@Enhance public abstract static class AgentBuilder.PoolStrategy.WithTypePoolCache extends java.lang.Object implements AgentBuilder.PoolStrategy
A type 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 aClassFileTransformer
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 multipleClassLoader
s.All types that are returned by the locator's type pool are resolved lazily.

- The class loader for which the class file locator was created.- Returns:
- A type pool for the supplied class file locator.
-
typePool
public TypePool typePool(ClassFileLocator classFileLocator, java.lang.ClassLoader classLoader, java.lang.String name)
