Method Summary

Modifier and Type	Method	Description

Methods inherited from class LocalVariableInstruction

dump, getCanonicalTag, getIndex, getType, initFromFile, setIndex, toString

Modifier and Type	Method	Description
void	dump(DataOutputStream out)	Dumps instruction as byte code to stream out.
short	getCanonicalTag()	Gets the canonical tag for instruction, for example, ALOAD for ALOAD_0.
final int	getIndex()	Gets the local variable index (n) referred to by this instruction.
Type	getType(ConstantPoolGen cp)	Gets the type associated with the instruction - in case of ALOAD or ASTORE Type.OBJECT is returned.
protected void	initFromFile(ByteSequence bytes, boolean wide)	Reads needed data (for example index) from file.
void	setIndex(int index)	Sets the local variable index. also updates opcode and length TODO Why?
String	toString(boolean verbose)	Long output format: <name of opcode> "["<opcode number>"]" "("<length of instruction>")" "<"< local variable index>">"

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 class Object

clone, finalize, getClass, notify, notifyAll, wait, wait, wait

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

ASTORE

public ASTORE(int n)

Store reference into local variable

Parameters:

n - index of local variable.

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.

Overrides:

accept in class StoreInstruction

Parameters:

v - Visitor object.
