Dop

• java.lang.Object

Fields Summary
private final int	opcode {@code Opcodes.isValid();} the opcode value itself
private final int	family {@code Opcodes.isValid();} the opcode family
private final int	nextOpcode {@code Opcodes.isValid();} what opcode (by number) to try next when attempting to match an opcode to particular arguments; {@code Opcodes.NO_NEXT} to indicate that this is the last opcode to try in a particular chain
private final InsnFormat	format {@code non-null;} the instruction format
private final boolean	hasResult whether this opcode uses a result register

Constructors Summary

public Dop(int opcode, int family, int nextOpcode, InsnFormat format, boolean hasResult) Constructs an instance. param opcode {@code Opcodes.isValid();} the opcode value itself param family {@code Opcodes.isValid();} the opcode family param nextOpcode {@code Opcodes.isValid();} what opcode (by number) to try next when attempting to match an opcode to particular arguments; {@code Opcodes.NO_NEXT} to indicate that this is the last opcode to try in a particular chain param format {@code non-null;} the instruction format param hasResult whether the opcode has a result register; if so it is always the first register if (!Opcodes.isValidShape(opcode)) { throw new IllegalArgumentException("bogus opcode"); } if (!Opcodes.isValidShape(family)) { throw new IllegalArgumentException("bogus family"); } if (!Opcodes.isValidShape(nextOpcode)) { throw new IllegalArgumentException("bogus nextOpcode"); } if (format == null) { throw new NullPointerException("format == null"); } this.opcode = opcode; this.family = family; this.nextOpcode = nextOpcode; this.format = format; this.hasResult = hasResult;

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 {@code Opcodes.MIN_VALUE..Opcodes.MAX_VALUE;} the opcode family return family;
public InsnFormat	getFormat() Gets the instruction format. return {@code non-null;} the instruction format return format;
public java.lang.String	getName() Gets the opcode name. return {@code non-null;} the opcode name return OpcodeInfo.getName(opcode);
public int	getNextOpcode() Gets the opcode value to try next when attempting to match an opcode to particular arguments. This returns {@code Opcodes.NO_NEXT} to indicate that this is the last opcode to try in a particular chain. return {@code Opcodes.MIN_VALUE..Opcodes.MAX_VALUE;} the opcode value return nextOpcode;
public int	getOpcode() Gets the opcode value. return {@code Opcodes.MIN_VALUE..Opcodes.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 {@code non-null;} the opposite test switch (opcode) { case Opcodes.IF_EQ: return Dops.IF_NE; case Opcodes.IF_NE: return Dops.IF_EQ; case Opcodes.IF_LT: return Dops.IF_GE; case Opcodes.IF_GE: return Dops.IF_LT; case Opcodes.IF_GT: return Dops.IF_LE; case Opcodes.IF_LE: return Dops.IF_GT; case Opcodes.IF_EQZ: return Dops.IF_NEZ; case Opcodes.IF_NEZ: return Dops.IF_EQZ; case Opcodes.IF_LTZ: return Dops.IF_GEZ; case Opcodes.IF_GEZ: return Dops.IF_LTZ; case Opcodes.IF_GTZ: return Dops.IF_LEZ; case Opcodes.IF_LEZ: return Dops.IF_GTZ; } throw new IllegalArgumentException("bogus opcode: " + this);
public boolean	hasResult() Returns whether this opcode uses a result register. return {@code true} iff this opcode uses a result register return hasResult;
public java.lang.String	toString() {@inheritDoc} return getName();
