AlgorithmIdentifier Class Reference

Small structure to hold an algorithm's name and store, plus some details on its EventView. The AI also keeps a pointer to the EventContext and MsgService, this is for convenience such that methods which use the AI don't need to be additionally passed these. More...

Member Data Documentation

m_caller

std::string AlgorithmIdentifier::m_caller

Name of the algorithm.

Definition at line 33 of file AlgorithmIdentifier.h.

m_hash

size_t AlgorithmIdentifier::m_hash

Hash of algorithm + store + realSlot.

Multi-event-unique quantity (I.e. unique even with –concurrent-events > 1). Cached for speed.

Definition at line 36 of file AlgorithmIdentifier.h.

m_realSlot

size_t AlgorithmIdentifier::m_realSlot

The actual slot of the algorithm.

Definition at line 31 of file AlgorithmIdentifier.h.

m_slotToSaveInto

size_t AlgorithmIdentifier::m_slotToSaveInto

The slot which is used for the purposes of recording data on this algorithm's execution.

Note: might not be the actual slot of the alg

Definition at line 32 of file AlgorithmIdentifier.h.

m_store

std::string AlgorithmIdentifier::m_store

Name of the algorithm's store.

e.g. '0_StoreGateSvc_Impl' for the main store.

Definition at line 34 of file AlgorithmIdentifier.h.

m_viewID

int16_t AlgorithmIdentifier::m_viewID

If not within an event view, then the m_iewID = s_noView = -1.

Definition at line 35 of file AlgorithmIdentifier.h.

s_noView

constexpr int16_t AlgorithmIdentifier::s_noView = -1

staticconstexpr

Constant value used to express an Algorithm which is not running in a View.
