Custom allocator in std::vector

c++stlc++11allocator

提问by Cartesius00

Is it possible to use custom allocator for std::vectorinternal allocations? If yes, how?

是否可以使用自定义分配器进行std::vector内部分配?如果是,如何?

采纳答案by bitmask

You basically have to implement your allocator type to conform to the Allocator concept.

您基本上必须实现您的分配器类型以符合分配器概念

The linked page lists all requirements of that type, but the core functionality is implemented in the allocatemember function.

链接页面列出了该类型的所有要求,但核心功能在allocate成员函数中实现。
