Dump instruction as byte code to stream out.

Set increment factor.
void
setIndex (int n)
Set index of local variable.

IINC
public IINC (int n,
int c)
dump
public void dump (java.io.DataOutputStream out)
throws java.io.IOException
Dump instruction as byte code to stream out.
Overrides: dump
in class LocalVariableInstruction
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 LocalVariableInstruction
Following copied from class: org.apache.bcel.generic.Instruction
Parameters: bytes
- byte sequence to read fromwide
- "wide" instruction flag
toString
public java.lang.String toString (boolean verbose)
Description copied from class: LocalVariableInstruction
Long output format:
<name of opcode> "["<opcode number>"]"
"("<length of instruction>")" "<"< local variable index>">"
Overrides: toString
in class LocalVariableInstruction
Returns: mnemonic for instruction
setIndex
public final void setIndex (int n)
Set index of local variable.
Overrides: setIndex
in class LocalVariableInstruction
getIncrement
public final int getIncrement ()
Returns: increment factor
setIncrement
public final void setIncrement (int c)
Set increment factor.
getType
public Type getType (ConstantPoolGen cp)
Description copied from class: LocalVariableInstruction
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 .
Overrides: getType
in class LocalVariableInstruction
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
