class EL_SOLITARY
Client examples: ADDRESS_TABLE ; CUSTOMER_TABLE ; DATABASE ; ISE_CLASS_TABLE ; RBOX_DATABASE ; SLIDE_SHOW
Object is a solitary globally shared instance, i.e. a singleton
Use one of the following classes in a once routine to retrieve this object from Singleton_table
For example:
feature {NONE} -- Constants
Database: RBOX_DATABASE
once
Result := create {EL_CONFORMING_SINGLETON [RBOX_DATABASE]}
end
In this example the routine will return either RBOX_DATABASE or RBOX_TEST_DATABASE depending on which instance is found in Singleton_table.
