Method Detail

getName

public String getName()

Description copied from interface: FeatureCollection

Get the name of this feature collection.

Specified by:

getName in interface FeatureCollection

Returns:

the name of this feature collection

size

public int size()

Description copied from interface: NestedPointFeatureCollection

The number of elements in the collection. May not be known until after iterating through the collection.

Specified by:

size in interface NestedPointFeatureCollection

Returns:

number of elements in the collection, or -1 if not known.

setSize

protected void setSize(int npts)

isMultipleNested

public boolean isMultipleNested()

Description copied from interface: NestedPointFeatureCollection

If true, use getNestedPointFeatureCollectionIterator, otherwise use getPointFeatureCollectionIterator.

Specified by:

isMultipleNested in interface NestedPointFeatureCollection

Returns:

if multiple nested

getCollectionFeatureType

public FeatureType getCollectionFeatureType()

Description copied from interface: FeatureCollection

All features in this collection have this feature type

Specified by:

getCollectionFeatureType in interface FeatureCollection

Returns:

the feature type

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
