Class DecodedInstruction

  • public class DecodedInstruction
extends java.lang.Object
    A decoded, but not yet disassembled instruction. Basic unit is a byte. Instruction image is an int stored in big-endian.

        string - the string which the recognized variant returned
        constant - the constant obtained from the string

      • add

        public void add​(int key,
                int bits,
                int length)
        Adds the recognized subrule-returning variant to the instruction.
        Parameters:
        key - the rule code
        bits - the bit sequence in little-endian, padded to whole bytes
        length - bit length (in bits)

      • hasKey

        public boolean hasKey​(int key)
        Returns true if the instruction contains the specified key.
        Parameters:
        key - the rule code
