Luboš Luňák 0cc8da4c09 remove the o3tl::lru_map "unlimited" hack 
It didn't quite make sense before that maxsize == 0 meant no cleanup,
and now with items optionally being count as having size more than 1
it makes even less sense to limit the size to max_size() of the
containers. This comes from 16a338e173,
so instead make that special caller pass a large size, which in
practice is the same.

LibreOffice Template Library

Very basic template functionality, a bit like boost or STL, but specific to LibreOffice.

o3tl stands for "OOo [o3, get it?] template library", in which OOo stands for OpenOffice.org, predecessor of LibreOffice.

From https://blog.thebehrens.net/2006/01/15/update-cow_wrapper-is-available-now/ The scope for o3tl is admittedly kind of ambitious, as it should contain "...very basic (template) functionality, comparable to what's provided by boost or stl, but specific to OOo (what comes to mind are e.g. STL adapters for our own data types and UNO, and stuff that could in principle be upstreamed to boost, but isn't as of now)."

Class Overview

  • [git:include/o3tl/cow_wrapper.hxx]

    A copy-on-write wrapper.

  • [git:include/o3tl/lazy_update.hxx]

    This template collects data in input type, and updates the output type with the given update functor, but only if the output is requested. Useful if updating is expensive, or input changes frequently, but output is only comparatively seldom used.

  • [git:include/o3tl/vector_pool.hxx]

    Simple vector-based memory pool allocator.

  • [git:include/o3tl/functional.hxx]

    Some more templates, leftovers in spirit of STLport's old functional header that are not part of the C++ standard (STLport has been replaced by direct use of the C++ STL in LibreOffice).
