Examples of org.datanucleus.store.mapped.IdentifierFactory.newIdentifier()

org.datanucleus.store.mapped.IdentifierFactory.newIdentifier()
To be called when we want an identifier name creating based on the identifier. Creates identifier for COLUMN, FOREIGN KEY, INDEX and TABLE @param identifierType the type of identifier to be created @param identifierName The identifier name @return The DatastoreIdentifier

             * So even though the caller may have been looking for column FOO
             * relative to rangevar THIS he may actually get back something like
             * THIS_1.FOO.
