Class INVOKEDYNAMIC

    • Constructor Detail

      • INVOKEDYNAMIC

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

      • INVOKEDYNAMIC

        public INVOKEDYNAMIC​(int index)

    • Method Detail

      • 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, that is, 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 CPInstruction
        Parameters:
        out - Output stream.
        Throws:
        java.io.IOException - Thrown when an I/O exception of some sort has occurred.

      • getClassName

        public java.lang.String getClassName​(ConstantPoolGen cpg)
        Override the parent method because our class name is held elsewhere. Note: Contrary to this method's name it does not return the class name of the invoke target; rather it returns the name of the method that will be used to invoke the Lambda method generated by this invoke dynamic instruction.
        Overrides:
        getClassName in class InvokeInstruction
        Parameters:
        cpg - the constant pool generator.
        Returns:
        name of the referenced class/interface.

      • getExceptions

        public java.lang.Class<?>[] getExceptions()
        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.

      • getReferenceType

        public ReferenceType getReferenceType​(ConstantPoolGen cpg)
        Since InvokeDynamic doesn't refer to a reference type, just return Object, as that is the only type we can say for sure the reference will be.
        Overrides:
        getReferenceType in class FieldOrMethod
        Parameters:
        cpg - the ConstantPoolGen used to create the instruction.
        Returns:
        an ObjectType for Object.
        Since:
        6.1

      • initFromFile

        protected void initFromFile​(ByteSequence bytes,
                            boolean wide)
                     throws java.io.IOException
        Reads needed data (that is, index) from file.
        Overrides:
        initFromFile in class CPInstruction
        Parameters:
        bytes - input stream.
        wide - wide prefix?.
        Throws:
        java.io.IOException - may be thrown if the implementation needs to read data from the file
