Class AgentBuilder.BinaryLocator.WithTypePoolCache

java.lang.Object

net.bytebuddy.agent.builder.AgentBuilder.BinaryLocator.WithTypePoolCache

All Implemented Interfaces:

AgentBuilder.BinaryLocator

Direct Known Subclasses:

AgentBuilder.BinaryLocator.WithTypePoolCache.Simple

Enclosing interface:

AgentBuilder.BinaryLocator

public abstract static class AgentBuilder.BinaryLocator.WithTypePoolCache
extends Object
implements AgentBuilder.BinaryLocator

A binary locator that uses type pools but allows for the configuration of a custom cache provider by class loader. Note that a TypePool can grow in size and that a static reference is kept to this pool by Byte Buddy's registration of a ClassFileTransformer what can cause a memory leak if the supplied caches are not cleared on a regular basis. Also note that a cache provider can be accessed concurrently by multiple ClassLoaders.
