Compelling examples of custom C++ allocators? - Stack Overflow What are some really good reasons to ditch std::allocator in favor of a custom solution? Have you run across any situations where it was absolutely necessary for correctness, performance, scalabili
polymorphic_allocator: when and why should I use it? A polymorphic allocator solution on the other hand dictates that a polymorphic allocator must be used This precludes using std:: containers which use the default allocator, and might have implications for interfacing with legacy code
How are allocator in C++ implemented? - Stack Overflow The allocator "interface" (really just a set of requirements, enforced during template instantiation) is a wrapper around this process, allowing alternative memory provisioning approaches to be employed
c++ - using std::unique_ptr with allocators - Stack Overflow I was trying my hand with allocators this time amp; felt that there were many chances of leaking the resources So I thought what if I used std::unique_ptr to handle them I tried my hand with a s
c++ - What are the differences between Block, Stack and Scratch . . . A block allocator is presumably similar to a pool allocator, where the allocator returns chunks of specific (fixed) sizes (that are usually pre-allocated) - so good when you have lots of objects (with longer lifetime) with the same size A scratch allocator is probably an allocator that returns memory with a short lifetime (e g : one frame) for handling short, temporary allocations, and
c++ - what does (template) rebind lt; gt; do? - Stack Overflow Where "_Alloc" corresponds with the allocator template argument (and _Ty the contained type) I have trouble finding a good explanation of this "keyword" Best thing I've found so far is that it is part of the allocator interface Though even cppreference isn't very good in explaining this What does this template rebind<> do?
c++11 - How to use allocators in modern C++ - Stack Overflow The question is, how is one supposed to use allocators in new code? What is the "right" way now? From what I deduce in the documentation, construct is part of the allocator traits, rather than the allocator itself I am building a custom container, here it is a very simple version of the constructor, is this a good usage of the new design?
Modern approach to making std::vector allocate aligned memory The specified allocator type has to implement at least allocate, deallocate, and value_type In contrast to these answers, this implementation of such an allocator avoids platform-dependent aligned malloc calls
