Constructor Detail

OptimizedObjectInputStream

public OptimizedObjectInputStream(InputStream is)
                           throws IOException

Creates a new instance of MarshalledValueOutputStream

Method Detail

useClassCache

public static void useClassCache(boolean flag)

Enable local caching of resolved proxy classes. This can only be used if there is a single ULR and no redeployment of the proxy classes.

Parameters:: flag - true to enable caching, false to disable it

flushClassCache

public static void flushClassCache()

Clear the current proxy cache.

lookup

protected static ObjectStreamClass lookup(Class clazz)

readClassDescriptor

                      throws IOException,
                             ClassNotFoundException

Use the thread context class loader to resolve the class

Throws:: IOException - Any exception thrown by the underlying OutputStream.; ClassNotFoundException

resolveProxyClass

protected Class resolveProxyClass(String[] interfaces)
                           throws IOException,
