assert_decision()

bool Trig::CacheGlobalMemory::assert_decision

(

)

const

checks if new event arrived with the decision Need to use before any call to CacheGlobalMemory.

It is marked const since it is frequently called from const methods and is internally locked.

Returns

true if all went fine about decision, false otherwise

creates new chain group

Parameters

patterns	list of patterns i.e. regexes, if chain groups already exists it is just given back The chain group is considered to exist if the patterns are the same. Patterns are stored and made unique i.e. "EF_mu4", "EF_mu6" is the same as "EF_mu6", "EF_mu4". It is not the same though as "EF_mu.*" even if in particular case that would mean the same 2 chains.
alias	is the short human readable name for the triggers which are in the group i.e. myMuons
props	are additional properties for the chain group creation (e.g. disable regex parsing)
