clear Clear content (public member function ) 清空一个容器 emplace Construct and insert element (public member function ) 插入一个数值,emplace() 在插入元素时,是在容器的指定位置直接构造元素,而不是先单独生成,再将其复制(或移动)到容器中,所以速度相比于insert会快一些。但是如果在中间,仍要花费O(N)来...
void insert(iterator position, size_type n, const value_type& val) void insert(iterator position, const_iterator first, const_iterator last) Insert elements The vector is extended by inserting new elements before the element at the specified position, effectively increasing the container size by th...
To insert other attributes, specify custom parameters related to these attributes. Examples: create_time 1663637425 and location Hangzhou. Output If the operation is successful, the number of inserted keys is returned. If an existing field is updated, a value of 0 is returned. Otherwise, an ...

JIT identifies that a parameter or result represents a predicate value, it introduces a conversion node,VectorToMask(), in the intermediate representation. This conversion changes the type toTYP_MASK. For example, in theCompactAPI, the first parameter is a predicate, so we insert this conversion...
