TableSet<E extends Persistable<UUID> > class
A collection of Persistable objects that leverages the sqlite3
library
in which each record can occur only once.
The Database
has two modes, persistent and in-memory.
A persistent Database
is a shared database that will store all its
records on the same Database
file.
An in-memory Database
works on its own independent Database
but it
won't persist multiple library runs.
Access, store or remove Persistable objects as if this were any given Set, all common Set rules apply.
List of limitations in the generics implementation of the Dart type system that complicate this implementation:
