Class ProxyFactory

public class ProxyFactory extends java.lang.Object
Factory of dynamic proxy classes.This factory generates a class that extends the given super class and implements the given interfaces. The calls of the methods inherited from the super class are forwarded and then
invoke()
is called on the method handler associated with instances of the generated class. The calls of the methods from the interfaces are also forwarded to the method handler.For example, if the following code is executed,
ProxyFactory f = new ProxyFactory(); f.setSuperclass(Foo.class); f.setFilter(new MethodFilter() { public boolean isHandled(Method m) { // ignore finalize() return !m.getName().equals("finalize"); } }); Class c = f.createClass(); MethodHandler mi = new MethodHandler() { public Object invoke(Object self, Method m, Method proceed, Object[] args) throws Throwable { System.out.println("Name: " + m.getName()); return proceed.invoke(self, args); // execute the original method. } }; Foo foo = (Foo)c.newInstance(); ((Proxy)foo).setHandler(mi);
Here,
Method
isjava.lang.reflect.Method
.Then, the following method call will be forwarded to MethodHandler
mi
and prints a message before executing the originally called methodbar()
inFoo
.foo.bar();
The last three lines of the code shown above can be replaced with a call to the helper method
create
, which generates a proxy class, instantiates it, and sets the method handler of the instance:: Foo foo = (Foo)f.create(new Class[0], new Object[0], mi);
To change the method handler during runtime, execute the following code:
MethodHandler mi = ... ; // alternative handler ((Proxy)foo).setHandler(mi);
If setHandler is never called for a proxy instance then it will employ the default handler which proceeds by invoking the original method. The behaviour of the default handler is identical to the following handler:
class EmptyHandler implements MethodHandler { public Object invoke(Object self, Method m, Method proceed, Object[] args) throws Exception { return proceed.invoke(self, args); } }
A proxy factory caches and reuses proxy classes by default. It is possible to reset this default globally by setting static field
useCache
to false. Caching may also be configured for a specific factory by calling instance methodsetUseCache(boolean)
. It is strongly recommended that new clients of class ProxyFactory enable caching. Failure to do so may lead to exhaustion of the heap memory area used to store classes.Caching is automatically disabled for any given proxy factory if deprecated instance method
setHandler(MethodHandler)
is called. This method was used to specify a default handler which newly created proxy classes should install when they create their instances. It is only retained to provide backward compatibility with previous releases of javassist. Unfortunately,this legacy behaviour makes caching and reuse of proxy classes impossible. The current programming model expects javassist clients to set the handler of a proxy instance explicitly by calling methodProxy.setHandler(MethodHandler)
as shown in the sample code above. New clients are strongly recommended to use this model rather than callingsetHandler(MethodHandler)
.A proxy object generated by
ProxyFactory
is serializable if its super class or any of its interfaces implementjava.io.Serializable
. However, a serialized proxy object may not be compatible with future releases. The serialization support should be used for short-term storage or RMI.For compatibility with older releases serialization of proxy objects is implemented by adding a writeReplace method to the proxy class. This allows a proxy to be serialized to a conventional
ObjectOutputStream
and deserialized from a correspondingObjectInputStream
. However this method suffers from several problems, the most notable one being that it fails to serialize state inherited from the proxy's superclass.An alternative method of serializing proxy objects is available which fixes these problems. It requires inhibiting generation of the writeReplace method and instead using instances of
ProxyObjectOutputStream
andProxyObjectInputStream
(which are subclasses ofObjectOutputStream
andObjectInputStream
) to serialize and deserialize, respectively, the proxy. These streams recognise javassist proxies and ensure that they are serialized and deserialized without the need for the proxy class to implement special methods such as writeReplace. Generation of the writeReplace method can be disabled globally by setting static fielduseWriteReplace
to false. Alternatively, it may be configured per factory by calling instance methodsetUseWriteReplace(boolean)

useCache
public static volatile boolean useCache
If true, a generated proxy class is cached and it will be reused when generating the proxy class with the same properties is requested. The default value is true. Note that this value merely specifies the initial setting employed by any newly created proxy factory. The factory setting may be overwritten by calling factory instance methodsetUseCache(boolean)
- Since:
- 3.4
-
useWriteReplace
public static volatile boolean useWriteReplace
If true, a generated proxy class will implement method writeReplace enabling serialization of its proxies to a conventional ObjectOutputStream. this (default) setting retains the old javassist behaviour which has the advantage that it retains compatibility with older releases and requires no extra work on the part of the client performing the serialization. However, it has the disadvantage that state inherited from the superclasses of the proxy is lost during serialization. if false then serialization/deserialization of the proxy instances will preserve all fields. However, serialization must be performed via aProxyObjectOutputStream
and deserialization must be viaProxyObjectInputStream
. Any attempt to serialize proxies whose class was created with useWriteReplace set to false via a normalObjectOutputStream
will fail. Note that this value merely specifies the initial setting employed by any newly created proxy factory. The factory setting may be overwritten by calling factory instance methodsetUseWriteReplace(boolean)
