 Member functions
mask_array::mask_array
 
 (1)
 
private:
mask_array();
 
 (until C++11) 
mask_array();
public:
mask_array() = delete;
 
 (since C++11) 
mask_array() = delete;
public:
mask_array( const mask_array& other );
 (2) 
 
mask_array( const mask_array& other );
1) The default constructor is declared private and not defined(until C++11)explicitly defined as deleted(since C++11): 
mask_array is not DefaultConstructible.2) Constructs a 
mask_array from another mask_array other.[edit] Parameters
 other
 -
 
mask_array to initialize with
