 org.geotools.feature.collection.FeatureState
All known Subclasses: org.geotools.feature.collection.BaseFeatureState, org.geotools.feature.collection.SubFeatureState,
| FeatureState | | abstract public class FeatureState (Code) | | This is *not* a Feature - it is a Delegate used by FeatureCollection
implementations as "mix-in", provides implementation of featureCollection
events, featureType, and attribute access.
To use cut&paste the following code exactly:
On the bright side this means we can "fix" all the FeatureCollection implementations
in one fell-swoop.

| bounds | | protected Envelope bounds(Code) | | |
| addListener | | abstract public void addListener(CollectionListener listener)(Code) | | Adds a listener for collection events.
Parameters:
listener - The listener to add |
| fids | | public static Set fids(Collection stuff)(Code) | | Get the set of fids for the provided collection.
By doing a quick pass through the collection we can do
comparisons based on Feature ID (rather then collection
membership).
A subclass that tracks its FID information may wish to override
this method.
|
| fireChange | | abstract protected void fireChange(Feature[] features, int type)(Code) | | To let listeners know that something has changed.
|
| fireChange | | protected void fireChange(Feature feature, int type)(Code) | | |
| getBounds | | public Envelope getBounds()(Code) | | Gets the bounding box for the features in this feature collection.
the envelope of the geometries contained by this featurecollection. |
| getDefaultGeometry | | public Geometry getDefaultGeometry()(Code) | | |
| getNumberOfAttributes | | public int getNumberOfAttributes()(Code) | | |
| isFeatures | | public static boolean isFeatures(Collection stuff)(Code) | | Test if collection is all features!
|
| removeListener | | abstract public void removeListener(CollectionListener listener)(Code) | | Removes a listener for collection events.
Parameters:
listener - The listener to remove |
