Method Detail

renderJsonObject

public static void renderJsonObject(StringBuilder builder,
                                    Map jsonObjectMap,
                                    int padSpaces,
                                    boolean layoutSameLine,
                                    String[] attributeOrderArrray)

Adds a string representation of a JSON object to a string builder. This only supports JSON object which have attribute values that are strings.

Parameters:

builder - the String Builder that has the string value appended to.

jsonObjectMap - a Map that holds the JSON object.

padSpaces - an integer representing the left padding associated with used if not on the same line

layoutSameLine - boolean if true the JSON string will appear on the same line.

attributeOrderArrray - String[] contains a array of Attribute names in the order to appear in the JSON

renderJsonArray

public static void renderJsonArray(StringBuilder builder,
                                   List listJsonArray,
                                   int padSpaces,
                                   boolean itemSameLine,
                                   String[] itemAttributeOrderArrray)

Adds a string representation of a JSON Array to a string builder. This assumes Each array item contains an JSON Object.

Parameters:

builder - the String Builder that has the string value appended to.

listJsonArray - List containing the data to be converted to a JSON Array.

padSpaces - an integer representing the left padding associated with used if not on the same line.

itemSameLine - boolean if set to true will render each item on the same line

itemAttributeOrderArrray - String[] contains a list of String Attribute names in the order to appear in the JSON Object Items

renderAttribute

public static void renderAttribute(StringBuilder builder,
                                   String attName,
                                   Object jsonObj,
                                   int padSpaces,
                                   boolean isFirst,
                                   boolean layoutValueSameLine,
                                   String[] subFieldOrder)

Renders a string representation of a JSON Attribute name and value

Parameters:

builder - the String Builder that has the string value appended to.

attName - this the JSON attribute name

jsonObj - this is the attribute value

padSpaces - this is the attribute spacing

isFirst - boolean if set treats this a the first element. It constructs the first "{" or "["

layoutValueSameLine - boolean this is passed to either the renderJsonArray or renderJsonObject.

subFieldOrder - String[] JSON objects attributes will be sorted in this name order, if null then attributes will be ordered by name alphabetically.

convertMap2JSONList

public static List<Map<String,String>> convertMap2JSONList(Map<String,String> map2Convert,
                                                                 String keyName,
                                                                 String valueName)

Converts a map that holds pair value such as the routeMap to a List<map<String,String>> which can be used to generate a JSON Array.

Parameters:

map2Convert - Map<String,Stringg> that holds the pair value.

keyName - the JSON attribute String name for the key

valueName - The JSON attribute String name for the value

Returns:

List<map<String,String>> the converted List that can be passed to renderJsonArray
