Interface FeatureList

All Superinterfaces:

java.util.Collection, Feature, FeatureCollection, FeatureResults, java.util.List, ResourceCollection

All Known Subinterfaces:

FeatureDocument

All Known Implementing Classes:

AbstractFeatureList, SubFeatureList

public interface FeatureList

extends java.util.List, FeatureCollection

An ordered List of Features.

A FeatureList is usually retrived from a FeatureCollection with the subCollection( Filter ) operation. How you ask - make use of Filter 1.1 sortBy.

You may check to see if the result of subCollection( Filter ) is a FeatureList using an instanceof check. This often the case, when using not using sortBy the order is usually based on FID.

Method Detail

subList

public FeatureList subList(Filter filter)

Similar to subCollection, explicitly constructs a ordered List.

The list will be ordered:

• As indicated using Filter 1.1 sortBy
• occuring to their appearance in this FeatureList

Parameters:

filter -

Returns:

FeatureList based on features selected by filter
