    • Method Detail

      • accept

        public void accept​(Visitor v)

        Parameters:
        v - Visitor object.

      • consumeStack

        public int consumeStack​(ConstantPoolGen cpg)
        Description copied from class: InvokeInstruction
        Also works for instructions whose stack effect depends on the constant pool entry they reference.
        Specified by:
        consumeStack in interface StackConsumer
        Overrides:
        consumeStack in class InvokeInstruction
        Parameters:
        cpg - the constant pool generator.
        Returns:
        Number of words consumed from stack by this instruction.

      • dump

        public void dump​(java.io.DataOutputStream out)
          throws java.io.IOException
        Dumps instruction as byte code to stream out.
        Overrides:

        Parameters:
        out - Output stream.
        Throws:

        Description copied from interface: ExceptionThrower
        Gets the exceptions that may be thrown by this instruction.
        Returns:
        the exceptions that may be thrown by this instruction.

      • initFromFile

        protected void initFromFile​(ByteSequence bytes,
                            boolean wide)
                     throws java.io.IOException

        Parameters:
        bytes - input stream.
        wide - wide prefix?.
        Throws:
        java.io.IOException - may be thrown if the implementation needs to read data from the file

      • toString

        public java.lang.String toString​(ConstantPool cp)
        Description copied from class: Instruction
        Gets the mnemonic for instruction with symbolic references resolved.
        Overrides:
        toString in class InvokeInstruction
        Parameters:
        cp - the constant pool.
        Returns:
