Constructor & Destructor Documentation

Pid()

erhic::Pid::Pid

(

Int_t

pdg = Pid::InvalidCode()

)

Constructor.

Parameters

[in]

pdg

The particle's PDG code, an integer

Definition at line 20 of file Pid.cxx.

~Pid()

erhic::Pid::~Pid ( )

virtual

Destructor.

Definition at line 24 of file Pid.cxx.

Member Function Documentation

Code()

Int_t erhic::Pid::Code ( ) const

inline

Returns the PDG code, an integer.

Definition at line 105 of file Pid.h.

Info()

TParticlePDG * erhic::Pid::Info

(

)

const

Returns the particle information object corresponding to this PDG code.

TODO May need to cache TParticlePDG* if performance proves too slow with database lookup upon each call.

From this, properties such as particle name, charge and mass can be accessed.

Definition at line 31 of file Pid.cxx.

InvalidCode()

Int_t erhic::Pid::InvalidCode ( )

static

Returns a code indicating 'not valid'.

Use this value to consistently indicate particles without an ID number.

Definition at line 44 of file Pid.cxx.

operator Int_t()

erhic::Pid::operator Int_t ( ) const

inline

Type conversion operator to integer PDG code.

int i = Pid(211) is equivalent to int i = Pid(211).Code();

Definition at line 103 of file Pid.h.

operator!=()

bool erhic::Pid::operator!= ( Int_t  i ) const

inline

Comparison operator with integer.

Compares the argument with this object's integer PDG code.

Definition at line 115 of file Pid.h.

operator<()

bool erhic::Pid::operator< ( Int_t  i ) const

inline

Comparison operator with integer.

Compares the argument with this object's integer PDG code.

Definition at line 111 of file Pid.h.

operator<=()

bool erhic::Pid::operator<= ( Int_t  i ) const

inline

Comparison operator with integer.

Compares the argument with this object's integer PDG code.

Definition at line 117 of file Pid.h.

operator==()

bool erhic::Pid::operator== ( Int_t  i ) const

inline

Comparison operator with integer.

Compares the argument with this object's integer PDG code.

Definition at line 109 of file Pid.h.

operator>()

bool erhic::Pid::operator> ( Int_t  i ) const

inline

Comparison operator with integer.

Compares the argument with this object's integer PDG code.

Definition at line 113 of file Pid.h.

operator>=()

bool erhic::Pid::operator>= ( Int_t  i ) const

inline

Comparison operator with integer.

Compares the argument with this object's integer PDG code.

Definition at line 119 of file Pid.h.

Set()

void erhic::Pid::Set ( Int_t  pdg )

inline

Sets the integer PDG code.

Parameters

[in]

pdg

The particle's PDG code, an integer

Definition at line 107 of file Pid.h.

Member Data Documentation

mCode

Int_t erhic::Pid::mCode

protected
