In the above example we just read/write a string. If you have more than one element to write out, you must precede it with a map or array header. You must read the entire map/array when deserializing. For example:public class MySpecialObjectFormatter : IMessagePackFormatter<MySpecialObject...

若要删除std::vector中的element,正规的方式该用find() generic algorithm,若find()找到了,会传回该iterator,若找不到,将传回vector.end()。这种写法远比用for loop干净很多。 1 /* 2 (C) OOMusou 2006http://oomusou.cnblogs.com 3 4 Filename : VectorFindAndErase.cpp 5 Compiler : Visual C++ 8.0...
CAutoVectorPtrElementTraits 要求 标头:atlcoll.h CAutoVectorPtrElementTraits::INARGTYPE 用于将元素添加到集合类对象的数据类型。 复制 typedef CAutoVectorPtr<T>& INARGTYPE; CAutoVectorPtrElementTraits::OUTARGTYPE 用于从集合类对象中检索元素的数据类型。
