Interface FeatureType

All Superinterfaces:

AttributeType, ComplexType, PropertyType

All Known Subinterfaces:

SimpleFeatureType

All Known Implementing Classes:

public interface FeatureType
extends ComplexType

The type of a Feature.

Beyond a complex type, a feature defines some additional information:

• The default geometric attribute
• The coordinate referencing system (derived from the default geometry)

Method Detail

isIdentified

boolean isIdentified()

Features are always identified.

Specified by:

isIdentified in interface AttributeType

Returns:

true

See Also:

Attribute#getID()

getGeometryDescriptor

GeometryDescriptor getGeometryDescriptor()

Describe the default geometric attribute for this feature.

This method returns null in the case where no such attribute exists.

Returns:

The descriptor of the default geometry attribute, or null.

getCoordinateReferenceSystem

CoordinateReferenceSystem getCoordinateReferenceSystem()

The coordinate reference system of the feature.

This value is derived from the default geometry attribute:

   ((GeometryType)getDefaultGeometry().getType()).getCRS();
 

This method will return null in the case where no default geometric attribute is defined.

Returns:

The coordinate referencing system, or null.
