Product Availability

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

Supported Platforms

Windows, Solaris, Linux

Specified by:
containsWorkspace in interface IPlugInWorkspaceFactoryHelper
Specified by:
containsWorkspace in interface IWorkspaceFactory
Parameters:
parentDirectory - The parentDirectory (in)
fileNames - A reference to a com.esri.arcgis.system.IFileNames (in)
Returns:
The containsWorkspace
Throws:
IOException - If there are interop problems.
AutomationException - If the ArcObject component throws an exception.

getWorkspaceString

public String getWorkspaceString(String parentDirectory,
                                 IFileNames fileNames)
                          throws IOException,
                                 AutomationException
If parentDirectory is or contains a valid workspace, gets a string uniquely identifying that workspace.

Description

If (1) the fileNames parameter is not null and ContainsWorkspace is true for this parentDirectory and list of fileNames, or (2) fileNames is null and IsWorkspace returns true for this parentDirectory, this method returns a string which represents this workspace and succeeds with S_OK as the HRESULT. Otherwise it returns null and succeeds with S_FALSE as the HRESULT. In the case where the fileNames parameter is not null, you must remove any files from the array that belong to your data source.

Note that for database data sources, parentDirectory will be the database or connection file when fileNames is null.

Remarks

This string can be passed to OpenWorkspace to open the workspace helper class for this workspace. For file- and folder-based data sources, the parentDirectory is considered the workspace. For database data sources, the first database in the list is considered the workspace. Files claimed by this data source (including .xml metadata files) must be removed from fileNames. (Note that database data sources should only remove the first database.) This function will be called repeatedly until it fails.
The content of the workspace strings is determined solely by the plug-in. Workspace strings are obtained from GetWorkspaceString and passed to IsWorkspace and OpenWorkspace. They are used as a lightweight representation of a workspace. For many data sources, the path to the workspace will be a good workspace string, but the strings can be anything. However, workspace strings containing reserved characters such as '=' should be enclosed by parentheses so that parsing will be safe.

Supported Platforms

Windows, Solaris, Linux

Specified by:
getWorkspaceString in interface IPlugInWorkspaceFactoryHelper
Parameters:
parentDirectory - The parentDirectory (in)
fileNames - A reference to a com.esri.arcgis.system.IFileNames (in)
Returns:
The wksString
Throws:
IOException - If there are interop problems.
AutomationException - If the ArcObject component throws an exception.

openWorkspace

public IPlugInWorkspaceHelper openWorkspace(String wksString)
                                     throws IOException,
                                            AutomationException
Opens a workspace helper for the workspace identified by the workspace string.

Description

Creates and initializes an instance of the workspace helper class and returns its IPlugInWorkspaceHelper pointer. The wksString may have been obtained from GetWorkspaceString, or it may be a custom string specified to IWorkspaceFactory::Open. If the wksString is not valid, the method should fail and return a null pointer.

Product Availability

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

Supported Platforms

Windows, Solaris, Linux

Specified by:
openWorkspace in interface IPlugInWorkspaceFactoryHelper
Parameters:
wksString - The wksString (in)
Returns:
A reference to a com.esri.arcgis.geodatabase.IPlugInWorkspaceHelper
Throws:
IOException - If there are interop problems.
AutomationException - If the ArcObject component throws an exception.

open

public IWorkspace open(IPropertySet connectionProperties,
                       int hWnd)
                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.

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.

Product Availability

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

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.

Remarks

GetWorkspaceName is useful when browsing the file system for workspaces. It is handed in a parent directory and the list of file names in the directory to be examined. It returns a WorkspaceName object representing the first workspace it finds in the list of filenames and removes any filenames representing the workspace from the input list of filenames.
