Member Function Documentation

operator()() [1/2]

T operator() ( )

inline

Generate a random number.

Definition at line 264 of file Random.H.

operator()() [2/2]

T operator() ( const U &  ) const

inline

Ignore parameter and generate a random number, which allows it to be used as a replacement for general unary operators.
