Class SpecStringParser

  • public class SpecStringParser
extends java.lang.Object

      Modifier and Type Method Description
      static java.lang.String fixLeadingBracketSugar​(java.lang.String dotNotaton)
      Given a dotNotation style outputPath like "data[2].&(1,1)", this method fixes the syntactic sugar of "data[2]" --> "data.[2]" This makes all the rest of the String processing easier once we know that we can always split on the '.' character.
      static java.lang.String parseAtPathElement​(java.util.Iterator<java.lang.Character> iter, java.lang.String dotNotationRef)
      Parse RHS Transpose @ logic.
      static java.util.List<java.lang.String> parseDotNotation​(java.util.List<java.lang.String> pathStrings, java.util.Iterator<java.lang.Character> iter, java.lang.String dotNotationRef)
      Method that recursively parses a dotNotation String based on an iterator.
      static java.util.List<java.lang.String> parseFunctionArgs​(java.lang.String argString)  
      static java.lang.String removeEscapeChars​(java.lang.String origKey)  
      static java.lang.String removeEscapedValues​(java.lang.String origKey)  
      static java.util.Iterator<java.lang.Character> stringIterator​(java.lang.String string)
      Helper method to turn a String into an Iterator

        Method that recursively parses a dotNotation String based on an iterator. This method will call out to parseAtPathElement
        Parameters:
        pathStrings - List to store parsed Strings that each represent a PathElement
        iter - the iterator to pull characters from
        dotNotationRef - the original dotNotation string used for error messages
        Returns:
        evaluated List from dot notation string spec

      • stringIterator

        public static java.util.Iterator<java.lang.Character> stringIterator​(java.lang.String string)
        Helper method to turn a String into an Iterator

      • fixLeadingBracketSugar

        public static java.lang.String fixLeadingBracketSugar​(java.lang.String dotNotaton)
        Given a dotNotation style outputPath like "data[2].&(1,1)", this method fixes the syntactic sugar of "data[2]" --> "data.[2]" This makes all the rest of the String processing easier once we know that we can always split on the '.' character.
        Parameters:
        dotNotaton - Output path dot notation
        Returns:

      • parseAtPathElement

        public static java.lang.String parseAtPathElement​(java.util.Iterator<java.lang.Character> iter,
                                                  java.lang.String dotNotationRef)
        Parse RHS Transpose @ logic. "@(a.b)" --> pulls "(a.b)" off the iterator "@a.b" --> pulls just "a" off the iterator This method expects that the the '@' character has already been seen.
        Parameters:
        iter - iterator to pull data from
        dotNotationRef - the original dotNotation string used for error messages
