Operations on McDBLib/McODBE/POET objects are done in a transactable (tentative pending resolution) manner. This functionality is achieved by performing object operations within a transaction context (McDBTransaction). The McDBTransactions collection represents all transactions that McDBLib is aware of (has issued).
The McDBTransactions collection encapsulates all transactions managed by the database engine, only one of which may be active at a time (i.e. encapsulating the valid, existing object(s)). This property will read or set this value.
