Enum Class InstructionFormat

java.lang.Object
java.lang.Enum<InstructionFormat>
mars.mips.instructions.InstructionFormat
All Implemented Interfaces:
Serializable, Comparable<InstructionFormat>, Constable
public enum InstructionFormat extends Enum<InstructionFormat>
These are the MIPS-defined formats of basic machine instructions. The R-format indicates the instruction works only with registers. The I-format indicates the instruction works with an immediate value (e.g. constant). The J-format indicates this is a Jump instruction. The I-branch-format is defined by me, not MIPS, to to indicate this is a Branch instruction, specifically to distinguish immediate values used as target addresses.

    • values

      public static InstructionFormat[] values()
      Returns an array containing the constants of this enum class, in the order they are declared.
      Returns:
      an array containing the constants of this enum class, in the order they are declared

    • valueOf

      public static InstructionFormat valueOf(String name)
      Returns the enum constant of this class with the specified name. The string must match exactly an identifier used to declare an enum 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
