Detailed Description

template<class Generator>
class RWTRand< Generator >

Class RWTRand<Generator> is the abstract base class for the random number generator classes. The classes derived from RWTRand<Generator> generate random numbers from specific probability distributions. Each of these derived classes generates a random number from a uniform distribution on the interval [0, 1], and from this deviate derives a random number generator from the appropriate probability distribution. The template parameter Generator is a function object that provides this uniform [0, 1] deviate. Specifically, Generator is presumed to be an object that overloads the function call operator to return a uniform random number of type double between 0 and 1.

The class Generator must have the following semantics, where gen is of type Generator:

Default Constructor:	Generator gen;
Function Call Operator:	double x = gen(); // 0 <= x <= 1 or 0 < x < 1
