        Creates a new member substitution that requires a specification for how to perform a substitution.
        Parameters:
        methodGraphCompiler - The method graph compiler to use.
        typePoolResolver - The type pool resolver to use.
        strict - true if the method processing should be strict where an exception is raised if a member cannot be found.
        substitution - The substitution to apply.
    • Method Detail

      • stub

        public MemberSubstitution stub()
        Subs any interaction with a matched byte code element. Any value read from the element will be replaced with the stubbed value's default, i.e. null for reference types and the specific 0 value for primitive types. Any written value will simply be discarded.
        Returns:
        A member substitution that stubs any interaction with a matched byte code element.
      • replaceWith

        public MemberSubstitution replaceWith​(java.lang.reflect.Field field)

        Replaces any interaction with a matched byte code element by an interaction with the specified field. If a field is replacing a method or constructor invocation, it is treated as if it was a field getter or setter respectively.

        A replacement can only be applied if the field is compatible to the original byte code element, i.e. consumes an instance of the declaring type if it is not static as an argument and consumes or produces an instance of the field's type.

        Parameters:
        field - The field to access instead of interacting with any of the matched byte code elements.
        Returns:
        A member substitution that replaces any matched byte code element with an access of the specified field.
      • replaceWith

        public MemberSubstitution replaceWith​(FieldDescription fieldDescription)

        Replaces any interaction with a matched byte code element by an interaction with the specified field. If a field is replacing a method or constructor invocation, it is treated as if it was a field getter or setter respectively.

        A replacement can only be applied if the field is compatible to the original byte code element, i.e. consumes an instance of the declaring type if it is not static as an argument and consumes or produces an instance of the field's type.

        Parameters:
        fieldDescription - The field to access instead of interacting with any of the matched byte code elements.
        Returns:
        A member substitution that replaces any matched byte code element with an access of the specified field.
      • doReplaceWith

        protected abstract MemberSubstitution.Substitution doReplaceWith​(FieldDescription fieldDescription)
        Creates a substitution for replacing the byte code elements matched by this instance with an access of the specified field.
        Parameters:
        fieldDescription - The field to access.
        Returns:
        A suitable substitution.
      • replaceWith

        public MemberSubstitution replaceWith​(java.lang.reflect.Method method)

        Replaces any interaction with a matched byte code element by an invocation of the specified method. If a method is replacing a field access, it is treated as if it was replacing an invocation of the field's getter or setter respectively.

        A replacement can only be applied if the method is compatible to the original byte code element, i.e. consumes compatible arguments and returns a compatible value. If the method is not static, it is treated as if this was an implicit first argument.

        Parameters:
        method - The method to invoke instead of interacting with any of the matched byte code elements.
        Returns:
        A member substitution that replaces any matched byte code element with an invocation of the specified method.
      • replaceWith

        public MemberSubstitution replaceWith​(MethodDescription methodDescription)

        Replaces any interaction with a matched byte code element by an invocation of the specified method. If a method is replacing a field access, it is treated as if it was replacing an invocation of the field's getter or setter respectively.

        A replacement can only be applied if the method is compatible to the original byte code element, i.e. consumes compatible arguments and returns a compatible value. If the method is not static, it is treated as if this was an implicit first argument.

        Important: It is not allowed to specify a constructor or the static type initializer as a replacement.

        Parameters:
        methodDescription - The method to invoke instead of interacting with any of the matched byte code elements.
        Returns:
        A member substitution that replaces any matched byte code element with an invocation of the specified method.
      • doReplaceWith

        protected abstract MemberSubstitution.Substitution doReplaceWith​(MethodDescription methodDescription)
        Creates a substitution for replacing the byte code elements matched by this instance with an invocation of the specified method.
        Parameters:
        methodDescription - The method to invoke.
        Returns:
        A suitable substitution.
