close
public void close()
Description copied from interface:FeatureIterator
Closes this iterator and releases any system resources associated with it.- Specified by:
close
in interfaceAutoCloseable
- Specified by:
close
in interfaceCloseable
- Specified by:
close
in interfaceFeatureIterator<SimpleFeature>
-
hasNext
public boolean hasNext()
Description copied from interface:FeatureIterator
Does another Feature exist in this Iteration.Iterator defin: Returns true if the iteration has more elements. (In other words, returns true if next would return an element rather than throwing an exception.)
- Specified by:
hasNext
in interfaceFeatureIterator<SimpleFeature>
- Returns:
- true if more Features exist, false otherwise.
-
prepareBuilderForNextFeature
protected boolean prepareBuilderForNextFeature(SimpleFeature f)
-
next
public SimpleFeature next() throws NoSuchElementException
Description copied from interface:FeatureIterator
Get the next Feature in this iteration.- Specified by:
next
in interfaceFeatureIterator<SimpleFeature>
- Returns:
- The next Feature
- Throws:
NoSuchElementException
- If no more Features exist.
-
hasElevations
protected boolean hasElevations(CoordinateSequence seq)
