Member Function Documentation

ScoreboardSlot * Scoreboard::findOurScoreboardSlot ( drizzled::Session session)

Finds the ScoreboardSlot for a given session. This function differs from findAndResetScoreboardSlot() as it returns the actual pointer rather then a copy. Its possible that values could be changed in the underlying status variables, callers should beware.

Definition at line 190 of file scoreboard.cc.

ScoreboardSlot * Scoreboard::findScoreboardSlotToLog ( drizzled::Session session)

Locates a ScoreboardSlot that is not in use, marks the slot as being used and returns a pointer to it. The caller can update individual statistics via the pointer without having to lock or worry about concurrent updates.

Parameters:
Pointerto the session
Returns:
Pointer to the ScoreboardSlot whose individual statistics can be updated
