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.

When To Use

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

                throws IOException,
                       AutomationException

Opens the workspace specified by the connection properties.

Remarks

Open takes as input a property set of connection properties that specify the workspace to connect to. In the case of file system workspaces and local database workspaces, a single property named DATABASE, whose value is the pathname to the workspace, is usually all that is required. In the case of remote database workspaces accessed via ArcSDE the properties can include the USER, PASSWORD, DATABASE, SERVER, INSTANCE, VERSION, HISTORICAL_NAME, HISTORICAL_TIMESTAMP, and AUTHENTICATION_MODE properties of the database being connected to.

List of acceptable connection property names and a brief description of each

"SERVER" – SDE server name you are connecting to.

"INSTANCE" – Instance you are connection to.

"DATABASE" – Database connected to.

"USER" – Connected user.

"PASSWORD" – Connected password.

"AUTHENTICATION_MODE" – Credential authentication mode of the connection. Acceptable values are "OSA" and "DBMS".

"VERSION" – Transactional version to connect to. Acceptable value is a string that represents a transaction version name.

"HISTORICAL_NAME" – Historical version to connect to. Acceptable value is a string type that represents a historical marker name.

"HISTORICAL_TIMESTAMP" – Moment in history to establish an historical version connection. Acceptable value is a date time that represents a moment timestamp.

Notes:

• The "DATABASE" property is optional and is required for ArcSDE instances that manage multiple databases (for example, SQL Server).
• If “AUTHENTICATION_MODE” is “OSA” then “USER” and “PASSWORD” are not required. “OSA” represents operating system authentication and uses the operating system credentials to establish a connection with the database.
• Since the workspace connection can only represent one version only 1 of the 3 version properties (“VERSION” or “HISTORICAL_NAME” or “HISTORICAL_TIMESTAMP”) should be used.

Supported Platforms

Windows, Solaris, Linux

Specified by:

open in interface IWorkspaceFactory

Parameters:

connectionProperties - A reference to a com.esri.arcgis.system.IPropertySet (in)

hWnd - The hWnd (A COM typedef) (in)

Returns:

A reference to a com.esri.arcgis.geodatabase.IWorkspace

Throws:

IOException - If there are interop problems.

AutomationException - If the ArcObject component throws an exception.

openFromFile

public IWorkspace openFromFile(String fileName,
                               int hWnd)
                        throws IOException,
                               AutomationException

Opens the workspace specified by the given file name.

Remarks

OpenFromFile takes the pathname of a file or directory that represents either a FileSystemWorkspace or LocalDatabaseWorkspace, or a connection file to a RemoteDatabase workspace and returns an interface on the specified workspace. Clients of these methods can then proceed to open and access datasets in the workspace. If these methods are called with insufficient properties, then the user will be presented with a connection dialog that will prompt for the required properties.

The hWnd argument is the parent window or application's window. The hWnd will guarantee that the connection dialog, if presented to you because of insufficient properties, has the correct parent.

Supported Platforms

Windows, Solaris, Linux

Specified by:

openFromFile in interface IWorkspaceFactory

Parameters:

fileName - The fileName (in)

hWnd - The hWnd (A COM typedef) (in)

Returns:

A reference to a com.esri.arcgis.geodatabase.IWorkspace

Throws:

IOException - If there are interop problems.

AutomationException - If the ArcObject component throws an exception.

create

public IWorkspaceName create(String parentDirectory,
                             String name,
                             IPropertySet connectionProperties,
                             int hWnd)
                      throws IOException,
                             AutomationException

Creates a new workspace specified by the directory, file name, and connection properties.

Remarks

Create has different results depending on the type of workspace factory. If you are working with ArcSDE, a new connection file (.sde) is created. If you are working with an ArcGIS for Desktop Advanced workspace factory, a folder with an INFO subfolder is created. The optional ConnectionProperties parameter specifies any additional connection properties needed, such as the server, instance, user and password in the case where a connection file to a remote database workspace is being created. If no connection properties are specified, this method will result in a dialog being displayed that prompts the user for the required properties.
