Enum VectorShape

java.lang.Object

java.lang.Enum<VectorShape>

jdk.incubator.vector.VectorShape

All Implemented Interfaces:

Serializable, Comparable<VectorShape>, Constable

public enum VectorShape
extends Enum<VectorShape>

A VectorShape governs the total size, in bits, of a Vector, VectorMask, or VectorShuffle. The shape in combination with the element type together govern the number of lanes.

Method Detail

values

public static VectorShape[] values()

Returns an array containing the constants of this enum type, in the order they are declared.

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static VectorShape valueOf(String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum type has no constant with the specified name

NullPointerException - if the argument is null

bitSize

public int bitSize()

Returns the size, in bits, of this shape.

Returns:

the size, in bits, of this shape.

forBitSize

public static VectorShape forBitSize(int bitSize)

Finds appropriate shape depending on bitsize.

Parameters:

bitSize - the size in bits

Returns:

the shape corresponding to bitsize
