Method Detail

getCallback

public static Callback getCallback(java.lang.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.

findCallbackClass

static java.lang.Class findCallbackClass(java.lang.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.

getTrampoline

public Pointer getTrampoline()

Obtain a pointer to the native glue code for this callback.

finalize

protected void finalize()

Free native resources associated with this callback.

Overrides:

finalize in class java.lang.Object

getFunctionPointer

public static Pointer getFunctionPointer(Callback cb)

Return a Pointer to the native function address for the given callback.
