Detailed Description

template<typename TBase, typename TString>
class qmu::QmuParserToken< TBase, TString >

Encapsulation of the data for a single formula token.

Formula token implementation. Part of the Math Parser Package. Formula tokens can be either one of the following:

value
variable
function with numerical arguments
functions with a string as argument
prefix operators
infix operators
binary operator
