Method Detail

clearMethodClassificationCache

public static void clearMethodClassificationCache()

Method clears method classification cache that keeps direct references from proxied class methods to their implementation in the form of PredicateMethodClassification.invocationHandler. This cache speeds up method execution heavily.

clearClassCache

public static void clearClassCache()

Method clears cached classes. Please keep in mind, that classes are probably trapped in the ClassLoader and old JVMs were not able to purge non-used classes from the ClassLoader - see this answer. This cache allows reusing already generated classes for same combination of input interfaces / combination of CacheKeyProvider classifiers.

instantiate

public static <T> T instantiate(javassist.util.proxy.MethodHandler methodHandler,
                                Class<?>... interfaces)

Method creates and instantiates new proxy object with passed set of interfaces and the invocation handler. See com.fg.edee.proxy.model.traits.GenericBucketProxyGenerator#instantiateJavassistProxy(java.lang.Class) for example usage.

                                Class<?>[] interfaces,
                                Class<?>[] constructorTypes,
                                Object[] constructorArgs)

Method creates and instantiates new proxy object with passed set of interfaces and the invocation handler. See com.fg.edee.proxy.model.traits.GenericBucketProxyGenerator#instantiateJavassistProxy(java.lang.Class) for example usage.

instantiate

public static <T> T instantiate(ProxyRecipe proxyRecipe,
                                Object proxyState,
                                Class<?>[] constructorTypes,
                                Object[] constructorArgs)

Method creates and instantiates new proxy object defined by passed ProxyRecipe and uses passed `proxyState` object as proxy internal memory. The created proxy is not Serializable.

instantiate

public static <T> T instantiate(ProxyRecipe proxyRecipe,
                                Object proxyState)

Method creates and instantiates new proxy object defined by passed ProxyRecipe and uses passed `proxyState` object as proxy internal memory. The created proxy is not Serializable.

instantiateSerializable

public static <T> T instantiateSerializable(ProxyRecipe proxyRecipe,
                                            Serializable proxyState)

Method creates and instantiates new proxy object defined by passed ProxyRecipe and uses passed `proxyState` object as proxy internal memory. The created proxy is Serializable.

instantiateSerializable

public static <T> T instantiateSerializable(ProxyRecipe proxyRecipe,
                                            ProxyStateWithConstructorArgs proxyState,
                                            Class<?>[] constructorTypes,
                                            Object[] constructorArgs)

Method creates and instantiates new proxy object defined by passed ProxyRecipe and uses passed `proxyState` object as proxy internal memory. The created proxy is Serializable.

getProxyClass

public static Class<?> getProxyClass(Class<?>... interfaces)

Returns previously created class or construct new from the passed interfaces. First class of the passed class array might be abstract class. In such situation the created class will extend this proxy class. All passed interfaces will be "implemented" by the returned proxy class.
