Constructor Detail

PointCollectionStreamAbstract

public PointCollectionStreamAbstract(String name)

Creates a feature collection with the specified name. DsgCollectionImpl.getTimeUnit() and DsgCollectionImpl.getAltUnits() will return default values until getPointFeatureIterator() is called for the first time.

Parameters:

name - the name of this feature collection. May be null.

PointCollectionStreamAbstract

public PointCollectionStreamAbstract(String name,
                                     CalendarDateUnit timeUnit,
                                     String altUnits)

Creates a feature collection with the specified name, time unit, and altitude unit.

Parameters:

name - the name of this feature collection. May be null.

timeUnit - the time unit. May not be null.

altUnits - the UDUNITS altitude unit string. May be null.

Method Detail

getInputStream

public abstract InputStream getInputStream()
                                    throws IOException

Returns the input stream from which to read point data.

Returns:

the input stream from which to read point data.

Throws:

IOException - if an I/O error occurs.

getPointFeatureIterator

public PointFeatureIterator getPointFeatureIterator()
                                             throws IOException

Description copied from interface: PointFeatureCollection

Get an iterator over the PointFeatures of this collection. call PointFeatureIterator.finish() when done

Returns:

iterator over the PointFeatures of this collection

Throws:

IOException - on read error
