GroupAnnotation (Cytoscape Swing App API (swing-app-api) 3.8.1 API)

All Superinterfaces:

Annotation
```
public interface GroupAnnotation
extends Annotation
```
The GroupAnnotation is a container for a collection of annotations that should be grouped together.

A GroupAnnotation may contain members from either the foreground or background canvas. Changing the canvas of the GroupAnnotation itself will not automatically set its members to the same canvas, each annotation must have its setCanvas() method called individually.

The z-order of member annotations will automatically be set so that the annotations are adjacent within the same canvas. The AnnotationManager is free to change the z-order of annotations in order to maintain this property.
Module: presentation-api

</dependency>

Cytoscape Backwards Compatibility (API Interface): We expect that this interface will be used but not implemented by developers using this interface. As such, we reserve the right to add methods to the interface as part of minor version upgrades. We will not remove methods for any changes other than major version upgrades.
