virtual void Fast1DCentEstimator::PostEvent ( )

inlinevirtual

Fills the summed observable into the histogram

Reimplemented from FastCentEstimator.

virtual void Fast1DCentEstimator::Setup ( TCollection *  l, TTree *  tree, UShort_t  , Bool_t  , Bool_t    )

inlinevirtual

Set-up this object. Defines the internal histogram and add to output

Parameters

l	Output list
tree	Tree to add branch to

Implements FastCentEstimator.

Reimplemented in ZNCentEstimator, RefMultEstimator, V0CentEstimator, and BCentEstimator.

Definition at line 212 of file FastCentEstimators.C.

Referenced by BCentEstimator::Setup(), V0CentEstimator::Setup(), RefMultEstimator::Setup(), and ZNCentEstimator::Setup().

virtual void Fast1DCentEstimator::Terminate ( TCollection *  out )

inlinevirtual

Called at the end of the processing. The member function produces a histogram like the defined observable histogram, but the bin content corresponds to the centrality corresponding to that bin. In that way, we can do a simple look-up in the output histogram to extract the centrality

Parameters

out	Output list to add information to.

Implements FastCentEstimator.

Reimplemented in BCentEstimator.
