Method Detail

findFeatureIds

Collection<String> findFeatureIds(BoundingBox horizontalExtent,
                                  Extent<Double> verticalExtent,
                                  Extent<org.joda.time.DateTime> timeExtent,
                                  Collection<String> variableIds)

Finds the IDs of features with the given spatio-temporal constraints. If any constraint is null it is considered to be unconstrained in that dimension.

Parameters:

horizontalExtent - The BoundingBox which features must have positions in.

verticalExtent - The vertical range which features must have positions in.

timeExtent - The time range which features must have positions in.

variableIds - The variable IDs which features must contain

Returns:

A Collection of IDs for features which match all of the given constraints

getAllFeatureIds

Set<String> getAllFeatureIds()

Returns:

All feature IDs present in this FeatureIndexer

addFeatures

void addFeatures(List<FeatureIndexer.FeatureBounds> features)

Adds features to this indexer. Features are defined in terms of FeatureIndexer.FeatureBounds objects which define the spatial boundaries of point features

Parameters:

features -
