Member Enumeration Documentation

anonymous enum

Various flags

Enumerator
kMaxNearDistance	The maximum distance to the given run when selecting in kNear mode. Currently this is set to a large number to allow selection of any entry. This should change
kInvalidField

Definition at line 79 of file AliOADBForward.h.

enum AliOADBForward::ERunSelectMode

Options for selecting the entries according to the run number given in the query.

Enumerator
kDefault
kExact	Select only entries from exactly the run given.
kNewest	Select the entry with the largest run number
kNear	Select entries from the run nearest (possibly constrained to be older or newer) to the run given in the query
kOlder	Select entries from runs that are older than the run given in the query. The oldest entry with the largest run number smaller than the given run is selected.
kNewer	Select entries from runs that are newer than the run given. Select the entries with the smallest run number which is larger than the given run.

AliOADBForward::Entry * AliOADBForward::Get	(	const TString &	table,

		UShort_t	sNN = 0,
		Short_t	fld = 0,
		Bool_t	mc = false,
		Bool_t	sat = false
	)		const

Query the table for an object. The strategy is as follows.

• First query with all fields
  • If this returns a single entry, return that.
  • If not, then ignore the run number (if given)
    • If this returns a single entry, return that
    • Otherwise, give up and return null

This allow us to specify default objects for a period, and for collision system, energy, and field setting.

Parameters

table	Table name
run	Run number
mode	Run selection mode
sys	Collision system (1: pp, 2: PbPb, 3: pPb)
sNN	Center of mass energy (GeV)
fld	L3 magnetic field (kG)
mc	For MC only
sat	For satellite interactions

Returns

Found entry, or null
