Examples of IServiceFactory

org.locationtech.udig.catalog.IServiceFactory
Builds *new* IService handle by using ServiceExtention to process provided connection parameters.
Please note that the *ID* associated with a set of connection parameters is the sole responsible of the individual ServiceExtention implementations (after all only ShpServiceExtention knows how to take connection parameters and determine a good identifier).
Connection parameters, and dragNdrop URLs, are only used as a guide:
- Information that was not used may be removed
- Authentication information (such as username and password) when we build a security plugin
- Where possible we make use of sensible defaults for missing information
We hope that for most uses client code will be able to store an ID directly and use it to look up a live resources in the Catalog. The use of IServiceFactory should be rare and unusual.
Using Connection Parameters to connect to an IService
If you are working with client code (such as a project file) that stores connection information directly please use IServiceFactory to create a IService handle and use the service.getID() to look up the live resource in the local catalog.
1. User supplied connection parameters
2. IServiceFactory.createService( parameters )
3. Process list of candidate services; allowing the user to choose if needed
4. Catalog findById( service.getIdentifier() )
  - if non null the service is already known (the returned service may not be in the location you expect; for example if the file has been moved and the catalog knows about it)
  - if null the catalog has never met this service before; use add( service ) to register it
5. service.getInfo( monitor ) to ensure the service can connect
  - If service.getStatus() == Status.BROKEN you can check service.getMessage() to find out why.
  - If service.getStatus() == Status.CONNECTED everything is good
Use Drag and Drop URLs to connect to an IService
Handling a drag and drop URL works in a similar manner; this time we have even less information to work with and it is much more likely that the user will need to choose between the available IService alternatives.
Also not that the IService handles returned may not have enough information to connect; a classic case is a security enabled WFS capabilities document. User involvement will be required. @since 1.0 Initial version caused some confusion over use of acquire @version 1.1 Explicitly broke generation of default parameters and creating a IService intoseparate steps @author Jody Garnett (Refractions Research)
