class ConstTrackStateType

#include <Acts/EventData/TrackStateType.hpp>

View type over a bitset stored in a 64 bit integer This view does not allow modifications.

Public Types

using raw_type = std::uint64_t

Public Functions

inline ConstTrackStateType(const raw_type &raw)

Constructor from a reference to the underlying value container.

Parameters: raw – the value container

inline bool test(std::size_t pos) const

Return if the bit at position pos is 1.

Parameters: pos – the bit position
Returns: if the bit at pos is one or not

Public Static Attributes

static constexpr std::size_t kRawBits = std::numeric_limits<std::make_unsigned<raw_type>::type>::digits

Private Members

const raw_type *m_raw = {nullptr}

inline TrackStateType(raw_type &raw)

Constructor from a reference to the underlying value container.

Parameters: raw – the value container

inline operator ConstTrackStateType(): Automatically convert to const track state type.

inline TrackStateType &operator=(const ConstTrackStateType &other)

Assign the value from another set of flags.

Parameters: other – the other set of flags to assign
Returns: this object

inline TrackStateType &operator=(const TrackStateType &other)

Assign the value from another set of flags.

Parameters: other – the other set of flags to assign
