Enum Class DType

java.lang.Object
java.lang.Enum<DType>
uk.ac.manchester.tornado.api.types.tensors.DType
All Implemented Interfaces:
Serializable, Comparable<DType>, Constable
public enum DType extends Enum<DType>
DType relies on preview features of the Java platform:
  • DType refers to one or more preview APIs: ValueLayout.
Programs can only use DType when preview features are enabled.
Preview features may be removed in a future release, or upgraded to permanent features of the Java platform.
The DType enum represents the various data types can be found in models.
