FeatureType (Geotools modules 31-SNAPSHOT API)

All Superinterfaces:

AttributeType, ComplexType, PropertyType

All Known Subinterfaces:

SimpleFeatureType

All Known Implementing Classes:

ComplexFeatureTypeImpl, FeatureTypeImpl, FeatureTypeProxy, NonFeatureTypeProxy, SimpleFeatureTypeImpl, UniqueNameFeatureTypeImpl, VPFFeatureClass, VPFFeatureType
```
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.
