Constructor Detail

IINC

public IINC(int n,
            int c)
Method Detail

dump

public void dump(java.io.DataOutputStream out)
          throws java.io.IOException
Dump instruction as byte code to stream out.
Overrides:
dump in class Instruction
Parameters:
out - Output stream

initFromFile

protected void initFromFile(ByteSequence bytes,
                            boolean wide)
                     throws java.io.IOException
Read needed data (e.g. index) from file.
Overrides:
initFromFile in class Instruction
Following copied from class: de.fub.bytecode.generic.Instruction
Parameters:
bytes - byte sequence to read from
wide - "wide" instruction flag

toString

public java.lang.String toString(boolean verbose)
Description copied from class: Instruction
Long output format: <name of opcode> "["<opcode number>"]" "("<length of instruction>")"
Overrides:
toString in class Instruction
Returns:
mnemonic for instruction

getIndex

public final int getIndex()
Specified by:
getIndex in interface IndexedInstruction
Returns:
index of local variable referred by this instruction.

setIndex

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

getIncrement

public final int getIncrement()
Returns:
increment factor

setIncrement

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

getType

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

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 class Instruction
Parameters:
v - Visitor object
