static bool Collision::predicate	(	const Collision *	c1,
		const Collision *	c2

Predicate for duplicate removal

virtual void Collision::collide ( ) [pure virtual]

Simulate a collision and update object properties

Implemented in BallCollision, and BorderCollision.

bool Collision::isAffected ( Collision * another ) [inline]

Test if this collision is affected by another collision. A collision is affected if it happens after another collision and one of the objects is contained in the other collision too

References first, and second.

std::string Collision::dump ( ) const

Write to stream

Definition at line 16 of file Collision.cpp.

References first, Object::name(), second, and time.
