Detailed Description

Template implementation of MMappedVector<T>.

Provides the out-of-line definitions of all MMappedVector<T> methods declared in MMappedVector.h. This file must be included by any translation unit that instantiates MMappedVector<T> for a specific T.

Implemented methods:

• MMappedVector(): open/create the backing file and map it.
• ~MMappedVector(): sync and unmap.
• operator[](k) const: read element k.
• operator[](k): write element k.
• add(): append one element, growing the file if necessary.
• sync(): flush dirty pages with msync().

Internal helpers:

• mmap(): map (or remap) length bytes.
• grow(): double the capacity and remap.
