Detailed Description

template<typename T>
class Fifo< T >

Simple FIFO implementation backed by a circular buffer.

This class provides the same basic functionallity as the circular buffer with the folling differences:

• Writes are checked to ensure that overflows can't happen.
• Unserialization ensures that the data in the checkpoint fits in the buffer.
