Method Detail

close

void close()

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

toCollection

FeatureCollection toCollection()

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.

Returns:

members as feature collection, never null
