hitfit::Defaults_Textrep::Defaults_Textrep

(

string

file

)

Constructor, construct a Defaults_Textrep instance from an ASCII text-file and command line arguments.

Parameters:

file	The name of the input ASCII file to read. See the header file for a description of the format for this and the argument list. Pass an empty string to skip reading a file.

Constructor, construct a Defaults_Textrep instance from an ASCII text-file.

Parameters:

file	The name of the input ASCII file to read. See the header file for a description of the format for this and the argument list. Pass an empty string to skip reading a file.
argc	The length of the argument list.
argv	The argument list.
