Data Management
transaction that has locked an object, or start a new transaction.
ITransactionManager is defined as:
public interface ITransactionManager
{
object DefaultTransactionContext { get; }
ITransaction NewTransaction (object context);
ITransaction GetCurrent (object context);
ITransaction GetTransaction (object data);
}
event EventHandler TransactionStarted;
event EventHandler TransactionCompleted;
So to find the current transaction in the default context (usually the current thread) you
would use:
//Get the current context
object defaultContext =
DataManager.TransactionManager.DefaultTransactionContext;
//Find the current transaction
ITransaction trans =
DataManager.TransactionManager.GetCurrent(defaultContext);
Workspace Property
The Workspace property represents the in-memory state of the system known as the
workspace. However, in Ocean Petrel it represents a sub-store attached to the current
primary project. The user may add objects to the workspace to track their state in the
users’ session. It is up to the application to store any workspace state information if it is to
be used in later sessions. An example of this would be storing the type and content of
windows open when the session ends so they can be displayed at the start of the next
session. Only one workspace is active at a time. The Workspace property guarantees the
presence of IDataSource so objects can rely on having a data source available for
object persistence.
