updateEnabledState

protected void updateEnabledState()

Description copied from class: JosmAction

Override in subclasses to update the enabled state of the action when something in the JOSM state changes, i.e. when a layer is removed or added. See JosmAction.updateEnabledState(Collection) to respond to changes in the collection of selected primitives. Default behavior is empty.

Overrides:

updateEnabledState in class JosmAction

updateEnabledState

protected void updateEnabledState(Collection<? extends OsmPrimitive> selection)

Description copied from class: JosmAction

Override in subclasses to update the enabled state of the action if the collection of selected primitives changes. This method is called with the new selection.

Overrides:

updateEnabledState in class JosmAction

Parameters:

selection - the collection of selected primitives; may be empty, but not null

JosmAction.updateEnabledState(), JosmAction.initEnabledState()

allowRegularPolygon

protected boolean allowRegularPolygon(Collection<Node> nodes)

Determines if a regular polygon is allowed to be created with the given nodes collection.

Parameters:

nodes - The nodes collection to check.

Returns:

true if all nodes in the given collection are referred by the same object, and no other one (see #8431)
