- public class ExternalArrayPointer
- extends Pointer
A pointer to an array returned from the native code.
Use this pointer when the returned array size is not known before the
native code returns.
Memory allocated to this array is considered external
and therefore cannot be reallocated and will not be freed by JNIWrapper.
If passed array is correctly reallocated by the caller use ResizingPointer
instead of this class.
- Since:
- 1.1
