This class provides an opaque data structure which represents a point-in-time
snapshot for an in-memory directory server instance. Note that this snapshot
will reflect only data held in the server (including both user data and any
changelog information, if that is enabled), but will not alter the settings
of the server which are defined through configuration.
Retrieves an unmodifiable map of all entries defined in the server at the
time the snapshot was created. This will include user-defined entries as
sell as changelog entries, but it will exclude the root DSE and the schema
subentry (since they are dynamically generated from the configuration).
