Method Summary

Modifier and TypeMethod and Description
public void

Constructor Detail

IINCback to summary
pack-priv IINC()

Empty constructor needed for Instruction.readInstruction. Not to be used otherwise.

IINCback to summary
public IINC(final int n, final int c)
Parameters
n:int

index of local variable

c:int

increment factor

Method Detail

acceptback to summary
public void accept(final Visitor v)

Implements abstract org.apache.bcel.generic.Instruction.accept.

Calls 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, i.e., the most specific visitXXX() call comes last.

Parameters
v:Visitor

Visitor object

Annotations
@Override
dumpback to summary
public void dump(final DataOutputStream out) throws IOException

Overrides org.apache.bcel.generic.LocalVariableInstruction.dump.

Dumps instruction as byte code to stream out.

Parameters
out:DataOutputStream

Output stream

Annotations
@Override
Exceptions
IOException:

Doc from org.apache.bcel.generic.Instruction.dump.

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

getIncrementback to summary
public final int getIncrement()
Returns:int

increment factor

getTypeback to summary
public Type getType(final ConstantPoolGen cp)

Overrides org.apache.bcel.generic.LocalVariableInstruction.getType.

Implements org.apache.bcel.generic.TypedInstruction.getType.

Doc from org.apache.bcel.generic.LocalVariableInstruction.getType.

Returns the type associated with the instruction - in case of ALOAD or ASTORE Type.OBJECT is returned. This is just a bit incorrect, because ALOAD and ASTORE may work on every ReferenceType (including Type.NULL) and ASTORE may even work on a ReturnaddressType .

Returns:Type

int type

Annotations
@Override
initFromFileback to summary
protected void initFromFile(final ByteSequence bytes, final boolean wide) throws IOException

Overrides org.apache.bcel.generic.LocalVariableInstruction.initFromFile.

Parameters
bytes:ByteSequence

Doc from org.apache.bcel.generic.Instruction.initFromFile.

byte sequence to read from

wide:boolean

Doc from org.apache.bcel.generic.Instruction.initFromFile.

"wide" instruction flag

may be thrown if the implementation needs to read data from the file

setIncrementback to summary
public final void setIncrement(final int c)

Sets increment factor.

setIndexback to summary
public final void setIndex(final int n)

Overrides org.apache.bcel.generic.LocalVariableInstruction.setIndex.

Implements org.apache.bcel.generic.IndexedInstruction.setIndex.

Sets index of local variable.

long/short format switch

Returns:String

mnemonic for instruction.
