Unigine::Set Class
Header: | #include <UnigineSet.h> |
A set is a container template in which each element must be unique as the value of the element identifies it. The values are stored in the ascending order.
To create a new set, you can use the default constructor or one of the following ways:
- Create a new set by using the constructor with an initializer list:
const Set<int> my_set{ 1, 6, 4, 3, 7 }; // check the result for (const auto &it : my_set) Log::message("%d ", it.key);
- Create a new set using a copy constructor:
// constructor that takes an initializer list const Set<String> initial{ "a", "e" }; // copy constructor const Set<String> copied(initial); // check the result for (const auto &it : copied) Log::message("%s ", it.key.get());
Also you can modify a set by using the append() and insert() class member functions. Check some of the usage examples:
- Create a new set and append elements to it one by one:
Set<int> my_set; my_set.append(1); my_set.append(10); my_set.append(4); // check the result for (const auto &it : my_set) Log::message("%d ", it.key);
- Create a new set and append another set to it:
// create a set using an initializer list const Set<int> my_set_0{ 1, 6, 4, 3, 7 }; // declare a new set Set<int> my_set_1; // append the "my_set_0" to it my_set_1.append(my_set_0); // check the result for (const auto &it : my_set) Log::message("%d ", it.key);
- Modify the existing set that already contains elements:
If an element already exists in the initial set, it will not be added.
// create sets using initializer lists Set<String> initial{ "a", "b", "c", "d", "e" }; Set<String> to_add{ "m", "n", "o" }; // append keys of the "to_add" set to the "initial" set initial.append(to_add); // insert a key into the "initial" set initial.insert("s"); // check the result for (const auto &it : initial) Log::message("%s ", it.key.get());
