Methods inherited from class BranchInstruction

containsTarget, dump, getIndex, getPosition, getTarget, getTargetOffset, getTargetOffset, initFromFile, setIndex, setPosition, setTarget, toString, updatePosition, updateTarget

Modifier and Type	Method	Description
boolean	containsTarget(InstructionHandle ih)	Tests whether this targeter targets the specified instruction handle.
void	dump(DataOutputStream out)	Dumps instruction as byte code to stream out.
final int	getIndex()	Gets the target offset in byte code.
protected int	getPosition()	Gets the position.
InstructionHandle	getTarget()	Gets the target of branch instruction.
protected int	getTargetOffset()	Gets the offset to this instruction's target.
protected int	getTargetOffset(InstructionHandle target)	Gets the offset to target relative to this instruction.
protected void	initFromFile(ByteSequence bytes, boolean wide)	Reads needed data (for example index) from file.
protected void	setIndex(int index)	Sets the index.
protected void	setPosition(int position)	Sets the position.
void	setTarget(InstructionHandle target)	Sets branch target.
String	toString(boolean verbose)	Long output format: <position in byte code> <name of opcode> "["<opcode number>"]" "("<length of instruction>")" "<"<target instruction>">" "@"<branch target offset>
protected int	updatePosition(int offset, int maxOffset)	Called by InstructionList.setPositions when setting the position for every instruction.
void	updateTarget(InstructionHandle oldIh, InstructionHandle newIh)	Replaces the target of this targeter from this old handle to the new handle.

Methods inherited from class Instruction

consumeStack, copy, equals, getComparator, getLength, getName, getOpcode, hashCode, isValidByte, isValidShort, produceStack, readInstruction, setComparator, toString, toString

Modifier and Type	Method	Description
int	consumeStack(ConstantPoolGen cpg)	This method also gives right results for instructions whose effect on the stack depends on the constant pool entry they reference.
Instruction	copy()	Use with caution, since 'BranchInstruction's have a 'target' reference which is not copied correctly (only basic types are).
boolean	equals(Object that)	Tests for equality, delegated to comparator
static InstructionComparator	getComparator()	Deprecated. (6.0) use the built in comparator, or wrap this class in another object that implements these methods
int	getLength()	Gets the length (in bytes) of instruction.
String	getName()	Gets the name of instruction, that is, opcode name.
short	getOpcode()	Gets this instruction's opcode.
int	hashCode()	Gets the hashCode of this object.
static boolean	isValidByte(int value)	Tests if the value can fit in a byte (signed).
static boolean	isValidShort(int value)	Tests if the value can fit in a short (signed).
int	produceStack(ConstantPoolGen cpg)	This method also gives right results for instructions whose effect on the stack depends on the constant pool entry they reference.
static Instruction	readInstruction(ByteSequence bytes)	Reads an instruction from (byte code) input stream and return the appropriate object.
static void	setComparator(InstructionComparator c)	Deprecated. (6.0) use the built in comparator, or wrap this class in another object that implements these methods
String	toString()
String	toString(ConstantPool cp)	Gets the mnemonic for instruction with symbolic references resolved.

Methods inherited from interface StackConsumer

consumeStack

Modifier and Type	Method	Description
int	consumeStack(ConstantPoolGen cpg)	Gets how many words are consumed from stack.

Constructor Details

IF_ICMPGT

public IF_ICMPGT(InstructionHandle target)

Constructs an IF_ICMPGT instruction.

Parameters:

target - The target instruction.

Method Details

accept

public void accept(Visitor v)

Call corresponding visitor method(s). The order is: Call visitor methods of implemented interfaces first, then call methods according to the class hierarchy in descending order, that is, the most specific visitXXX() call comes last.

Specified by:

accept in class Instruction

Parameters:

v - Visitor object.

negate

public IfInstruction negate()

Description copied from class: IfInstruction

Gets the negation of this instruction.

Specified by:

negate in class IfInstruction

Returns:

negation of instruction.
