Some information relates to prerelease product that may be substantially modified before it’s released. Microsoft makes no warranties, express or implied, with respect to the information provided here.
A data source that can parse a JSON text stream and notify any data consumers listening for changes.
This data source has on Unity specific dependencies.
TODO: refactor this to use DataSourceObjects. Should be a fairly straight refactor since DataSourceObjects was derived from this source code. See DataNodeJson
TODO: Add support for SetValue() and ability to report changes to a back-end services for persisting those changes. This would then allow for data entry slates.
