DataSnapshot

actual class DataSnapshot(source)

An immutable copy of the data at a location, as the Android SDK's DataSnapshot. value is the natural type of the data: a Map, a List, a String, a Boolean, a Long, a Double or null. Mapping to custom classes through getValue(Class) is Android-only; the GenericTypeIndicator form casts the value on the other platforms.
