ArcObjects Library Reference (GeoDatabase)

IWorkspaceFactory Interface

Provides access to members that create and open workspaces and supply workspace factory information. Note: the IWorkspaceFactory interface has been superseded byIWorkspaceFactory2. Please consider using the more recent version.

Product Availability

Available with ArcGIS Engine, ArcGIS Desktop, and ArcGIS Server.

When To Use

Use IWorkspaceFactory when you need to create a new workspace, connect to an existing workspace or find information about a workspace.

Remarks

A WorkspaceFactory is a dispenser of workspaces and allows a client to connect to a workspace specified by a set of connection properties. A workspace represents a database or a datasource that contains one or more datasets. Examples of datasets include tables, feature classes and relationship classes. A WorkspaceFactory is a cocreatable, singleton object. Connection properties are specified using a PropertySet object and can be saved to a connection file. A WorkspaceFactory also supports methods that can be used to browse and manage file system workspaces, and methods to manage connection files for remote database workspaces.

Each workspace factory maintains a pool of currently connected, active workspaces that are referenced by the application. When any of the Open* methods is called, the workspace factory first checks to see if a workspace has previously been opened with a matching set of properties. If so, a reference to the existing instance is returned. In the case of ArcSDE workspaces, when an application connects to a workspace but omits some connection properties (such as username, password, or version), the workspace factory will check a set of "core" properties - SERVER, INSTANCE, and AUTHENTICATION_MODE - to see they match any open workspaces. If so, the workspace factory will return a reference to the matching workspace.
