ucar.nc2.ft.point.PointIteratorAdapter

All Implemented Interfaces:

java.io.Closeable, java.lang.AutoCloseable, java.util.Iterator<PointFeature>, PointFeatureIterator

public class PointIteratorAdapter
extends PointIteratorAbstract

Adapts an Iterator<PointFeature> to a PointFeatureIterator. The original iterator gains bounds calculation and compatibility with the rest of the Point Feature API.

Constructor Detail

PointIteratorAdapter

public PointIteratorAdapter(java.util.Iterator<? extends PointFeature> pointIter)

Creates a PointFeatureIterator from the supplied basic iterator.

Parameters:

pointIter - a basic iterator over point features.

Method Detail

hasNext

public boolean hasNext()

Returns true if the iteration has more elements. (In other words, returns true if next() would return an element rather than throwing an exception.)

This method is idempotent, meaning that when it is called repeatedly without an intervening next(), calls after the first will have no effect.

Returns:

true if the iteration has more elements, false otherwise. A false return value finishes this iteration.

next

public PointFeature next()
                  throws java.util.NoSuchElementException

Returns the next element in the iteration.

Returns:

the next element in the iteration

Throws:

java.util.NoSuchElementException - if the iteration has no more elements.

close

public void close()

Finishes bounds calculation, if it has been enabled. Do not attempt to retrieve bounds information before this method has been invoked or hasNext() returns false.

This method is idempotent, meaning that calls after the first have no effect.
