Detailed Description

template<class T>
class xsens::FifoQueueBasic< T >

A FIFO queue with limited length (cyclic).

The class is based on the STL queue class, but has a limited size. If more items are inserted than would fit, the oldest item is overwritten. The class can only handle non-pointer types.
