internalAsyncMarkDelete

protected void internalAsyncMarkDelete(PositionImpl newPosition,
 Map<String,Long> properties,
 AsyncCallbacks.MarkDeleteCallback callback,
 Object ctx)

Overrides:

internalAsyncMarkDelete in class ManagedCursorImpl

asyncClose

public void asyncClose(AsyncCallbacks.CloseCallback callback,
 Object ctx)

Description copied from interface: ManagedCursor

Close the cursor asynchronously and release the associated resources.

Specified by:

asyncClose in interface ManagedCursor

Overrides:

asyncClose in class ManagedCursorImpl

Parameters:

callback - callback object

ctx - opaque context

asyncDeleteCursor
