Constructor Detail

VPFLibrary

public VPFLibrary(SimpleFeature libraryFeature,
                  File dir,
                  URI namespace)
           throws IOException,
                  SchemaException

Constructor which defaults the containing database to null and looks up the first (and presumably only) entry in the library attribute table

Parameters:

dir - the containing directory

namespace - the namespace to create features with.

Throws:

SchemaException - For problems making one of the feature classes as a FeatureType.

IOException

Method Detail

getCoverages

public List<VPFCoverage> getCoverages()

Returns the coverages contained by the library

Returns:

a List value which contains VPFCoverage objects

getXmax

public double getXmax()

Getter for property xmax.

Returns:

Value of property xmax.

getXmin

public double getXmin()

Getter for property xmin.

Returns:

Value of property xmin.

getYmax

public double getYmax()

Getter for property ymax.

Returns:

Value of property ymax.

getYmin

public double getYmin()

Getter for property ymin.

Returns:

Value of property ymin.

toString

public String toString()

Overrides:

toString in class Object

getTileMap

public Map<Short,String> getTileMap()

Returns a map containing the tiles used by this library. The map has Short keys and and string values.

Returns:

a Map value

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 VPFFeatureType 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(Name typeName,
                                             Transaction tx)
                                      throws IOException

Description copied from class: ContentDataStore

Returns the feature source matching the specified name and explicitly specifies a transaction.

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

Overrides:

getFeatureSource in class ContentDataStore

Throws:

IOException

See Also:

DataStore.getFeatureSource(String)

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)

getDirectory

public File getDirectory()

getTypeSchema

public SimpleFeatureType getTypeSchema(String typeName)
                                throws IOException

Throws:

IOException

getCoordinateReferenceSystem

public CoordinateReferenceSystem getCoordinateReferenceSystem()

Returns the coordinate reference system appropriate for this library. If the coordinate reference system cannot be determined null will be returned.
