Detailed Description

template<class T, int n>
class Dune::Functions::ReservedDeque< T, n >

A double-ended queue (deque) class with statically reserved memory.

ReservedDeque is something between std::array and std::deque. You have a double ended queue which can be extended and shrunk using methods like push_back and pop_back at the end, or via push_front and pop_front, but reserved memory is predefined.

This implies that the deque cannot grow bigger than the predefined maximum size.

Template Parameters

T	The data type ReservedDeque stores
n	The maximum number of objects the ReservedDeque can store
