## Definition

The class `Straight_skeleton_2` provides a model for the `StraightSkeleton_2` concept which is the class type used to represent a straight skeleton.

The only purpose of this class is to protect all the modifying operations in a `HalfedgeDS`. Normal users should not modify a straight skeleton. If an advanced user needs to get access to the modifying operations, it must call the required methods through the `Base` class.

Is Model Of:

  `StraightSkeleton_2`

  `DefaultConstructible`

  `CopyConstructible`

  `Assignable`
