Module tornado.api

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

Class VectorFloat

java.lang.Object

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

All Implemented Interfaces:

Serializable, TornadoCollectionInterface<FloatBuffer>, PrimitiveStorage<FloatBuffer>

public final class VectorFloat
extends Object
implements TornadoCollectionInterface<FloatBuffer>

VectorFloat relies on preview features of the Java platform:

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

Programs can only use VectorFloat when preview features are enabled.

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