Member Function Documentation

insert() [1/2]

int siscone_spherical::sph_hash_cones::insert

(

CSphmomentum *

v

)

insert a new candidate into the hash.

Parameters

v	4-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

Definition at line 169 of file hash.cpp.

insert() [2/2]

int siscone_spherical::sph_hash_cones::insert	(	CSphmomentum *	v,
		CSphmomentum *	parent,
		CSphmomentum *	child,
		bool	p_io,
		bool	c_io
	)

insert a new candidate into the hash.

Parameters

v	4-momentum of te cone to add
parent	parent particle defining the cone
child	child particle defining the cone
p_io	whether the parent has to belong to the cone or not
c_io	whether the child has to belong to the cone or not

Returns

0 on success, 1 on error
