Here is the call graph for this function:

template<typename VarType >

std::pair<VarType, VarType> Euclid::Histogram::Binning::Sqrt< VarType >::getBinEdges ( size_t  i ) const

inlinefinalvirtual

Get the two edges corresponding to the bin i

Parameters

i	The bin index

Returns

The two bin edges

Here is the call graph for this function:

template<typename VarType >

ssize_t Euclid::Histogram::Binning::Sqrt< VarType >::getBinIndex ( VarType  value ) const

inlinefinalvirtual

Get the bin index corresponding to the given value

Parameters

value

The value to map to a bin

Returns

The bin index. If value is outside of the bounds, a negative number or a value bigger or equal to m_nbins can be used to mark the fact

template<typename VarType >

VarType Euclid::Histogram::Binning::Sqrt< VarType >::getEdge ( size_t  e ) const

inlinefinalvirtual

Get the edge value e. Note that there are always one more edge than bins: i.e. the bin 0 has the edges (0, 1), the bin 1 the edges (1, 2), etc...
