Constructor Details

IINC

public IINC(int n,
 int c)

Constructs an IINC instruction.

Parameters:

n - index of local variable.

c - increment factor.

Method Details

accept

public void accept(Visitor v)

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, 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 byte code to stream out.

Overrides:

dump in class LocalVariableInstruction

Parameters:

out - Output stream.

Throws:

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

getIncrement

public final int getIncrement()

Gets the increment factor.

Returns:

increment factor.

getType

public Type getType(ConstantPoolGen cp)

Gets the int type.

Specified by:

getType in interface TypedInstruction

Overrides:

getType in class LocalVariableInstruction

Parameters:

cp - the constant pool generator.

Returns:

int type.

initFromFile

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

Reads needed data (for example index) from file.

Overrides:

initFromFile in class LocalVariableInstruction

Parameters:

bytes - byte sequence to read from.

wide - "wide" instruction flag.

Throws:

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

setIncrement

public final void setIncrement(int c)

Sets increment factor.

Parameters:

c - the increment factor.

setIndex

public final void setIndex(int n)

Sets index of local variable.

Specified by:

setIndex in interface IndexedInstruction

Overrides:

setIndex in class LocalVariableInstruction

Parameters:

n - the index.

• LocalVariableInstruction.setIndexOnly(int)

toString

public String toString(boolean verbose)

Returns mnemonic for instruction.

Overrides:

toString in class LocalVariableInstruction

Parameters:

verbose - long/short format switch.

Returns:

mnemonic for instruction.
