Interface Interpolator

    • Method Detail

      • addValueSource

        void addValueSource​(ValueSource valueSource)
        Add a new ValueSource to the stack used to resolve expressions in this interpolator instance.
        Parameters:
        valueSource - ValueSource.
      • removeValuesSource

        void removeValuesSource​(ValueSource valueSource)
        Remove the specified ValueSource from the stack used to resolve expressions in this interpolator instance.
        Parameters:
        valueSource - ValueSource.
      • interpolate

        java.lang.String interpolate​(java.lang.String input,
                                     java.lang.String thisPrefixPattern,
                                     RecursionInterceptor recursionInterceptor)
                              throws InterpolationException
        Attempt to resolve all expressions in the given input string, using the given pattern to first trim an optional prefix from each expression. The supplied recursion interceptor will provide protection from expression cycles, ensuring that the input can be resolved or an exception is thrown. return an empty String if input is null
        Parameters:
        input - The input string to interpolate
        thisPrefixPattern - An optional pattern that should be trimmed from the start of any expressions found in the input.
        recursionInterceptor - Used to protect the interpolation process from expression cycles, and throw an exception if one is detected.
        Returns:
        interpolated string.
        Throws:
        InterpolationException - in case of an error.
      • getFeedback

        java.util.List getFeedback()
        Return any feedback messages and errors that were generated - but suppressed - during the interpolation process. Since unresolvable expressions will be left in the source string as-is, this feedback is optional, and will only be useful for debugging interpolation problems.
        Returns:
        a List that may be interspersed with String and Throwable instances.
      • clearFeedback

        void clearFeedback()
        Clear the feedback messages from previous interpolate(..) calls.
      • isCacheAnswers

        boolean isCacheAnswers()
        Returns:
        state of the cacheAnswers
      • setCacheAnswers

        void setCacheAnswers​(boolean cacheAnswers)
        Parameters:
        cacheAnswers - true/false.
      • clearAnswers

        void clearAnswers()
