Method Summary

Modifier and TypeMethod and Description
public void
accept(final Visitor
Visitor object
v)

Implements abstract com.sun.org.apache.bcel.internal.generic.Instruction.accept.

Calls corresponding visitor method(s).

public void
dump(final DataOutputStream
Output stream
out)

Overrides com.sun.org.apache.bcel.internal.generic.LocalVariableInstruction.dump.

Dumps instruction as byte code to stream out.

public final int
getIncrement()

Returns: increment factor

public Type

Returns:

int type
getType(final ConstantPoolGen cp)

Overrides com.sun.org.apache.bcel.internal.generic.LocalVariableInstruction.getType.

Implements com.sun.org.apache.bcel.internal.generic.TypedInstruction.getType.

Returns the type associated with the instruction - in case of ALOAD or ASTORE Type.OBJECT is returned.

protected void
initFromFile(final ByteSequence bytes, final boolean wide)

Overrides com.sun.org.apache.bcel.internal.generic.LocalVariableInstruction.initFromFile.

Reads needed data (e.g. index) from file.

public final void
setIncrement(final int c)

Sets increment factor.

public final void
setIndex(final int n)

Overrides com.sun.org.apache.bcel.internal.generic.LocalVariableInstruction.setIndex.

Implements com.sun.org.apache.bcel.internal.generic.IndexedInstruction.setIndex.

Sets index of local variable.

private void
setWide()

public String

Returns:

mnemonic for instruction.
toString(final boolean verbose)

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 com.sun.org.apache.bcel.internal.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

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

Overrides com.sun.org.apache.bcel.internal.generic.LocalVariableInstruction.dump.

Dumps instruction as byte code to stream out.

Parameters
out:DataOutputStream

Output stream

Annotations
@Override
Exceptions
IOException:

Doc from com.sun.org.apache.bcel.internal.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 com.sun.org.apache.bcel.internal.generic.LocalVariableInstruction.getType.

Implements com.sun.org.apache.bcel.internal.generic.TypedInstruction.getType.

Doc from com.sun.org.apache.bcel.internal.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

Annotations
@Override
Exceptions
IOException:

Doc from com.sun.org.apache.bcel.internal.generic.Instruction.initFromFile.

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