Type Parameters

• KeyType
  The key type must correspond to the .Net type of the record keys.

Parameters

• json
  Type: System.String

  A string formatted in JavaScript Object Notation (JSON), holding JavaScript representations of Change objects.

• embeddedDataTypes
  Type: System.Collections.Generic.IEnumerable<Type>

  A list of .Net types that may be encountered during deserialization.

• builder
  Type: Microsoft.SharePoint.JSGrid.ObjectBuilderFromSerialized

  Used when encountering serialized data in the JSON stream, a delegate to create an object of the appropriate C# type, given a localized string. For instance, this delegate might take the string “4” and return a Int32 with the value 4.

• propTypeGenerator
  Type: Microsoft.SharePoint.JSGrid.CellPropTypeIdRetriever

  Used to determine the property type ID of any encountered property updates. This is a delegate that takes a string representing of a serialized record key and a string representing the field key, and returns a property type ID.

Return Value

Type: System.Collections.Generic.IList<Change>
