Class VPFFileStore

Object

ContentDataStore

VPFFileStore

All Implemented Interfaces:

DataAccess<SimpleFeatureType,SimpleFeature>, DataStore

public class VPFFileStore
extends ContentDataStore

A data store for VPF files. Any file can be retrieved from here. If you want joins (for example features with their geometries), you will have to look elsewhere. Hopefully some one will take advantage of this class to provide the full functionality.

Constructor Detail

VPFFileStore

public VPFFileStore(String vpfFilePath)
             throws IOException

Default constructor. Nothing special

Throws:

IOException

Method Detail

getVpfFilePath

public String getVpfFilePath()

getNames

public List<Name> getNames()

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.

See Also:

DataAccess.getNames()

getFeatureType

public SimpleFeatureType getFeatureType(ContentEntry entry)
                                 throws IOException

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.

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

getFeatureSource

public ContentFeatureSource getFeatureSource(String typeName)
                                      throws IOException

Description copied from class: ContentDataStore

Returns the feature source matching the specified name.

Subclasses should not implement this method. However overriding in order to perform a type narrowing to a subclasses of ContentFeatureSource is acceptable.

Specified by:

getFeatureSource in interface DataStore

Overrides:

getFeatureSource in class ContentDataStore

Parameters:

typeName - the feature type

Returns:

a SimpleFeatureSource (or possibly a subclass) providing operations for features of the specified type

Throws:

IOException - if data access errors occur

See Also:

DataStore.getFeatureSource(String)

getTypeSchema

public SimpleFeatureType getTypeSchema(String pathName)
                                throws IOException

Throws:

IOException

getFile

public VPFFile getFile(String pathName)
                throws IOException

Throws:

IOException

reset

public void reset()

Closes all of the opoen files and removes them from the collection of open files.
