public class MethodClosureUPP

extends Object

A MethodClosure is a thunk which enables a shared library to call into Java.
A MethodClosureUPP is a special case of MethodClosure where the C code is expecting to call a UniversalProcPtr (i.e. 68K code) instead of a regular function pointer.

Constructor Detail

MethodClosureUPP

protected MethodClosureUPP(Object targetObject,
                           String methodName,
                           String methodSignature,
                           int procInfo)

Deprecated.

Constructs a closure thunk that C code can call to invoke a particular method on a particular object. The closure allocates a small block of memory in the application's MacOS heap. The closure also maintains a reference to targetObject to prevent it from being garbage collected.

Parameters:

targetObject - the object whose method will be called (cannot be this).

methodName - the name of the method to be called

methodSignature - the signature (e.g. "(II)V") of the method to be called

Method Detail

dispose

public void dispose()

Deprecated.

You must maintain a reference to this object and call the dispose method when you want the closure thunk in the app's heap to be freed.

getProc

public int getProc()

Deprecated.

Returns a UniversalProcPtr

Returns:

an int which can be passed to a shared library and cast to a C UniversalProcPtr
