- Method Detail
  - getIdentifier
```
public FeatureId getIdentifier()
```
    Description copied from interface: Feature
    
    A unique identifier for the feature.
    getType().isIdentifiable() must return true so this value must not return null.
    Generation of the identifier is dependent on the underlying data storage medium. Often this identifier is not persistent. Mediums such shapefiles and database tables have "keys" built in which map naturally to persistent feature identifiers. But other mediums do not have such keys and may have to generate feature identifiers "on-the-fly". This means that client code being able to depend on this value as a persistent entity is dependent on which storage medium or data source is being used.
    
    Specified by:
    
    getIdentifier in interface Attribute
    
    Specified by:
    
    getIdentifier in interface Feature
    
    Returns:
    
    The feature identifier, never null.
  - getID
```
public String getID()
```
    Description copied from interface: SimpleFeature
    
    Unique Identifier for the SimpleFeature
    This value is non-null and should be the same as getIdentifier().toString(). Please note that an ID may be provided
    
    Specified by:
    
    getID in interface SimpleFeature
    
    Returns:
    
    A unique identifier for the attribute, or null if the attribute is non-identifiable.

    In the case that the feature has no geometric attributes this method should return an empty bounds, ie, bounds.isEmpty() == true. This method should never return null.
    The coordinate reference system of the returned bounds is derived from the geometric attributes which were used to compute the bounds. In the event that the feature contains multiple geometric attributes which have different crs's, the one defined by #getGeometryDescriptor() should take precedence and the others should be reprojected accordingly.

    Returns a subset of the properties of the complex attribute which match the specified name.
    This method is a convenience for ComplexAttribute.getProperties(Name) in which Name.getNamespaceURI() is null.
    Note: Special care should be taken when using this method in the case that two properties with the same local name but different namespace uri exist. For this reason using ComplexAttribute.getProperties(Name) is safer.
    
    Specified by:
    
    getProperties in interface ComplexAttribute
    
    Parameters:
    
    name - The local name of the properties to return.

```
    Description copied from interface: ComplexAttribute

    This method is a convenience for ComplexAttribute.getProperty(Name) in which Name.getNamespaceURI() is null.
    Note: This method is a convenience and care should be taken when calling it if more then a single property matches name. In such a case the first encountered property in which Property.getName() is matches name is returned, and no order is guaranteed.
    Note: Special care should be taken when using this method in the case that two properties with the same local name but different namespace uri exist. For this reason using ComplexAttribute.getProperties(Name) is safer.
