| 3 | * Initialization of static fgCompare functions. At the moment a number of
|
|---|
| 4 | * functions TCompare*** are implemented (see BlockCompare.h).
|
|---|
| 5 | * Function TCompareXX sorts objects
|
|---|
| 6 | * by the variable "XX" that MUST be present in the data members of the
|
|---|
| 7 | * Block TRoot class.
|
|---|
| 8 | * By default most objects are sorted by PT or ET.
|
|---|
| 9 | * Only calorimeter cells and basic cluster are sorted by E
|
|---|
| 10 | * TRootGenParticle particle is not sorted by default
|
|---|
| 11 | * to preserve mother-dautherlinks between particles.
