Method Detail

getPointFeatureIterator

public PointFeatureIterator getPointFeatureIterator(int bufferSize)
                                             throws java.io.IOException

Description copied from interface: PointFeatureCollection

Get an iterator over the PointFeatures of this collection

Parameters:

bufferSize - how many bytes can be used to buffer data, use -1 to use default.

Returns:

iterator over the PointFeatures of this collection

Throws:

java.io.IOException - on read error

subset

public PointFeatureCollection subset(LatLonRect boundingBox,
                                     DateRange dateRange)
                              throws java.io.IOException

Description copied from interface: PointFeatureCollection

Subset this collection by boundingBox and/or dateRange

Specified by:

subset in interface PointFeatureCollection

Overrides:

subset in class PointCollectionImpl

Parameters:

boundingBox - only points in this lat/lon bounding box. may be null.

dateRange - only points in this date range. may be null.

Returns:

subsetted collection, may be null if empty

Throws:

java.io.IOException - on read error
