      • getDataSourceBounds

        public static java.util.List<Bounds> getDataSourceBounds​(java.util.Collection<DataSource> dataSources)

        Replies the list of data source bounds.

        Dataset maintains a list of data sources which have been merged into the data set. Each of these sources can optionally declare a bounding box of the data it supplied to the dataset.

        This method replies the list of defined (non null) bounding boxes.

        Parameters:
        dataSources - list of data sources
        Returns:
        the list of data source bounds. An empty list, if no non-null data source bounds are defined.
