Method Detail

createFeatureSource

protected ContentFeatureSource createFeatureSource(ContentEntry entry)
                                            throws IOException

Description copied from class: ContentDataStore

Instantiates new feature source for the entry.

Subclasses should override this method to return a specific subclass of ContentFeatureSource.

Specified by:

createFeatureSource in class ContentDataStore

Parameters:

entry - The entry.

Returns:

An new instance of ContentFeatureSource for the entry.

Throws:

IOException

createTypeNames

protected List<Name> createTypeNames()
                              throws IOException

Description copied from class: ContentDataStore

Creates a set of qualified names corresponding to the types that the datastore provides.

Namespaces may be left null for data stores which do not support namespace qualified type names.

Specified by:

createTypeNames in class ContentDataStore

Returns:

A list of Name.

Throws:

IOException - Any errors occuring connecting to data.

createSchema

public void createSchema(SimpleFeatureType featureType)
                  throws IOException

Description copied from class: ContentDataStore

Creates a new schema in the datastore.

This implementation throws aUnsupportedOperationException. Subclasses should override to support schema creation.

Specified by:

createSchema in interface DataAccess<SimpleFeatureType,SimpleFeature>

Overrides:

createSchema in class ContentDataStore

Parameters:

featureType - FetureType to add to DataStore

Throws:

IOException - If featureType cannot be created

See Also:

DataAccess.createSchema(FeatureType)

getSchema

public SimpleFeatureType getSchema()
                            throws IOException

Description copied from interface: FileDataStore

FeatureType for the file being read.

This is the same as getSchema( getTypeName[0] )

Specified by:

getSchema in interface FileDataStore

Returns:

FeatureType of the file being read

Throws:

IOException

See Also:

DataStore.getSchema(java.lang.String)

updateSchema

public void updateSchema(SimpleFeatureType featureType)
                  throws IOException

Specified by:
