• function: validate(inputObject, mapObject)
  • inputObject: input object
  • mapObject: object containing validation rules

object_mapper_validator.js

Key exchange and valiation of object in javascript

Features

• Exchange the keyname with new keyname as specified (in the map object)
• Can apply constraints like
  • the key-value pair is mandatory or not
  • value type (validValueType)
• sub-object keys can also get keyname exchanged
• there can be array of sub-objects that can have keyname exchange
  • Caveat : array that has to get keyname exchanged should be of same object
  • array bound can be set
    • maxLenArray : max length
    • minLenArray : min length
    • not specifying maxLenArray will have no upper bound
  • can enforce only array of object(s) in resultant object (using isObjectArray)
• List of errors occured while validating and keyname exachage

Map Structure

{
    "inputKeyName": {
        "mandatory": "1"
        , "newKeyName": "newKeyName1"
        , "valueValidity": {
            "validValueType": ["string","stringNumber"]
        }
    }
    , "keyName2": {
        "mandatory": "0"
        , "subObject": {
            "ObjectRef": subObjectName2
            , "isObjectArray": 1
            , "minLenArray" : 1
            , "maxLenArray" : 3
        }
    }
}

inputKeyName : The key name in the input object

mandatory : It enforces that the key presense in input object
values :

• 0 - not mandatory
• 1 - mandatory

newKeyName : The key name that has to be in resultant object in place of input key name, if not present the inputkeyName will be retained

valueValidity : object for value validity

validValueType : array of value type that a value for the given key be of (if key validValueType not present there will be no type validation)

• values :
  • any valid javascript object type
  • stringNumber is a special value type which specifies that the value of number but of string type

subObject : subObject properties and constraints are specified here ObjectRef : Sub object name that has to be used

isObjectArray : condition on the object being array or not (if key not present condition is false)

• values :
  • 1 for true
  • 0 for false

minLenArray : Lower bound of number of array objects of subObjectName

• values : any natural number

maxLenArray : Upper bound of number of array objects of subObjectName

• values : any natural number
