Field Summary

static Map allocations

static Map callbackMap

Pointer cbstruct

static Map directCallbackMap

Method method

CallbackProxy proxy

Method Summary

protected void finalize()
Free native resources associated with this callback.

static Class findCallbackClass(Class type)
Find the first instance of an interface which implements the Callback interface or an interface derived from Callback, which defines an appropriate callback method.

static Callback getCallback(Class type, Pointer p)
Return a Callback associated with the given function pointer.

static Pointer getFunctionPointer(Callback cb)
Return a Pointer to the native function address for the given callback.

Pointer getTrampoline()

finalize

protected void finalize()

Free native resources associated with this callback.

findCallbackClass

static Class findCallbackClass(Class type)

Find the first instance of an interface which implements the Callback interface or an interface derived from Callback, which defines an appropriate callback method.

getCallback

public static Callback getCallback(Class type, Pointer p)

Return a Callback associated with the given function pointer. If the pointer refers to a Java callback trampoline, return the original Java Callback. Otherwise, return a proxy to the native function pointer.

getFunctionPointer
