Notation used in Ruby API documentation
Module: db
Description: An edge class
An edge is a connection between points, usually participating in a larger context such as a polygon. An edge has a defined direction (from p1 to p2). Edges play a role in the database as parts of polygons and to describe a line through both points. The Edge object is also used inside the boolean processor (EdgeProcessor). Although supported, edges are rarely used as individual database objects.
See The Database API for more details about the database objects like the Edge class.

_destroy | Signature: void _destroy Description: Explicitly destroys the object Explicitly destroys the object on C++ side if it was owned by the script interpreter. Subsequent access to this object will throw an exception. If the object is not owned by the script, this method will do nothing. | |||||
_destroyed? | Signature: [const] bool _destroyed? Description: Returns a value indicating whether the object was already destroyed This method returns true, if the object was destroyed, either explicitly or by the C++ side.

This method may be called if an object is returned from a C++ function and the object is known not to be owned by any C++ instance. If necessary, the script side may delete the object if the script's reference is no longer required. Usually it's not required to call this method. It has been introduced in version 0.24. | |||||
_unmanage | Signature: void _unmanage Description: Marks the object as no longer owned by the script side. Calling this method will make this object no longer owned by the script's memory management.

Technically speaking, this method will turn the script's reference into a weak reference. After the script engine decides to delete the reference, the object itself will still exist. If the object is not managed otherwise, memory leaks will occur. Usually it's not required to call this method. It has been introduced in version 0.24. | |||||
