Enum Class Opcode

java.lang.Object

java.lang.Enum<Opcode>

java.lang.classfile.Opcode

All Implemented Interfaces:: Serializable,Comparable<Opcode>,Constable

public enumOpcodeextendsEnum<Opcode>

Describes the opcodes of the JVM instruction set, as described in JVMS6.5.This includes a few pseudo-opcodes modified bywide.

An opcode describes the operation of an instruction.

API Note:

The enum constants are named after the opcodes' mnemonics in uppercase.Wide pseudo-opcodes are named with the original opcodes' mnemonic plusa_W suffix. However,ldc_w,ldc2_w,goto_w, andjsr_w are legitimate opcodesinstead of wide pseudo-opcodes.

Method Details
- values
  public static Opcode[] values()
  Returns an array containing the constants of this enum class, inthe order they are declared.
  Returns:
  an array containing the constants of this enum class, in the order they are declared
- valueOf
  public static Opcode valueOf(String name)
  Returns the enum constant of this class with the specified name.The string must matchexactly an identifier used to declare anenum constant in this class. (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 class has no constant with the specified name
  NullPointerException - if the argument is null
- bytecode
  public int bytecode()
  Returns the opcode value. Forwide pseudo-opcodes, returns thefirst 2 bytes of the instruction, which are the wide opcode196 (0xC4)and the functional opcode, as a U2 value.
  Returns:
  the opcode value
- isWide
  public boolean isWide()
  Returns true if this is a pseudo-opcode modified by wide opcode.
  wide extends local variable index by additional bytes.
  Returns:
  true if this is a pseudo-opcode modified by wide opcode

- sizeIfFixed
  public int sizeIfFixed()
  Returns size of the instruction in bytes if fixed, or -1 otherwise. This size includesthe opcode itself.
  Returns:
  size of the instruction in bytes if fixed, or -1 otherwise
  See Also:
  Instruction::sizeInBytes
- kind
  public Opcode.Kind kind()
  Returns operation kind. Each kind of operation has its own modelinginterface to model instructions belonging to that kind.
  Returns:
