                      FeatureCollection featureCollection)
        Parameters:
        layerName - the name of the layer. A number will be appended if a layer with the same name already exists. Set to null to automatically generate a new name.

        Parameters:
        categoryName - name of the category where the Layer will be added
        layerName - the Layer name
        featureCollection - the new FeatureCollection which will be added or which will replace the one in the previous Layer named layerName if any

      • uniqueLayerName

        public String uniqueLayerName​(String name)

      • remove

        public void remove​(Layerable layerable)
        Convenience method. Use dispose rather than remove if you want to free the memory. remove is only used to temporarily remove a layer from the layer (ex. in the MoveLayerPlugIn).
        Parameters:
        layerable - Layerable to remove

      • remove

        public void remove​(Layerable[] layerables)
        remove, but do not dispose layer (as used e.g. by MoveLayerPlugin)

      • removeIfEmpty

        public void removeIfEmpty​(Category category)

      • dispose

        public void dispose()

      • dispose

        public void dispose​(Layerable l)

        public void dispose​(Layerable[] ls)

      • indexOf

        public int indexOf​(Category category)

      • setFiringEvents

        public boolean isFiringEvents()

      • reverseIterator

        public <T extends Layerable> Iterator<T> reverseIterator​(Class<T> layerableClass)
        Returns:
        an iterator over the layers, from bottom to top. Layers with #drawingLast = true appear last.

      • iterator

        public <T> Iterator<T> iterator​(Class<T> clazz)
        Returns:
        an iterator of layerables. Same as getLayerables but avoid building collections WARNING : old iterator() returning an iterator of Layers only has been removed and all classes using it in OpenJUMP core have been updated

      • getLayer

        public Layer getLayer​(String name)
        Returns:
        null if there is no such layer
