Detailed Description

template<class Generator>
class RWTRand< Generator >

Class RWTRand is the abstract base class for the random number generator classes. The classes derived from RWTRand 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
