What allocation algorithm you use is up to you, it could be something simple like +10 characters, I have sometimes used *1.6 of the current size which is a fairly efficient growth algorithm for its complexity. Then when you allocate extra data you can expand the buffer by more than a single character which means you wont have to allocate every time you store an extra character. That way the buffer size can be larger than the string size. Strings private data should contain 3 members, size, capacity and pointer where size is the actual size of the string and capacity is the current size of the buffer. What would be better is to have a array that is at least big enough to store the string but may be bigger. Here is the crunch, if you store the data you have (size and pointer) that implies that the size is the exact size of the String, every time you store a new character you will need to reallocate, that will be very inefficient (but it would work). If there isn't then you must reallocate the Strings internal array. Here is the problem, as you say you have no idea how many characters you are going to get input so you can not allocate enough data in advance, that means that every-time you store a new character in the String the first thing you have to check is if there is enough data to store the character. Otherwise add it to the array in your string. Having got the character you need to check it to see if it meets your end condition that is if it is whatever character you are going to say delimits strings, for std::string that is any white space but you could make it anything you want. In your operator you need to read a fixed amount of data at a time, probably 1 char to prevent the function from accidentally reading data destined for a different String.

More.ĭefault serializer template to call stream operators only on types that support them. Serialization for that converts components data types to ignition::msgs. It is passed in as the third template parameter to components::Component. This will make them findable only via ADL, and is generally what you want. A Serializer class is used to serialize and deserialize a component. I strongly recommend making operator> and operator<< into inline friend functions define them right inside the body of your class.
