Detailed Description

template<class T, class Alloc = std::allocator<T>>
class RTT::os::local_allocator< T, Alloc >

A simple local allocator which keeps a small pool which you can grow manually with grow(). It delegates allocation to the Alloc for each allocation request, also if the pool is empty. The pool works on a per-type basis globally (static !). The pool is thus _not_ per-object. A per-object allocator is not allowed by the standard. The pool is deallocated upon global destruction.

Parameters:
Tthe type to allocate memory for
Allocthe allocator to delegate allocation to.
