Constructors

Constructor	Description
SIPUSH(short b)	Constructs a SIPUSH.

Method Summary

Modifier and Type	Method	Description
void	accept(Visitor v)	Call corresponding visitor method(s).
void	dump(DataOutputStream out)	Dumps instruction as short code to stream out.
Type	getType(ConstantPoolGen cp)	Gets Type.SHORT.
Number	getValue()	Gets the value to push onto the stack.
protected void	initFromFile(ByteSequence bytes, boolean wide)	Reads needed data (for example index) from file.
String	toString(boolean verbose)	Long output format: <name of opcode> "["<opcode number>"]" "("<length of instruction>")"

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 StackProducer

produceStack

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

Constructor Details

SIPUSH

public SIPUSH(short b)

Constructs a SIPUSH.

Parameters:

b - The value.

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.

dump

public void dump(DataOutputStream out)
          throws IOException

Dumps instruction as short code to stream out.

Overrides:

dump in class Instruction

Parameters:

out - Output stream.

Throws:

IOException - Thrown when an I/O exception of some sort has occurred.

getType

public Type getType(ConstantPoolGen cp)

Gets Type.SHORT.

Specified by:

getType in interface TypedInstruction

Parameters:

cp - The constant pool generator.

Returns:

Type.SHORT.

getValue

public Number getValue()

Description copied from interface: ConstantPushInstruction

Gets the value to push onto the stack.

Specified by:

getValue in interface ConstantPushInstruction

Returns:

The value to push onto the stack.

initFromFile

protected void initFromFile(ByteSequence bytes,
 boolean wide)
                     throws IOException

Reads needed data (for example index) from file.

Overrides:

initFromFile in class Instruction

Parameters:

bytes - byte sequence to read from.

wide - "wide" instruction flag.

Throws:

IOException - Thrown if the implementation needs to read data from the file

toString

public String toString(boolean verbose)

Description copied from class: Instruction

Long output format: <name of opcode> "["<opcode number>"]" "("<length of instruction>")"

Overrides:

toString in class Instruction

Parameters:

verbose - long/short format switch.

Returns:

mnemonic for instruction.
