Detailed Description

A class tracking motions over time.

Whenever the object turns, or moves, internal counters will adjust their guessing of the objects traveled distance and current orientation.

Member Enumeration Documentation

anonymous enum [inherited]

Enumerator:

SUCCESS	Default return value of success.
ERR_UNSPEC	Unspecified error value - if no other fits.
ERR_NOMEM	Out of memory.
ERR_BUSY	Device or resource busy - try again later.
ERR_NOTIMPL	Function not implemented.
ERR_NETDOWN	Network is down.
ERR_HOSTUNREACH	No route to host.

Enumerator:

READY	Ready for returning a value.
NO_VALUE	There is no value available.
INACTIVE	Not yet enabled - implementation is inactive and cannot return meaningful values.
DATA_AVAILABLE	There is new data availbale.
