Detailed Description

An infinite line, similar to a CollisionRay, except that it extends in both directions.

It is, however, directional.

Constructor & Destructor Documentation

CollisionLine::CollisionLine

(

)

[inline]

Creates an invalid line.

This isn't terribly useful; it's expected that the user will subsequently adjust the line via set_origin()/set_direction() or set_from_lens().

[static, protected]

This function is called by the BamReader's factory when a new object of type CollisionLine is encountered in the Bam file.

It should create the CollisionLine and extract its information from the file.
