Detailed Description

Set of flags pertaining a point of the track.

Template Parameters

FlagTraits

type with the definition of the flag values

recob::TrackTrajectory

The "flags" contain metadata pertaining a single point in a trajectory or track.

The metadata includes:

• a set of flags, including some for a trajectory, some specific to a fitted track, some reserved for future use and some available to the users
• an index pointing to the position of the hit in an originating trajectory, if such a trajectory exists. The specific convention to use this index must be documented by the using class (see recob::TrackTrajectory)

The meaning of the flags is described in the FlagTraits type. This type needs to provide a maxFlags() static constexpr method to express how many flags should be stored, d

bool recob::TrajectoryPointFlags::anySet ( Mask_t  mask ) const

inline

Returns whether any of the bits set in the mask are set.

Parameters

mask	mask with the bits to be checked defined and set (isSet())

Returns

whether any of the bits set in the mask are set

The method returns true if of all the flags that are set (Mask_t::isSet()) in mask, at least one is set. Flags of mask that are unset or undefined are ignored.
