Constructor Detail

FeatureCollectionImpl

protected FeatureCollectionImpl(FeatureOwner owner,
                                org.w3c.dom.Element domElement,
                                GMLDocument document)

Calls the superclass constructor. This constructor should be called only from the method Feature.newFeature().

#see Feature.newFeature()

Method Detail

getFeatureIterator

public FeatureIterator getFeatureIterator()

Provides access to features owned by this FeatureOwner. Works only for features contained via featureMember element.

Specified by:

getFeatureIterator in interface FeatureOwner

Returns:

FeatureIterator that can be used for iterating on features.

toString

public java.lang.String toString()

Returns a one-line string description of this object.
