Enum Constant Detail

SignedRight

public static final ShiftMode SignedRight

The shift is to the righ with sign extension.

UnsignedRight

public static final ShiftMode UnsignedRight

The shift is to the righ with zero bit fill on the left.

Left

public static final ShiftMode Left

The shift is to the left with zero bit fill on the right.

LeftRotate

Method Detail

values

public static ShiftMode[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (ShiftMode c : ShiftMode.values())
    System.out.println(c);

Returns:

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

valueOf

public static ShiftMode valueOf(java.lang.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:

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

java.lang.NullPointerException - if the argument is null
