Methods inherited from class ConversionInstruction

getType

Modifier and Type	Method	Description
Type	getType(ConstantPoolGen cp)	Gets the type associated with the instruction.

Methods inherited from class Instruction

consumeStack, copy, dump, equals, getComparator, getLength, getName, getOpcode, hashCode, initFromFile, isValidByte, isValidShort, produceStack, readInstruction, setComparator, toString, 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).
void	dump(DataOutputStream out)	Dumps instruction as byte code to stream out.
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.
protected void	initFromFile(ByteSequence bytes, boolean wide)	Reads needed data (for example index) from file.
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(boolean verbose)	Long output format: <name of opcode> "["<opcode number>"]" "("<length of instruction>")"
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.

Methods inherited from interface StackProducer

produceStack

Modifier and Type	Method	Description
int	produceStack(ConstantPoolGen cpg)	Gets how many words are produced on stack.

Constructor Details

I2S

public I2S()

Constructs an I2S 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.
