Class SpecStringParser

java.lang.Object

com.bazaarvoice.jolt.common.SpecStringParser

public class SpecStringParser
extends Object

Static utility methods for handling specStrings such that we can process them into usable formats for further processing into PathElement objects

Method Summary

Modifier and Type	Method and Description
static String	fixLeadingBracketSugar(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 String	parseAtPathElement(Iterator<Character> iter, String dotNotationRef) Parse RHS Transpose @ logic.
static List<String>	parseDotNotation(List<String> pathStrings, Iterator<Character> iter, String dotNotationRef) Method that recursively parses a dotNotation String based on an iterator.
static List<String>	parseFunctionArgs(String argString)
static String	removeEscapeChars(String origKey)
static String	removeEscapedValues(String origKey)
static Iterator<Character>	stringIterator(String string) Helper method to turn a String into an Iterator

Method Detail

parseDotNotation

public static List<String> parseDotNotation(List<String> pathStrings,
                                            Iterator<Character> iter,
                                            String dotNotationRef)

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 Iterator<Character> stringIterator(String string)

Helper method to turn a String into an Iterator

fixLeadingBracketSugar

public static String fixLeadingBracketSugar(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 String parseAtPathElement(Iterator<Character> iter,
                                        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

removeEscapedValues

public static String removeEscapedValues(String origKey)

removeEscapeChars

public static String removeEscapeChars(String origKey)

parseFunctionArgs

public static List<String> parseFunctionArgs(String argString)
