Detailed Description

template<typename Int, typename BasInt, typename RedDbl>
class LatticeTester::ParamReader< Int, BasInt, RedDbl >

Utility class that can be used to read different kind of data from a file.

This class has to be initialized with a fileName to be used. After the object is initialized, it is then necessary to read the entire file with getLines. This will make a vector containing all the lines of the file, removing those with a # at the start. There then are many methods allowing the conversion of string tokens to various data types by specifying a line and a token number. In every line, a token is a string delimited by any of these caracters: (blank), ?, !, ,, \t, and \n. For example, ReadString(string, 2, 3) will put the 4th token (numerotation starts at 0) of the 3rd line in string. The user of this class has to be aware of the format of the file that will be read.

Remarks: This class should have proper error management in the GetToken method because the program curently simply crashes without explanation if this class is misued.
