Detailed Description

list of cones candidates.

We store in this class all the hash_elements and give functions to manipulate them.

Constructor & Destructor Documentation

siscone::hash_cones::hash_cones ( int  _Np,
double  _R2 
)

constructor with initialisation

Parameters
_Npnumber of particles
_R2cone radius (squared)

Definition at line 47 of file hash.cpp.

Member Function Documentation

int siscone::hash_cones::insert ( Cmomentum v,
Cmomentum parent,
Cmomentum child,
bool  p_io,
bool  c_io 
)

insert a new candidate into the hash.

Parameters
v4-momentum of te cone to add
parentparent particle defining the cone
childchild particle defining the cone
p_iowhether the parent has to belong to the cone or not
c_iowhether the child has to belong to the cone or not
Returns
0 on success, 1 on error

int siscone::hash_cones::insert ( Cmomentum v)

insert a new candidate into the hash.

Parameters
v4-momentum of te cone to add Note, in this case, we assume stability. We also assume that eta and phi are computed for v
Returns
0 on success, 1 on error

bool siscone::hash_cones::is_inside ( Cmomentum centre,
Cmomentum v 
)
inline

test if a particle is inside a cone of given centre.

check if the particle of coordinates 'v' is inside the circle of radius R centered at 'centre'.

Parameters
centrecentre of the circle
vparticle to test
Returns
true if inside, false if outside
