template class mrpt::containers::vector_with_small_size_optimization

Overview

Container that transparently and dynamically switches between a std::array and std::vector.

Used to avoid heap allocations with small vectors.

Methods

reference at(size_type n)

Like [], but throws an exception if accessing out of bounds.

(Note in MRPT 2.3.3)

const_reference at(size_type n) const

Like [], but throws an exception if accessing out of bounds.

(Note in MRPT 2.3.3)

void push_back(const VAL& val)

Grows the container by one and writes the value in the new final position.
