Methods Summary
public static Dopget(int opcode)
Gets the {@link Dop} for the given opcode value.

param
opcode {@code Opcodes.MIN_VALUE..Opcodes.MAX_VALUE;} the opcode value
return
{@code non-null;} the associated opcode instance

        int idx = opcode - Opcodes.MIN_VALUE;

        try {
            Dop result = DOPS[idx];
            if (result != null) {
                return result;
            }
        } catch (ArrayIndexOutOfBoundsException ex) {
            // Fall through.
        }

        throw new IllegalArgumentException("bogus opcode");
public static DopgetNextOrNull(Dop opcode, com.android.dx.dex.DexOptions options)
Gets the next {@link Dop} in the instruction fitting chain after the given instance, if any.

param
opcode {@code non-null;} the opcode
param
options {@code non-null;} options, used to determine which opcodes are potentially off-limits
return
{@code null-ok;} the next opcode in the same family, in the chain of opcodes to try, or {@code null} if the given opcode is the last in its chain

      int nextOpcode = opcode.getNextOpcode();

      if (nextOpcode == Opcodes.NO_NEXT) {
        return null;
      }

      opcode = get(nextOpcode);

      return opcode;
private static voidset(Dop opcode)
Puts the given opcode into the table of all ops.

param
opcode {@code non-null;} the opcode

        int idx = opcode.getOpcode() - Opcodes.MIN_VALUE;
        DOPS[idx] = opcode;
