Class CollectorStreamBase<T>

Type Parameters:
T - Type of the value stored in the collection
All Implemented Interfaces:
Direct Known Subclasses:
CollectorStreamQuads, CollectorStreamTriples

public abstract class CollectorStreamBase<T> extends Object implements StreamRDF
Base class for StreamRDF implementations which store received <T> objects in a Collection. The resulting collection can be retrieved via the getCollected() method. Implementations are suitable for single-threaded parsing, for use with small data or distributed computing frameworks (e.g. Hadoop) where the overhead of creating many threads is significant.
