all_of() [1/2]

template<typename T , class Predicate >

bool dtk::all_of	(	const Dtk_tab< T > &	tab,
		Predicate	Pred
	)

Test condition on all elements in range, and returns true if pred returns true for all the elements in the range [first,last] or if the range is empty, and false otherwise.

Parameters

first	Input iterator to the initial position in a sequence
last	Input iterator to the final position in a sequence
Pred	Unary function that accepts an element in the range as argument and returns a value convertible to bool.

Remarks

Note that invalid parameters cause undefined behavior.

Specialized version for Dtk_tab.

     {
          for(Dtk_Size_t i = 0; i < tab.size(); ++i)
               if(!Pred(tab[i]))
                    return false;
          return true;
     }

all_of() [2/2]

template<class InputIterator , class Predicate >

bool dtk::all_of	(	InputIterator	first,
		InputIterator	last,
		Predicate	Pred
	)

Test condition on all elements in range, and returns true if pred returns true for all the elements in the range [first,last] or if the range is empty, and false otherwise.

Parameters

first	Input iterator to the initial position in a sequence
last	Input iterator to the final position in a sequence
Pred	Unary function that accepts an element in the range as argument and returns a value convertible to bool.

Remarks

Note that invalid parameters cause undefined behavior.

     {    // test if all elements satisfy _Pred
          for (; first != last; ++first)
               if (!Pred(*first))
                    return false;
          return true;
     }

any_of() [1/2]

template<typename T , class Predicate >

bool dtk::any_of	(	const Dtk_tab< T > &	tab,
		Predicate	Pred
	)

Test if any element in range fulfills condition, returns true if pred returns true for any of the elements in the range [first,last], and false otherwise or if the range is empty.

Parameters

first	Input iterator to the initial position in a sequence
last	Input iterator to the final position in a sequence
Pred	Unary function that accepts an element in the range as argument and returns a value convertible to bool.

Remarks

Note that invalid parameters cause undefined behavior.

Specialized version for Dtk_tab.

     {
          for(Dtk_Size_t i = 0; i < tab.size(); ++i)

                    return true;
          return false;
     }

any_of() [2/2]

template<class InputIterator , class Predicate >

bool dtk::any_of	(	InputIterator	first,
		InputIterator	last,
		Predicate	Pred
	)

Test if any element in range fulfills condition, returns true if pred returns true for any of the elements in the range [first,last], and false otherwise or if the range is empty.

Parameters

first	Input iterator to the initial position in a sequence
last	Input iterator to the final position in a sequence
Pred	Unary function that accepts an element in the range as argument and returns a value convertible to bool.

Remarks

          return false;
     }

none_of() [1/2]

template<typename T , class Predicate >

bool dtk::none_of	(	const Dtk_tab< T > &	tab,
		Predicate	Pred
	)

Test if no elements fulfill condition, returns true if pred returns false for all the elements in the range [first,last] or if the range is empty, and false otherwise.

Parameters

first	Input iterator to the initial position in a sequence
last	Input iterator to the final position in a sequence
Pred	Unary function that accepts an element in the range as argument and returns a value convertible to bool.

Remarks
