All Implemented Interfaces:

AgentBuilder.PoolStrategy

Enclosing class:

AgentBuilder.PoolStrategy.WithTypePoolCache

@HashCodeAndEqualsPlugin.Enhance
public static class AgentBuilder.PoolStrategy.WithTypePoolCache.Simple
extends AgentBuilder.PoolStrategy.WithTypePoolCache

An implementation of a type locator AgentBuilder.PoolStrategy.WithTypePoolCache (note documentation of the linked class) that is based on a ConcurrentMap. It is the responsibility of the type locator's user to avoid the type locator from leaking memory.

Constructor Detail

Simple

public Simple(ConcurrentMap<? super ClassLoader,TypePool.CacheProvider> cacheProviders)

Creates a new type locator that caches a cache provider per class loader in a concurrent map. The type locator uses a fast TypePool.Default.ReaderMode.

Parameters:

cacheProviders - The concurrent map that is used for storing a cache provider per class loader.

Simple

public Simple(TypePool.Default.ReaderMode readerMode,
              ConcurrentMap<? super ClassLoader,TypePool.CacheProvider> cacheProviders)

Creates a new type locator that caches a cache provider per class loader in a concurrent map.

Parameters:

readerMode - The reader mode to use for parsing a class file.

cacheProviders - The concurrent map that is used for storing a cache provider per class loader.

Simple

public Simple(TypePool.Default.ReaderMode readerMode,
              TypePool.Default.WithLazyResolution.LazinessMode lazinessMode,
              ConcurrentMap<? super ClassLoader,TypePool.CacheProvider> cacheProviders)

Creates a new type locator that caches a cache provider per class loader in a concurrent map.

Parameters:

readerMode - The reader mode to use for parsing a class file.

lazinessMode - The laziness mode to use for when to parse a class file.

cacheProviders - The concurrent map that is used for storing a cache provider per class loader.

Method Detail

locate

protected TypePool.CacheProvider locate(@MaybeNull
                                        ClassLoader classLoader)

Description copied from class: AgentBuilder.PoolStrategy.WithTypePoolCache

Locates a cache provider for a given class loader.

Specified by:

locate in class AgentBuilder.PoolStrategy.WithTypePoolCache

Parameters:

classLoader - The class loader for which to locate a cache. This class loader might be null to represent the bootstrap loader.

Returns:

The cache provider to use.

getBootstrapMarkerLoader

protected ClassLoader getBootstrapMarkerLoader()

Returns the class loader to serve as a cache key if a cache provider for the bootstrap class loader is requested. This class loader is represented by null in the JVM which is an invalid value for many ConcurrentMap implementations.

By default, a custom class loader is created to use as a marker.

Returns:

A class loader to represent the bootstrap class loader.
