Method Detail

getName

public java.lang.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

getNestedPointFeatureCollectionIterator

public NestedPointFeatureCollectionIterator getNestedPointFeatureCollectionIterator(int bufferSize)
                                                                             throws java.io.IOException

Description copied from interface: NestedPointFeatureCollection

Iterate through the collection, composed of NestedPointFeatureCollection. Use this only if isMultipleNested() = true.

Specified by:

getNestedPointFeatureCollectionIterator in interface NestedPointFeatureCollection

Parameters:

bufferSize - how many bytes can be used to buffer data, use -1 to use default.

Returns:

an iterator through NestedPointFeatureCollection objects.

Throws:

Specified by:

flatten in interface NestedPointFeatureCollection

Parameters:

boundingBox - only points in this lat/lon bounding box. may be null.

dateRange - only points in this date range. may be null.

Returns:

a PointFeatureCollection, may be null if its empty.

Throws:

java.io.IOException - on read error
