Detailed Description

A 2D point on a given set of layers and belonging to a certain net, that links together a number of board items.

A hash table of joints is used by the router to follow connectivity between the items.

Definition at line 42 of file pns_joint.h.

Member Typedef Documentation

◆ LINKED_ITEMS

Joints are hashed by their position, layers and net.

Linked items are, obviously, not hashed.

◆ Collide()

bool PNS::ITEM::Collide ( const ITEM aOther,

Check for a collision (clearance violation) with between us and item aOther.

Collision checking takes all PCB stuff into account (layers, nets, DRC rules). Optionally returns a minimum translation vector for force propagation algorithm.

Parameters
aOtheris the item to check collision against.
Returns
true, if a collision was found.
