-
class AnyCharge
- #include <Acts/EventData/Charge.hpp>
Charge and momentum interpretation for arbitrarily charged particles.
Only a charge magnitude identical to zero is interpreted as representing a neutral particle. This avoids ambiguities that might arise from using an approximate comparison with an arbitrary epsilon.
Public Functions
-
AnyCharge() = delete
Delete default constructor to ensure charge is always explicitely given.
-
template<typename T>
inline constexpr AnyCharge(T absQ) noexcept Construct with the magnitude of the input charge.
Private Members
-
float m_magnitude¶
-
AnyCharge() = delete
-
struct Neutral¶
- #include <Acts/EventData/Charge.hpp>
Charge and momentum interpretation for neutral particles.
-
struct SinglyCharged¶
- #include <Acts/EventData/Charge.hpp>
Charge and momentum interpretation for particles with +-e charge.
Public Functions
-
SinglyCharged() = default¶
Friends
-
inline friend constexpr bool operator==(SinglyCharged, SinglyCharged) noexcept¶
Compare for equality.
This is always
true
asSinglyCharged
has no internal state. Must be available to provide a consistent interface.
