DatasyncValue

class DatasyncValue : TreeLikeData

Represents a tree-like value stored by the Webcom datasync service within its real-time database.

This class provides methods to easily convert it to native primitive or composite types (Boolean, String, Number, Map, List) or business objects (kotlinx.serialization.Serializable-annotated classes or POJO classes).
