- Method Detail
  - getFeatureSchema
```
FeatureSchema getFeatureSchema()
```
    Returns information about this FeatureCollection
    
    Returns:
    the types of the attributes of the features in this collection
  - getEnvelope
```
com.vividsolutions.jts.geom.Envelope getEnvelope()
```
    Returns the bounds of this collection.
    
    Returns:
    the smallest Envelope enclosing all the Features in this collection
  - size
```
int size()
```
    Returns the number of features in this collection.
    
    Returns:
    the number of features in this collection
  - isEmpty
```
boolean isEmpty()
```
    Returns whether this collection has no features.
    
    Returns:
    whether or not the size of this collection is 0
  - getFeatures
```
List getFeatures()
```
    Returns an unmodifiable List of the features in this collection
    
    Returns:
    a read-only view of all the features
  - iterator
```
Iterator iterator()
```
    Returns an Iterator over the features
    
    Returns:
    an Iterator over the features
  - query
```
List query(com.vividsolutions.jts.geom.Envelope envelope)
```
    A quick search for features, using an envelope comparison.
    
    Parameters:
    envelope - the envelope to query against
    
    Returns:
    features whose envelopes intersect the given envelope
  - add
```
void add(Feature feature)
```
    Adds a feature to this collection.
    
    Parameters:
    feature - a Feature to add to the end of this collection
  - addAll
```
void addAll(Collection features)
```
    Adds multiple features to this collection. To be preferred over #add for adding multiple features, because in some systems (like the JUMP Workbench) fewer events will be fired.
  - removeAll
```
void removeAll(Collection features)
```
    Removes multiple features from this collection. To be preferred over #remove for removing multiple features, because in some systems (like the JUMP Workbench) fewer events will be fired.
  - remove
```
void remove(Feature feature)
```
    Removes a feature from this collection.
    
    Parameters:
    feature - a Feature to remove from this collection
  - clear
```
void clear()
```
    Removes all features from this collection.
  - remove
```
Collection remove(com.vividsolutions.jts.geom.Envelope env)
```
    Removes the features which intersect the given envelope
    
    Returns:
    the removed features
