Method Details

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)

getInfo

public ServiceInfo getInfo()

Description copied from interface: DataAccess

Information about this service.

This method offers access to a summary of header or metadata information describing the service. Subclasses may return a specific ServiceInfo instance that has additional information (such as FilterCapabilities).

Specified by:

getInfo in interface DataAccess<SimpleFeatureType,SimpleFeature>

Overrides:

getInfo in class ContentDataStore

Returns:

SeviceInfo

setNamespaceURI

public void setNamespaceURI(String namespaceURI)

Description copied from class: ContentDataStore

Sets the namespace uri of the datastore.

This will be used to qualify the entries or types of the datastore.

Overrides:

setNamespaceURI in class ContentDataStore

Parameters:

namespaceURI - The namespace uri, may be null.

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.

getNames

public List<Name> getNames()
                    throws IOException

Description copied from class: ContentDataStore

Returns the same list of names than ContentDataStore.getTypeNames() meaning the returned Names have no namespace set.

Specified by:

getNames in interface DataAccess<SimpleFeatureType,SimpleFeature>

Overrides:

getNames in class ContentDataStore

Returns:

Names of the available contents.

Throws:

IOException

See Also:

• DataAccess.getNames()

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

removeSchema

public void removeSchema(Name typeName)
                  throws IOException

Description copied from interface: DataAccess

Used to permanently remove a schema from the underlying storage

This functionality is similar to an "drop table" statement in SQL. Implementation is optional; it may not be supported by all servers or files.

Specified by:

removeSchema in interface DataAccess<SimpleFeatureType,SimpleFeature>

Overrides:

removeSchema in class ContentDataStore

Throws:

IOException - if the operation failed

See Also:

• DataAccess.removeSchema(Name)

removeSchema

public void removeSchema(String typeName)
                  throws IOException

Description copied from interface: DataStore

Used to permanently remove a schema from the underlying storage

This functionality is similar to an "drop table" statement in SQL. Implementation is optional; it may not be supported by all servers or files.

Specified by:

removeSchema in interface DataStore

Overrides:

removeSchema in class ContentDataStore

Throws:

IOException - if the operation failed

See Also:

• DataStore.removeSchema(String)
