    • Constructor Detail

      • ForArgument

        protected ForArgument​(int index)
        Creates a new fixed value implementation that returns a method's argument.
        Parameters:
        index - The argument's index.
      • ForArgument

        private ForArgument​(Assigner assigner,
                            Assigner.Typing typing,
                            int index)
        Creates a new fixed value implementation that returns a method's argument.
        Parameters:
        assigner - The assigner to use for assigning the fixed value to the return type of the instrumented value.
        typing - Indicates if dynamic type castings should be attempted for incompatible assignments.
        index - The argument's index.
    • Method Detail

      • apply

        public ByteCodeAppender.Size apply​(org.objectweb.asm.MethodVisitor methodVisitor,
                                           Implementation.Context implementationContext,
                                           MethodDescription instrumentedMethod)
        Applies this byte code appender to a type creation process.
        Specified by:
        apply in interface ByteCodeAppender
        Parameters:
        methodVisitor - The method visitor to which the byte code appender writes its code to.
        implementationContext - The implementation context of the current type creation process.
        instrumentedMethod - The method that is the target of the instrumentation.
        Returns:
        The required size for the applied byte code to run.
      • appender

        public ByteCodeAppender appender​(Implementation.Target implementationTarget)
        Creates a byte code appender that determines the implementation of the instrumented type's methods.
        Specified by:
        appender in interface Implementation
        Parameters:
        implementationTarget - The target of the current implementation.
        Returns:
        A byte code appender for implementing methods delegated to this implementation. This byte code appender is also responsible for handling methods that were added by this implementation on the call to InstrumentedType.Prepareable.prepare(InstrumentedType).
      • withAssigner

        public Implementation withAssigner​(Assigner assigner,
                                           Assigner.Typing typing)
        Defines an explicit assigner to this fixed value implementation.
        Specified by:
        withAssigner in interface FixedValue.AssignerConfigurable
        Parameters:
        assigner - The assigner to use for assigning the fixed value to the return type of the instrumented value.
        typing - Indicates if dynamic type castings should be attempted for incompatible assignments.
        Returns:
        A fixed value implementation that makes use of the given assigner.
