Detailed Description

This subclass of Contact represents a pair of contact surfaces that are not yet being tracked; there is no ContactId for them.

We don't yet know what kind of Contact object would be appropriate for them, so this is a placeholder until a ContactTracker replaces it with something meaningful. The contact condition for one of these is always "Untracked".

Constructor & Destructor Documentation

SimTK::UntrackedContact::UntrackedContact ( )
inline

Default constructor creates an empty handle.

SimTK::UntrackedContact::UntrackedContact ( ContactSurfaceIndex  surf1,
ContactSurfaceIndex  surf2 
)

Create an UntrackedContact object.

Parameters
surf1the index of the first surface involved in the contact, specified by its index within its contact set
surf2the index of the second surface involved in the contact, specified by its index within its contact set

Member Function Documentation

static bool SimTK::UntrackedContact::isInstance ( const Contact contact)
static

Determine whether a Contact object is an UntrackedContact.

static ContactTypeId SimTK::UntrackedContact::classTypeId ( )
static

Obtain the unique small-integer id for the UntrackedContact class.
