Method Detail

getSupportedCRSIdentifiers

public List<String> getSupportedCRSIdentifiers()

Returns of list of supported CRS identifiers. The first entry denotes the default CRS.

Returns:

A list of CRS identifiers (absolute URI values).

addCRSIdentifiers

public void addCRSIdentifiers(String... crsIdentifiers)

Adds the given sequence of identifiers to the list of supported coordinate reference systems.

Parameters:

crsIdentifiers - A sequence of CRS identifiers (absolute URI values that comply with OGC 09-048r3, 4.4).

getTypeName

public QName getTypeName()

Get the qualified name of the feature type.

Returns:

A QName object.

setTypeName

public void setTypeName(QName typeName)

Sets the feature type name.

Parameters:

typeName - A QName object.

isInstantiated

public boolean isInstantiated()

Indicates whether or not there are any instances of this feature type available in the data store.

Returns:

true if at least one feature instance exists; false otherwise.

setInstantiated

public void setInstantiated(boolean available)

Sets the availability of this feature type.

Parameters:

available - A boolean value indicating if any instances of this type are available in the data store.

getDefaultCRS

public String getDefaultCRS()

Gets the identifier of the default CRS for this feature type.

Returns:

A String representing a CRS reference (an absolute URI value).

getSpatialExtent

public org.opengis.geometry.Envelope getSpatialExtent()

Gets the geographic extent for the instances of this feature type. The spatial extent is typically set as follows:

1. using the first ows:WGS84BoundingBox element appearing in the WFS capabilities document;
2. from the valid area of the default CRS.

Returns:

An Envelope defining a bounding box.

setSpatialExtent

public void setSpatialExtent(org.opengis.geometry.Envelope geoExtent)

Sets the geographic extent of the feature instances. The CRS of the given envelope will be changed to the default CRS if necessary.

Parameters:

geoExtent - An envelope defining a bounding box in some CRS.

getSampleData

public File getSampleData()

Returns a File containing sample data. This is an XML entity where the document element is wfs:FeatureCollection.

Returns:

A File for reading the GML data, or null if no data are available.

setSampleData

public void setSampleData(File sampleData)

Sets the location of a sample data file containing instances of this feature type.

Parameters:

sampleData - A File object.

toString

public String toString()

Overrides:

toString in class Object

getTemporalExtent

public org.opengis.temporal.Period getTemporalExtent()

Gets the temporal extent for the instances of this feature type.

Returns:

A period representing a time interval, or null if the feature has no temporal properties.

setTemporalExtent

public void setTemporalExtent(org.opengis.temporal.Period period)

Sets the temporal extent of the feature instances.

Parameters:

period - A period representing a time interval.

getValidAreaOfCRS

org.geotoolkit.geometry.ImmutableEnvelope getValidAreaOfCRS(String crsRef)

Creates an envelope representing the valid area of use for the specified coordinate reference system (CRS).

Parameters:

crsRef - An absolute URI ('http' or 'urn' scheme) that identifies a CRS in accord with OGC 09-048r3.

Returns:

An ImmutableEnvelope defining the domain of validity for the CRS, or null if no CRS definition can be found.
