ucar.nc2.ft.point.PointIteratorFlatten

All Implemented Interfaces:

PointFeatureIterator

public class PointIteratorFlatten
extends PointIteratorAbstract

Adapt a PointFeatureCollectionIterator to a PointFeatureIterator, by flattening all the iterators in the collection into a single iterator over PointFeatures. Optionally add date and space filters.

Method Detail

setBufferSize

public void setBufferSize(int bytes)

Description copied from interface: PointFeatureIterator

Hint to use this much memory in buffering the iteration. No guarentee that it will be used by the implementation.

Parameters:

bytes - amount of memory in bytes

finish

public void finish()

Description copied from interface: PointFeatureIterator

Make sure that the iterator is complete, and recover resources. You must complete the iteration (until hasNext() returns false) or call finish(). may be called more than once.

hasNext

public boolean hasNext()
                throws IOException

Description copied from interface: PointFeatureIterator

Check if another PointFeature is available

Returns:

true if another PointFeature is available

Throws:

IOException - on i/o error

next

public PointFeature next()
                  throws IOException

Description copied from interface: PointFeatureIterator

Returns the next PointFeature. You must call hasNext() before calling next(), even if you know it will return true.

Returns:

the next PointFeature

Throws:

IOException - on i/o error
