Class PointIteratorFromStructureData
java.lang.Object
ucar.nc2.ft.point.PointIteratorAbstract
ucar.nc2.ft.point.PointIteratorFromStructureData
- All Implemented Interfaces:
- PointFeatureIterator
- Direct Known Subclasses:
- StandardPointFeatureIterator
public abstract class PointIteratorFromStructureData
- extends PointIteratorAbstract
A PointFeatureIterator which uses a StructureDataIterator to iterate over members of a Structure,
with optional filtering and calculation of time range and bounding box.
Subclass must implement makeFeature() to turn the StructureData into a PointFeature.

PointIteratorFromStructureData
public PointIteratorFromStructureData(StructureDataIterator structIter,
PointIteratorAbstract.Filter filter)
throws IOException
- Throws:
IOException
makeFeature
protected abstract PointFeature makeFeature(int recnum,
StructureData sdata)
throws IOException
- Throws:
IOException
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
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.
