正在从concurrent_unordered_map中删除itens列表

concurrent_unordered_map是一个并发哈希表,它是C++标准库中的一部分,用于在多线程环境下进行并发访问和修改。它提供了一种线程安全的方式来存储和访问键值对。

删除itens列表的过程可以通过以下步骤完成:

  1. 首先,获取对concurrent_unordered_map的互斥锁,以确保在删除操作期间没有其他线程对该容器进行修改。
  2. 然后,使用迭代器遍历concurrent_unordered_map中的所有元素,找到需要删除的元素。
  3. 一旦找到需要删除的元素,使用erase()函数将其从concurrent_unordered_map中删除。
  4. 最后,释放互斥锁,允许其他线程对concurrent_unordered_map进行修改。

concurrent_unordered_map的优势在于它提供了高效的并发访问和修改能力,可以在多线程环境下安全地进行操作。它适用于需要在并发环境下进行键值对存储和访问的场景,例如多线程的服务器应用程序、并行计算等。

    java.util.stream public interface Collector<T, A, R> A mutable reduction operation that accumulates input elements into a mutable result container, optionally transforming the accumulated result into a final representation after all input elements have been processed. Reduction operations can be performed either sequentially or in parallel. Examples of mutable reduction operations include: accumulating elements into a Collection; concatenating strings using a StringBuilder; computing summary information about elements such as sum, min, max, or average; computing "pivot table" summaries such as "maximum valued transaction by seller", etc. The class Collectors provides implementations of many common mutable reductions. A Collector is specified by four functions that work together to accumulate entries into a mutable result container, and optionally perform a final transform on the result. They are: creation of a new result container (supplier()) incorporating a new data element into a result container (accumulator()) combining two result containers into one (combiner()) performing an optional final transform on the container (finisher()) Collectors also have a set of characteristics, such as Collector.Characteristics.CONCURRENT, that provide hints that can be used by a reduction implementation to provide better performance. A sequential implementation of a reduction using a collector would create a single result container using the supplier function, and invoke the accumulator function once for each input element. A parallel implementation would partition the input, create a result container for each partition, accumulate the contents of each partition into a subresult for that partition, and then use the combiner function to merge the subresults into a combined result. To ensure that sequential and parallel executions produce equivalent results, the collector functions must satisfy an identity and an associativity constraints. The identity constraint says that for any partially accumulated result, combi
