Method Detail

getFilterCapabilities

public FilterCapabilities getFilterCapabilities()

createSchema

public void createSchema(SimpleFeatureType incoming)
                  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:

incoming - FetureType to add to DataStore

Throws:

IOException - If featureType cannot be created

See Also:

DataAccess.createSchema(FeatureType)

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.

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

getFeatureWriter

public FeatureWriter<SimpleFeatureType,SimpleFeature> getFeatureWriter(String typeName,
                                                                       Filter filter,
                                                                       Transaction tx)
                                                                throws IOException

Description copied from class: ContentDataStore

Returns a feature writer for the specified query and transaction.

This method is not intended to be overridden and is marked final. This implementation delegates to FeatureCollection and wraps an iterator in a FeatureWriter.

Specified by:

getFeatureWriter in interface DataStore

Overrides:

getFeatureWriter in class ContentDataStore

Parameters:

typeName - the type name for features that will be accessible

filter - defines additional constraints on the features that will be accessible

tx - the transation that the returned writer operates against

Returns:

an instance of FeatureWriter

Throws:

IOException - if data access errors occur

See Also:

DataStore.getFeatureWriterAppend(String, Transaction)

createContentState

protected ContentState createContentState(ContentEntry entry)

Description copied from class: ContentDataStore

Instantiates a new content state for the entry.

Subclasses may override this method to return a specific subclass of ContentState.

Overrides:

createContentState in class ContentDataStore

Parameters:

entry - The entry.

Returns:

A new instance of ContentState for the entry.

dispose

public void dispose()

Description copied from interface: DataAccess

Disposes of this data store and releases any resource that it is using.

A DataStore cannot be used after dispose has been called, neither can any data access object it helped create, such as FeatureReader, FeatureSource or FeatureCollection.

This operation can be called more than once without side effects.

There is no thread safety assurance associated with this method. For example, client code will have to make sure this method is not called while retrieving/saving data from/to the storage, or be prepared for the consequences.

Specified by:

dispose in interface DataAccess<SimpleFeatureType,SimpleFeature>

Overrides:

dispose in class ContentDataStore
