Method Details

mallocNativeStruct

protected long mallocNativeStruct() throws java.lang.OutOfMemoryError

Specified by:

mallocNativeStruct in class NativeStruct

Throws:

java.lang.OutOfMemoryError

setRng

public void setRng(Rng rng)

releaseNativeStruct

public void releaseNativeStruct()

Description copied from class: NativeStruct

Releases the host data stored in a NativeStruct. This method provides a way to release host data without depending on the garbage collector to get around to releasing it. Derived objects whose native data structures have their own free functions, should be override this method to call that function.

Overrides:
