const SG::auxid_set_t & xAOD::AuxSelection::getSelectedAuxIDs

(

const SG::auxid_set_t &

fullset

)

const [virtual]

Return which variables were selected to be written out.

This function takes care of interpreting the options passed to ItemList in Athena, and TEvent in ROOT. It filters the list of variables passed to it, and returns the IDs of just the variables that should be written out.

Parameters:

fullset

The variables to be filtered based on the rules received

Returns:

The list of variables to be written out

void xAOD::AuxSelection::selectAux

(

const std::set< std::string > &

attributes

)

[virtual]

Select which variables should be written out.

Sets which variables should be selected from a store object. The formalism is the following:

• An empty set, or a set containing "*" will select all the dynamic attributes passed to the object.
• A single "-" attribute will not select any of the dynamic attributes.
• A set of variables (without "-" as the first character of the variable names) will select just the variables listed.
• A set of variable names, each prefixed by "-", will select all variables but the ones listed.

Parameters:

attributes

The attributes from ItemList or TEvent
