Method Detail

close

public void close()

Description copied from interface: FeatureResultSet

Must be invoked after using to close underlying resources, e.g. SQL ResultSets.

Specified by:

close in interface FeatureResultSet

toCollection

public FeatureCollection toCollection()

Description copied from interface: FeatureResultSet

Returns all members of the FeatureResultSet as a FeatureCollection.

NOTE: This method should not be called for very large result sets, as it introduces the overhead of keeping all created feature instances in memory. The returned collection will contain all Features instances from the current position in the iteration sequence.

Specified by:

toCollection in interface FeatureResultSet

Returns:

members as feature collection, never null

iterator

public java.util.Iterator<Feature> iterator()

Specified by:

iterator in interface java.lang.Iterable<Feature>
