Constructor Details

IINC

(package private)  IINC()
Empty constructor needed for the Class.newInstance() statement in Instruction.readInstruction(). Not to be used otherwise.

IINC

public IINC(int n,
            int c)
Parameters:
n - index of local variable
c - increment factor

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, i.e., the most specific visitXXX() call comes last.
Overrides:
accept in interface Instruction
Parameters:
v - Visitor object

dump

public void dump(DataOutputStream out)
            throws IOException
Dump instruction as byte code to stream out.
Overrides:
dump in interface LocalVariableInstruction
Parameters:
out - Output stream

getIncrement

public final int getIncrement()
Returns:
increment factor

getType

public Type getType(ConstantPoolGen cp)
Specified by:
getType in interface TypedInstruction
Overrides:
getType in interface LocalVariableInstruction
Returns:
int type

initFromFile

protected void initFromFile(ByteSequence bytes,
                            boolean wide)
            throws IOException
Read needed data (e.g. index) from file.
Overrides:
initFromFile in interface LocalVariableInstruction

setIncrement

public final void setIncrement(int c)
Set increment factor.

setIndex

public final void setIndex(int n)
Set index of local variable.
Specified by:
setIndex in interface IndexedInstruction
Overrides:
setIndex in interface LocalVariableInstruction

setWide

private final void setWide()

toString

public String toString(boolean verbose)
Overrides:
toString in interface LocalVariableInstruction
Returns:
mnemonic for instruction
