protected java.lang.Object createTool()

Description copied from class: ToolController

Consturucts the tool when it does not already exist.

This method should be called only if the ToolController.getTool() method returns null, and it should not normally be called directly. Call ToolController.setTool() instead, or use a method that calls ToolController.setTool(), such as ToolController.ensureTool().

That ensures that createTool is called only once per ToolController and that the controller remembers the tool so that ToolController.getTool() can return it. Note, however, that it is not strictly necessary for createTool to construct a new object. In some cases, it might return an existing object that has not yet been made known to this ToolController. For example, if two different frames share a tool, they would have separate ToolManagers and separate ToolControllers for the same tool object, but at most one of those controllers should construct a new tool object.
