setCallbackThreadInitializer

static CallbackThreadInitializer setCallbackThreadInitializer(Callback cb,
 CallbackThreadInitializer initializer)

Parameter:

cb - The Callback instance

initializer - The CallbackThreadInitializer - if null then the associated initializer instance is removed

Gibt zurück:

The previous initializer instance (may be null)

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.

Löst aus:

IllegalStateException - if the given pointer has already been mapped to a callback of a different type.

findCallbackClass

static Class<?> findCallbackClass(Class<?> type)

getTrampoline

public Pointer getTrampoline()

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

close

public void close()

Free native resources associated with this callback.

Angegeben von:

close in Schnittstelle AutoCloseable

close in Schnittstelle Closeable

dispose

@Deprecated
protected void dispose()

Veraltet.

disposeAll

static void disposeAll()

Dispose of all memory allocated for callbacks.

getFunctionPointer

public static Pointer getFunctionPointer(Callback cb)

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