public FeatureIterator<org.opengis.feature.Feature> features()
FeatureCollection
The implementation of Collection must adhere to the rules of
fail-fast concurrent modification. In addition (to allow for
resource backed collections, the close( Iterator )
method must be called.
This is almost equivalent to:
getAttribute(getFeatureType().getAttributeType(0).getName()).iterator();
.
Iterator<Feature>
FeatureIterator iterator=collection.features();
try {
while( iterator.hasNext() ){
Feature feature = iterator.next();
System.out.println( feature.getID() );
}
}
finally {
collection.close( iterator );
}
GML Note: The contents of this iterator are considered to be defined by featureMember tags (and/or the single allowed FeatureMembers tag). Please see getFeatureType for more details.

public org.opengis.feature.type.FeatureType getSchema()
FeatureCollection
There is a difference between getFeatureType() and getSchema()represents the LCD FeatureType that best represents the contents of this collection.
The method getSchema() is named for compatability with the geotools 2.0 API. In the Geotools 2.2 time frame we should be able to replace this method with a careful check of getFeatureType() and its attributes.

Collection is not guaranteed to be ordered in any manner.
The implementation of Collection must adhere to the rules of
fail-fast concurrent modification. In addition (to allow for
resource backed collections, the close( Iterator )
method must be called.
Example (safe) use:
Iterator iterator = collection.iterator();
try {
while( iterator.hasNext();){
Feature feature = (Feature) iterator.hasNext();
System.out.println( feature.getID() );
}
}
finally {
collection.close( iterator );
}

public void purge()
FeatureCollection
This method should be used with great caution, it is however available to allow the use of the ResourceCollection with algorthims that are unaware of the need to close iterators after use.
Example of using a normal Collections utility method:
Collections.sort( collection );
collection.purge();
