Class VectorHalf

java.lang.Object

uk.ac.manchester.tornado.api.types.collections.VectorHalf

All Implemented Interfaces:

Serializable, TornadoCollectionInterface<ShortBuffer>, PrimitiveStorage<ShortBuffer>

public final class VectorHalf
extends Object
implements TornadoCollectionInterface<ShortBuffer>

VectorHalf relies on preview features of the Java platform:

• VectorHalf refers to one or more preview APIs: MemorySegment.

Programs can only use VectorHalf when preview features are enabled.

Preview features may be removed in a future release, or upgraded to permanent features of the Java platform.
