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
