Constructor Details

BytecodeProviderImpl

public BytecodeProviderImpl()

Constructs a ByteBuddy BytecodeProvider instance which attempts to auto-detect the target JVM version from the currently running one, with a fallback on Java 11.

BytecodeProviderImpl

public BytecodeProviderImpl(net.bytebuddy.ClassFileVersion targetCompatibleJVM)

Constructs a ByteBuddy BytecodeProvider instance which aims to produce code compatible with the specified target JVM version.

Method Details

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.

getReflectionOptimizer

public @Nullable ReflectionOptimizer getReflectionOptimizer(Class<?> clazz,
 Map<String,PropertyAccess> propertyAccessMap)

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.

propertyAccessMap - The ordered property access map

Returns:

The reflection optimization delegate.

getByteBuddyProxyHelper

public ByteBuddyProxyHelper getByteBuddyProxyHelper()

getEnhancer

public @Nullable 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.

getEnhancer

public @Nullable Enhancer getEnhancer(EnhancementContext enhancementContext,
 EnhancerClassLocator classLocator)

Similar to getEnhancer(EnhancementContext) but intended for advanced users who wish to customize how ByteBuddy is locating the class files and caching the types. Possibly used in Quarkus in a future version.

Parameters:

enhancementContext -

classLocator -

Returns:

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.

resetCaches in interface BytecodeProvider
