Method Detail

canResolve

public boolean canResolve(java.lang.Class adaptee)

Description copied from interface: Resolve

Non blocking method which is used to determine if a resolve into an instance of a particular class is supported.

Parameters:

adaptee - Class of object to resolve into.

Returns:

true if a resolution for adaptee is avaialble

resolve

public java.lang.Object resolve(java.lang.Class adaptee,
                                ProgressListener monitor)
                         throws java.io.IOException

Description copied from interface: Service

Will attempt to morph into the adaptee, and return that object. Required adaptions:

• IServiceInfo.class
• List.class

May Block.

Parameters:

adaptee -

monitor -

Returns:

instance of adaptee, or null if unavailable (IServiceInfo and List must be supported)

Throws:

java.io.IOException

ServiceInfo, GeoResource, IResolve#resolve(Class, ProgressListener)

getInfo

public ServiceInfo getInfo(ProgressListener monitor)
                    throws java.io.IOException

Returns:

IServiceInfo resolve(IServiceInfo.class,ProgressListener monitor);

Throws:

java.io.IOException

See Also:

IService#resolve(Class, ProgressListener)

getDataStore

protected ShapefileDataStore getDataStore(ProgressListener monitor)
                                   throws java.io.IOException

Throws:

java.io.IOException

members

public java.util.List members(ProgressListener monitor)
                       throws java.io.IOException

Description copied from interface: Service

Return list of IGeoResources managed by this service. This method must return the same result as the following:

   
   (List)resolve(List.class,monitor);
   
 

Many file based serivces will just contain a single IGeoResource.

Returns:

A list of type GeoResource.

Throws:

java.io.IOException

getConnectionParams

public java.util.Map getConnectionParams()

Description copied from interface: Service

Accessor to the set of params used to create this entry. There is no guarantee that these params created a usable service (@see getStatus() ). These params may have been modified within the factory during creation. This method is intended to be used for cloning (@see IServiceFactory) or for persistence between sessions.

Returns:

A map with key of type String, and value of type Serializable.

ServiceFinder

getStatus

public Resolve.Status getStatus()

Description copied from interface: Resolve

Status of the resolve. Resolving into other types of objects often involves connecting to a remote service or resource. This method is provided to indicate the state of any connections.

Returns:

One of Resolve.Status.BROKEN,Resolve.Status.CONNECTED, or Resolve.Status.NOTCONNECTED.

getMessage

public java.lang.Throwable getMessage()

Description copied from interface: Resolve

In the event that an error occurs during a resolve, that error can be reported back with this method. This method returns a value when Resolve.getStatus() returns Resolve.Status.BROKEN, otherwise it return null.

Returns:

An exception that occured during a resolve, otherwise null.

getIdentifier

public java.net.URI getIdentifier()

Description copied from interface: Resolve

Returns a URI which uniqley identifies the Resolve.

Returns:

Id of the Resolve, should never be null.
