TargetInsn

• java.lang.Object
  • FixedSizeInsn

Fields Summary
private CodeAddress	target non-null; the branch target

Constructors Summary

public TargetInsn(Dop opcode, com.android.dx.rop.code.SourcePosition position, com.android.dx.rop.code.RegisterSpecList registers, CodeAddress target) Constructs an instance. The output address of this instance is initially unknown (-1), and the target is initially null. param opcode the opcode; one of the constants from {@link Dops} param position non-null; source position param registers non-null; register list, including a result register if appropriate (that is, registers may be either ins or outs) param target non-null; the branch target super(opcode, position, registers); if (target == null) { throw new NullPointerException("target == null"); } this.target = target;

Methods Summary
protected java.lang.String	argString() {@inheritDoc} if (target == null) { return "????"; } return target.identifierString();
public CodeAddress	getTarget() Gets the unique branch target of this instruction. return non-null; the branch target return target;
public int	getTargetAddress() Gets the target address of this instruction. This is only valid to call if the target instruction has been assigned an address, and it is merely a convenient shorthand for getTarget().getAddress(). return >= 0; the target address return target.getAddress();
public int	getTargetOffset() Gets the branch offset of this instruction. This is only valid to call if both this and the target instruction each has been assigned an address, and it is merely a convenient shorthand for getTargetAddress() - getAddress(). return the branch offset return target.getAddress() - getAddress();
public boolean	hasTargetOffset() Returns whether the target offset is known. return true if the target offset is known or false if not return hasAddress() && target.hasAddress();
public com.android.dx.dex.code.TargetInsn	withNewTargetAndReversed(CodeAddress target) Returns an instance that is just like this one, except that its opcode has the opposite sense (as a test; e.g. a lt test becomes a ge), and its branch target is replaced by the one given, and all set-once values associated with the class (such as its address) are reset. param target non-null; the new branch target return non-null; an appropriately-constructed instance Dop opcode = getOpcode().getOppositeTest(); return new TargetInsn(opcode, getPosition(), getRegisters(), target);
public DalvInsn	withOpcode(Dop opcode) {@inheritDoc} return new TargetInsn(opcode, getPosition(), getRegisters(), target);
public DalvInsn	withRegisters(com.android.dx.rop.code.RegisterSpecList registers) {@inheritDoc} return new TargetInsn(getOpcode(), getPosition(), registers, target);
