Method Detail

getProxyFactoryFactory

public ProxyFactoryFactory getProxyFactoryFactory()

Description copied from interface: BytecodeProvider

Retrieve the specific factory for this provider capable of generating run-time proxies for lazy-loading purposes.

Specified by:

getProxyFactoryFactory in interface BytecodeProvider

Returns:

The provider specific factory.

getReflectionOptimizer

public ReflectionOptimizer getReflectionOptimizer(Class clazz,
                                                  String[] getterNames,
                                                  String[] setterNames,
                                                  Class[] types)

Description copied from interface: BytecodeProvider

Retrieve the ReflectionOptimizer delegate for this provider capable of generating reflection optimization components.

Specified by:

getReflectionOptimizer in interface BytecodeProvider

Parameters:

clazz - The class to be reflected upon.

getterNames - Names of all property getters to be accessed via reflection.

setterNames - Names of all property setters to be accessed via reflection.

types - The types of all properties to be accessed.

Returns:

The reflection optimization delegate.

getByteBuddyProxyHelper

public ByteBuddyProxyHelper getByteBuddyProxyHelper()

getEnhancer

public Enhancer getEnhancer(EnhancementContext enhancementContext)

Description copied from interface: BytecodeProvider

Returns a byte code enhancer that implements the enhancements described in the supplied enhancement context.

Specified by:

getEnhancer in interface BytecodeProvider

Parameters:

enhancementContext - The enhancement context that describes the enhancements to apply.

Returns:

An enhancer to perform byte code manipulations.

resetCaches

public void resetCaches()

Description copied from interface: BytecodeProvider

Some BytecodeProvider implementations will have classloader specific caching. These caches are useful at runtime but need to be reset at least on SessionFactory shutdown to prevent leaking the deployment classloader. Since the BytecodeProvider is static these caches are potentially shared across multiple deployments; in this case we'll clear all caches which might show as a small, temporary performance degradation on the SessionFactory instances which haven't been closed. This limitation will be removed in the future, when these providers will no longer be static.

Specified by:

resetCaches in interface BytecodeProvider
