m.value_comp()(*it_l,*it_r)==true(least to greatest if using the default comparison). Everywhere the standard library uses theComparerequirements, uniqueness is determined by using the equivalence relation. In imprecise terms, two objectsaandbare considered equivalent (not unique) if neither co...
inline是编译时展开,必须有实体; static属于class自己的,也必须有实体; virtual函数基于vtable(内存空间),constructor函数如果是virtual的,调用时也需要根据vtable寻找,但是constructor是virtual的情况下是找不到的,因为constructor自己本身都不存在了,创建不到class的实例,没有实例,class的成员(除了public static/protected ...

If you are using Hazelcast IMDG and C++ Client on the same computer, generally the default configuration should be fine. This is great for trying out the client. However, if you run the client on a different computer than any of the cluster members, you may need to do some simple ...
