// DESCRIPTION
|
|
// -----------
|
|
//
|
|
// This class is used to emulate the VariableLengthPartition class in LHC++
|
|
// Histoograms. It is used to contain an arbitrary binnng scheme. Member
|
|
// functions provide information on the locations of the bin-edges, and the
|
|
// bin within which a user-provided G4double falls.

// PUBLIC MEMBER FUNCTIONS
|
|
// -----------------------
|
|
//
|
|
// VariableLengthPartition (double *ep_list, size_t ep_list_len,
|
|
// side *ep_conv, size_t ep_conv_len)
|
|
// Constructor defining:
|
|
// 1. ep_list is a pointer to a double array defining the bin edges;
|
|
// 2. ep_list_len is the number of values in ep_list;
|
|
// 3. ep_conv the convention of data-points exactly on a bin-edge (if the
|
|
// datapoint is associated with the bin to the left of the bin-edge
|
|
// then ep_conv[i]==LEFT, otherwise ep_conv[i]==RIGHT);
|
|
// 4. ep_conv_len is the number of values in ep_conv_len.
|
|
//
|
|
// VariableLengthPartition ()
|
|
// Default constructor.
|
|
//
|
|
// ~VariableLengthPartition ()
|
|
// Destructor.
|
|
//
|
|
// const long get_elem_bin (double *data_point)
|
|
// Returns the bin number within which the value *data_point falls. If
|
|
// *data_point falls below the lower edge of the lowest bin, then
|
|
// BIN_UNDERFLOW is returned; if *data_point exceeds the upper edge of the
|
|
// highest bin then BIN_OVERFLOW is returned (see Histograms).
|
|
//
|
|
// double get_bin_position (size_t bin_id)
|
|
// Returns the lower-edge of the bin bin_id. If bin_id is equal to the
|
|
// number of bins, then the upper edge of the last bin is returned.
|
|
//
|
|
// size_t total_bins ()
|
|
// Returns the number of bins in the binning scheme.

// --------------
|
|
//
|
|
// 30 June 1999, P R Truscott, DERA UK
|
|
// Version number update 0.b.2 -> 0.b.3, but no functional change.
|
|
//
|

// 28 August 1999, F Lei, DERA UK
|
|
// Version number update 0.b.3 -> 0.b.4, but no functional change.

|
//
|
|
// 17 September 1999, F Lei & P R Truscott, DERA UK
|

|
|
//
|
|
// 09 March 2000, P R Truscott, DERA UK
|
|
// Update 0.b.3 -> 1.0, for compliance with ISO ANSI C++.
