PoolStrategy

public class AgentCachingPoolStrategy
extends Object
implements net.bytebuddy.agent.builder.AgentBuilder.PoolStrategy

There two core parts to the cache...
• a cache of ClassLoader to WeakReference<ClassLoader>
• a single cache of TypeResolutions for all ClassLoaders - keyed by a custom composite key of ClassLoader and class name

This design was chosen to create a single limited size cache that can be adjusted for the entire application -- without having to create a large number of WeakReference objects.

Eviction is handled through a size restriction
