org.hibernate.bytecode
Interface BytecodeProvider

All Known Implementing Classes:: BytecodeProviderImpl, BytecodeProviderImpl

public interface BytecodeProvider

Contract for providers of bytecode services to Hibernate.

Bytecode requirements break down into basically 3 areas

proxy generation (both for runtime-lazy-loading and basic proxy generation) getProxyFactoryFactory()
bean relection optimization getReflectionOptimizer(java.lang.Class, java.lang.String[], java.lang.String[], java.lang.Class[])
field-access instumentation getTransformer(org.hibernate.bytecode.util.ClassFilter, org.hibernate.bytecode.util.FieldFilter)

Author:: Steve Ebersole

Method Summary

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

ReflectionOptimizer getReflectionOptimizer(Class clazz, String[] getterNames, String[] setterNames, Class[] types)
          Retrieve the ReflectionOptimizer delegate for this provider capable of generating reflection optimization components.

ClassTransformer getTransformer(ClassFilter classFilter, FieldFilter fieldFilter)
          Generate a ClassTransformer capable of performing bytecode manipulation.

Method Detail

getProxyFactoryFactory

public ProxyFactoryFactory getProxyFactoryFactory()

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

Returns:: The provider specifc factory.

getReflectionOptimizer

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

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

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.

getTransformer

public ClassTransformer getTransformer(ClassFilter classFilter,
                                       FieldFilter fieldFilter)

Generate a ClassTransformer capable of performing bytecode manipulation.

Parameters:: classFilter - filter used to limit which classes are to be instrumented via this ClassTransformer.; fieldFilter - filter used to limit which fields are to be instrumented via this ClassTransformer.
Returns:: The appropriate ClassTransformer.
