Inherited Methods

From class java.lang.Object

Object	clone() Creates and returns a copy of this object.
boolean	equals(Object obj) Indicates whether some other object is "equal to" this one.
void	finalize() Called by the garbage collector on an object when garbage collection determines that there are no more references to the object.
final Class<?>	getClass() Returns the runtime class of this `Object`.
int	hashCode() Returns a hash code value for the object.
final void	notify() Wakes up a single thread that is waiting on this object's monitor.
final void	notifyAll() Wakes up all threads that are waiting on this object's monitor.
String	toString() Returns a string representation of the object.
final void	wait() Causes the current thread to wait until another thread invokes the `notify()` method or the `notifyAll()` method for this object.
final void	wait(long timeout, int nanos) Causes the current thread to wait until another thread invokes the `notify()` method or the `notifyAll()` method for this object, or some other thread interrupts the current thread, or a certain amount of real time has elapsed.
final void	wait(long timeout) Causes the current thread to wait until either another thread invokes the `notify()` method or the `notifyAll()` method for this object, or a specified amount of time has elapsed.

Public Methods

public static long computeMethodHash (Method m)

Compute the "method hash" of a remote method. The method hash is a long containing the first 64 bits of the SHA digest from the UTF encoded string of the method name and descriptor.

public static Remote createProxy (Class implClass, RemoteRef clientRef, boolean forceStubUse)

Returns a proxy for the specified implClass. If both of the following criteria is satisfied, a dynamic proxy for the specified implClass is returned (otherwise a RemoteStub instance for the specified implClass is returned): a) either the property java.rmi.server.ignoreStubClasses is true or a pregenerated stub class does not exist for the impl class, and b) forceStubUse is false. If the above criteria are satisfied, this method constructs a dynamic proxy instance (that implements the remote interfaces of implClass) constructed with a RemoteObjectInvocationHandler instance constructed with the clientRef. Otherwise, this method loads the pregenerated stub class (which extends RemoteStub and implements the remote interfaces of implClass) and constructs an instance of the pregenerated stub class with the clientRef.

Parameters

implClass	the class to obtain remote interfaces from
clientRef	the remote ref to use in the invocation handler
forceStubUse	if true, forces creation of a RemoteStub

Throws

IllegalArgumentException	if implClass implements illegal remote interfaces
StubNotFoundException	if problem locating/creating stub or creating the dynamic proxy instance

public static String getUnqualifiedName (Class c)

Returns the binary name of the given type without package qualification. Nested types are treated no differently from top-level types, so for a nested type, the returned name will still be qualified with the simple name of its enclosing top-level type (and perhaps other enclosing types), the separator will be '$', etc.
