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:
    Source code (C++)
    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:
    Source code (C++)
    // 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:
    Source code (C++)
    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:
    Source code (C++)
    // 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:
    Notice
    If an element already exists in the initial set, it will not be added.
    Source code (C++)
    // 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());
