public final class Fork
extends View

A fork is a database view, allowing both read and write operations.

A fork represents the database state at the time it was created plus any changes to the database made using this fork.

A fork allows to perform a transaction: a number of independent writes to the database, which then may be atomically applied (i.e. committed) to the database and change the database state.
