FeatureSourceGeoResource
public class FeatureSourceGeoResource extends AbstractGeoResource (Code)
Resource implementation for resources which can map or resolve to a org.geotools.data.FeatureSource .
Subclasses may with to override the methods:

FeatureSourceGeoResource.createMetaData(FeatureSource,ProgressListener)
In addition, subclasses may wish to extend the following methods in order to support additional resolves.

FeatureSourceGeoResource.canResolve(Class)
FeatureSourceGeoResource.resolve(Class,ProgressListener)

Field Summary
GeoResourceInfo info

String name

DataStoreService parent

FeatureSource source


Constructor Summary
public FeatureSourceGeoResource(DataStoreService parent, String name)


Method Summary
public boolean canResolve(Class adaptee)
     Supports the required GeoResource resolves with an additional resolves to:

FeatureSourceGeoResource
FeatureType
DataStore

Subclasses may wish to extend this method.
protected GeoResourceInfo createMetaData(FeatureSource source, ProgressListener monitor)
     Creates the resource metadata.
Data providers providing custom metadata need to override this method.
protected FeatureSource featureSource(ProgressListener monitor)

protected FeatureType featureType(ProgressListener monitor)

public URI getIdentifier()
     Uses the parent identifer, and tacks FeatureSourceGeoResource.name on as a fragment.

metadata object

name
String name(Code)
Feature type name

parent
DataStoreService parent(Code)
Parent handle

source
FeatureSource source(Code)
Cached feature source

Constructor Detail
FeatureSourceGeoResource
public FeatureSourceGeoResource(DataStoreService parent, String name)(Code)

Method Detail
canResolve
public boolean canResolve(Class adaptee)(Code)
Supports the required GeoResource resolves with an additional resolves to:

FeatureSourceGeoResource
FeatureType
DataStore

Subclasses may wish to extend this method.

createMetaData
protected GeoResourceInfo createMetaData(FeatureSource source, ProgressListener monitor) throws IOException(Code)
Creates the resource metadata.
Data providers providing custom metadata need to override this method. The default implementation provided the following metadata mappings:

FeatureSource.getBounds -> GeoResourceInfo.getBounds
FeatureType.getTypeName -> GeoResourceInfo.getName
FeatureType#getNamespace()() -> GeoResourceInfo#getSchema()()

Parameters:
  source - the underlying FeatureSource
Parameters:
  monitor - a ProgressListener for blocking calls. The resource info.

featureSource
protected FeatureSource featureSource(ProgressListener monitor)(Code)

featureType
protected FeatureType featureType(ProgressListener monitor)(Code)

getIdentifier
public URI getIdentifier()(Code)
Uses the parent identifer, and tacks FeatureSourceGeoResource.name on as a fragment.

getInfo
public GeoResourceInfo getInfo(ProgressListener monitor) throws IOException(Code)

getName
public String getName()(Code)
The name of the feature source, feature type.

getStatus
public Status getStatus()(Code)
Returns the status of the handle based on the following. 1. If a non-null error has been set with FeatureSourceGeoResource.setMessage(Throwable) then the handle is Status.BROKEN . 2. If FeatureSourceGeoResource.source is non-null the handle is Status.CONNECTED . 3. The handle is Status.NOTCONNECTED .

resolve
public Object resolve(Class adaptee, ProgressListener monitor) throws IOException(Code)
Supports the required GeoResource resolves with an additional resolves to:

FeatureSourceGeoResource
FeatureType
DataStore

Subclasses may wish to extend this method.
