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

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

        int idx = opcode - DalvOps.MIN_VALUE;

            // Fall through.
        }

        throw new IllegalArgumentException("bogus opcode");
public static DopgetOrNull(int family, InsnFormat format)
Gets the {@link Dop} with the given family/format combination, if any.

param
family {@code DalvOps.MIN_VALUE..DalvOps.MAX_VALUE;} the opcode family
param
format {@code non-null;} the opcode's instruction format
return
{@code null-ok;} the corresponding opcode, or {@code null} if there is none
