Detailed Description

template<typename T, std::size_t N, bool value_init = true>
class MooseUtils::SemidynamicVector< T, N, value_init >

Utility class template for a semidynamic vector with a maximum size N and a chosen dynamic size.

This container avoids heap allocation and is meant as a replacement for small local std::vector variables. By default this class uses value initialization. This can be disabled using the third template parameter if uninitialized storage is acceptable,
