Class NameSignatureInstruction

java.lang.Object

org.apache.bcel.generic.Instruction

org.apache.bcel.generic.CPInstruction

org.apache.bcel.generic.NameSignatureInstruction

All Implemented Interfaces:

Cloneable, IndexedInstruction, TypedInstruction

public abstract class NameSignatureInstruction
extends CPInstruction

Superclass for FieldOrMethod and INVOKEDYNAMIC, since they both have names and signatures

Since:

6.0

Constructor Summary

Constructors

Constructor	Description
NameSignatureInstruction()	Constructs a NameSignatureInstruction.

Method Summary

Modifier and Type	Method	Description
String	getName(ConstantPoolGen cpg)	Gets the name of the referenced method or field.
ConstantNameAndType	getNameAndType(ConstantPoolGen cpg)	Gets the name and type constant.
String	getSignature(ConstantPoolGen cpg)	Gets the signature of the referenced method or field.

Methods inherited from class CPInstruction

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

Modifier and Type	Method	Description
void	dump(DataOutputStream out)	Dumps instruction as byte code to stream out.
final int	getIndex()	Gets the constant pool index referred to by this instruction.
Type	getType(ConstantPoolGen cpg)	Gets the type associated with this instruction.
protected void	initFromFile(ByteSequence bytes, boolean wide)	Reads needed data (that is, index) from file.
void	setIndex(int index)	Sets the index to constant pool.
String	toString(boolean verbose)	Long output format: <name of opcode> "["<opcode number>"]" "("<length of instruction>")" "<"< constant pool index>">"
String	toString(ConstantPool cp)	Gets the mnemonic for instruction with symbolic references resolved.

Methods inherited from class Instruction

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

Modifier and Type	Method	Description
abstract void	accept(Visitor v)	Call corresponding visitor method(s).
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()
