Enum Constant Summary

Enum Constants

Enum Constant	Description
ISHL	Left shift of an int, using the low five bits of the shift count.
ISHR	Arithmetic right shift of an int, propagating the sign bit.
IUSHR	Logical right shift of an int, filling the vacated high bits with zero.
LSHL	Left shift of a long, using the low six bits of the int shift count.
LSHR	Arithmetic right shift of a long, propagating the sign bit.
LUSHR	Logical right shift of a long, filling the vacated high bits with zero.

Enum Constant Detail

ISHL

public static final ArithmeticShiftInstruction.ShiftType ISHL

Left shift of an int, using the low five bits of the shift count.

LSHL

public static final ArithmeticShiftInstruction.ShiftType LSHL

Left shift of a long, using the low six bits of the int shift count.

ISHR

public static final ArithmeticShiftInstruction.ShiftType ISHR

Arithmetic right shift of an int, propagating the sign bit.

LSHR

public static final ArithmeticShiftInstruction.ShiftType LSHR

Arithmetic right shift of a long, propagating the sign bit.

IUSHR

public static final ArithmeticShiftInstruction.ShiftType IUSHR

Logical right shift of an int, filling the vacated high bits with zero.

LUSHR

public static final ArithmeticShiftInstruction.ShiftType LUSHR

Logical right shift of a long, filling the vacated high bits with zero.

Method Detail

values

public static ArithmeticShiftInstruction.ShiftType[] 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 (ArithmeticShiftInstruction.ShiftType c : ArithmeticShiftInstruction.ShiftType.values())
    System.out.println(c);

Returns:

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

valueOf

public static ArithmeticShiftInstruction.ShiftType 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

getOpcode

public int getOpcode()

Returns:

the opcode

getMnemonic

public String getMnemonic()

Returns:

the mnemonic

fromOpcode

public static ArithmeticShiftInstruction.ShiftType fromOpcode(int opcode)

Looks up the shift type for a JVM opcode.

Parameters:

opcode - the JVM opcode

Returns:

the matching type, or null if the opcode is not a shift opcode
