Class IINC

    • Field Detail

      • wide

        private boolean wide

      • c

        private int c

    • Constructor Detail

      • IINC

        IINC()
        Empty constructor needed for Instruction.readInstruction. Not to be used otherwise.

      • IINC

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

    • Method Detail

      • 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, i.e., the most specific visitXXX() call comes last.
        Specified by:
        accept in class Instruction
        Parameters:
        v - Visitor object

      • dump

        public void dump​(java.io.DataOutputStream out)
          throws java.io.IOException
        Dumps instruction as byte code to stream out.
        Overrides:
        dump in class LocalVariableInstruction
        Parameters:
        out - Output stream
        Throws:
        java.io.IOException - Thrown when an I/O exception of some sort has occurred.

      • getIncrement

        public final int getIncrement()
        Returns:
        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 .
        Specified by:
        getType in interface TypedInstruction
        Overrides:
        getType in class LocalVariableInstruction
        Returns:
        int type

      • initFromFile

        protected void initFromFile​(ByteSequence bytes,
                            boolean wide)
                     throws java.io.IOException
        Reads needed data (e.g. index) from file.
        Overrides:
        initFromFile in class LocalVariableInstruction
        Parameters:
        bytes - byte sequence to read from
        wide - "wide" instruction flag
        Throws:
        java.io.IOException - may be thrown if the implementation needs to read data from the file

      • setIncrement

        public final void setIncrement​(int c)
        Sets increment factor.

      • setWide

        private void setWide()

      • toString

        public java.lang.String toString​(boolean verbose)
        Returns mnemonic for instruction.
        Overrides:
        toString in class LocalVariableInstruction
        Parameters:
        verbose - long/short format switch
        Returns:
        mnemonic for instruction.
