  • Constructor Details

    • FeatureDataset

      public FeatureDataset(Collection<Feature> newFeatures, FeatureSchema featureSchema)
      Creates a FeatureDataset, initialized with a group of Features.
      Parameters:
      newFeatures - an initial group of features to add to this FeatureDataset
      featureSchema - the types of the attributes of the features in this collection

    • FeatureDataset

      public FeatureDataset(FeatureSchema featureSchema)
      Creates a FeatureDataset.
      Parameters:
      featureSchema - the types of the attributes of the features in this collection

  • Method Details

    • getFeature

      public Feature getFeature(int index)

      Specified by:
      getFeatures in interface FeatureCollection
      Returns:
      a read-only view of all the features

    • isEmpty

      public boolean isEmpty()
      Description copied from interface: FeatureCollection
      Returns whether this collection has no features.
      Specified by:
      isEmpty in interface FeatureCollection
      Returns:
      whether or not the size of this collection is 0

    • query

      public List<Feature> query(org.locationtech.jts.geom.Envelope envelope)
      Description copied from interface: FeatureCollection
      A quick search for features, using an envelope comparison.

      Parameters:
      envelope - the envelope to query against
      Returns:
      a List containing the features whose envelopes intersect the given envelope

    • contains

      public boolean contains(Feature feature)
      Returns whether or not this Feature is in this collection
      Returns:
      true if this feature is in this collection, as determined using Feature#equals

    • remove

      public Collection<Feature> remove(org.locationtech.jts.geom.Envelope env)
      Removes the features which intersect the given envelope

      clear in interface FeatureCollection

    • size

      public int size()
      Description copied from interface: FeatureCollection
      Returns the number of features in this collection.
      Specified by:
      size in interface FeatureCollection
      Returns:
      the number of features in this collection

    • iterator

      public Iterator<Feature> iterator()
      Description copied from interface: FeatureCollection
      Returns an Iterator over the features

    • addAll

      public void addAll(Collection<Feature> features)
      Description copied from interface: FeatureCollection
      Adds multiple features to this collection. To be preferred over #add for adding multiple features, because in some systems (like the JUMP Workbench) fewer events will be fired.

    • removeAll

      public void removeAll(Collection<Feature> c)
      Description copied from interface: FeatureCollection
