Method Detail

getPointFeatureCollectionIterator

public PointFeatureCollectionIterator getPointFeatureCollectionIterator(int bufferSize)
                                                                 throws IOException

Description copied from interface: NestedPointFeatureCollection

Iterate through the collection, composed of PointFeatureCollection. Use this only if isMultipleNested() = false.

Specified by:

getPointFeatureCollectionIterator in interface NestedPointFeatureCollection

Overrides:

getPointFeatureCollectionIterator in class MultipleNestedPointCollectionImpl

Parameters:

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

Returns:

an iterator through PointFeatureCollection objects.

Throws:

IOException - on read error

hasNext

public boolean hasNext()
                throws IOException

Description copied from interface: SectionFeatureCollection

Use the internal iterator to check if there is another SectionFeature in the iteration.

Specified by:

hasNext in interface SectionFeatureCollection

Returns:

true is there is another SectionFeature in the iteration.

Throws:

IOException - on read error

next

public SectionFeature next()
                    throws IOException

Description copied from interface: SectionFeatureCollection

Use the internal iterator to get the next SectionFeature in the iteration. You must call hasNext() before you call this.

Specified by:

next in interface SectionFeatureCollection

Returns:

the next SectionFeature in the iteration

Throws:

IOException - on read error

resetIteration

public void resetIteration()
                    throws IOException

Description copied from interface: SectionFeatureCollection

Reset the internal iterator for another iteration over the SectionFeatures in this Collection.

Specified by:

resetIteration in interface SectionFeatureCollection

Throws:

IOException - on read error

subset

public SectionFeatureCollection subset(LatLonRect boundingBox)
                                throws IOException

Description copied from interface: NestedPointFeatureCollection

Get a subsetted NestedPointFeatureCollection based on a LatLonRect

Specified by:

subset in interface NestedPointFeatureCollection

Parameters:

boundingBox - spatial subset

Returns:

subsetted collection

Throws:

IOException - on i/o error
