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

param
opcode DalvOps.MIN_VALUE..DalvOps.MAX_VALUE; the opcode value
return
non-null; the associated opcode instance

        int idx = opcode - DalvOps.MIN_VALUE;

        } catch (ArrayIndexOutOfBoundsException ex) {
            // 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 DalvOps.MIN_VALUE..DalvOps.MAX_VALUE; the opcode family
param
format non-null; the opcode's instruction format
return
null-ok; the corresponding opcode, or null if there is none

        if (format == null) {

        }

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

param
opcode non-null; the opcode

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