Dop

• java.lang.Object

Fields Summary
private final int	opcode DalvOps.MIN_VALUE..DalvOps.MAX_VALUE; the opcode value itself
private final int	family DalvOps.MIN_VALUE..DalvOps.MAX_VALUE; the opcode family
private final InsnFormat	format non-null; the instruction format
private final boolean	hasResult whether this opcode uses a result register
private final String	name non-null; the name

Constructors Summary

public Dop(int opcode, int family, InsnFormat format, boolean hasResult, String name) Constructs an instance. param opcode DalvOps.MIN_VALUE..DalvOps.MAX_VALUE; the opcode value itself param family DalvOps.MIN_VALUE..DalvOps.MAX_VALUE; the opcode family param format non-null; the instruction format param hasResult whether the opcode has a result register; if so it is always the first register param name non-null; the name if ((opcode < DalvOps.MIN_VALUE) || (opcode > DalvOps.MAX_VALUE)) { throw new IllegalArgumentException("bogus opcode"); } if ((family < DalvOps.MIN_VALUE) || (family > DalvOps.MAX_VALUE)) { throw new IllegalArgumentException("bogus family"); } if (format == null) { throw new NullPointerException("format == null"); } if (name == null) { throw new NullPointerException("name == null"); } this.opcode = opcode; this.family = family; this.format = format; this.hasResult = hasResult; this.name = name;

Methods Summary
public int	getFamily() Gets the opcode family. The opcode family is the unmarked (no "/...") opcode that has equivalent semantics to this one. return DalvOps.MIN_VALUE..DalvOps.MAX_VALUE; the opcode family return family;
public InsnFormat	getFormat() Gets the instruction format. return non-null; the instruction format return format;
public java.lang.String	getName() Gets the opcode name. return non-null; the opcode name return name;
public int	getOpcode() Gets the opcode value. return DalvOps.MIN_VALUE..DalvOps.MAX_VALUE; the opcode value return opcode;
public com.android.dx.dex.code.Dop	getOppositeTest() Gets the opcode for the opposite test of this instance. This is only valid for opcodes which are in fact tests. return non-null; the opposite test switch (opcode) { case DalvOps.IF_EQ: return Dops.IF_NE; case DalvOps.IF_NE: return Dops.IF_EQ; case DalvOps.IF_LT: return Dops.IF_GE; case DalvOps.IF_GE: return Dops.IF_LT; case DalvOps.IF_GT: return Dops.IF_LE; case DalvOps.IF_LE: return Dops.IF_GT; case DalvOps.IF_EQZ: return Dops.IF_NEZ; case DalvOps.IF_NEZ: return Dops.IF_EQZ; case DalvOps.IF_LTZ: return Dops.IF_GEZ; case DalvOps.IF_GEZ: return Dops.IF_LTZ; case DalvOps.IF_GTZ: return Dops.IF_LEZ; case DalvOps.IF_LEZ: return Dops.IF_GTZ; } throw new IllegalArgumentException("bogus opcode: " + this);
public boolean	hasResult() Returns whether this opcode uses a result register. return true iff this opcode uses a result register return hasResult;
public java.lang.String	toString() {@inheritDoc} return name;
