Field Detail

vals

private static final RegisterConstants.MM[] vals

Local copy of the backing array. Copied here to avoid calls to clone

Method Detail

values

public static RegisterConstants.MM[] 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 (RegisterConstants.MM c : RegisterConstants.MM.values())
    System.out.println(c);

Returns:

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

valueOf

public static RegisterConstants.MM 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

value

public byte value()

Specified by:

value in interface MachineRegister

Specified by:

value in interface RegisterConstants.IntelMachineRegister

Returns:

encoded value of this register

needsREXprefix

public boolean needsREXprefix()

Specified by:

needsREXprefix in interface RegisterConstants.IntelMachineRegister

Returns:

does this register require a REX prefix byte?

lookup

public static RegisterConstants.MM lookup(int num)

Convert encoded value into the MM it represents

Parameters:

num - encoded value

Returns:

represented MM
