Constructors

PushIdGenerator()

String const PUSH_CHARS

The 64 characters used in generated keys, in sort order.

String generatePushChildName()

Generates a unique 20-character key.

The first 8 characters encode the current time, so keys sort by creation time. Used by CollectionReference.document when no name is given.
