Function Documentation

template<typename _RandomAccessIterator >

bool std::is_heap	(	_RandomAccessIterator	__first,
		_RandomAccessIterator	__last
	)		[inline]

Determines whether a range is a heap.

Parameters:

__first	Start of range.
__last	End of range.

Returns:

True if range is a heap, false otherwise.

Definition at line 566 of file stl_heap.h.

template<typename _RandomAccessIterator , typename _Compare >

bool std::is_heap	(	_RandomAccessIterator	__first,
		_RandomAccessIterator	__last,
		_Compare	__comp
	)		[inline]

Determines whether a range is a heap using comparison functor.

Parameters:

__first	Start of range.
__last	End of range.
__comp	Comparison functor to use.

Returns:

True if range is a heap, false otherwise.

Definition at line 579 of file stl_heap.h.

template<typename _RandomAccessIterator >

_RandomAccessIterator std::is_heap_until	(	_RandomAccessIterator	__first,
		_RandomAccessIterator	__last
	)		[inline]

Search the end of a heap.

Parameters:

__first	Start of range.
__last	End of range.

Returns:

An iterator pointing to the first element not in the heap.

This operation returns the last iterator i in [__first, __last) for which the range [__first, i) is a heap.

Definition at line 518 of file stl_heap.h.

template<typename _RandomAccessIterator , typename _Compare >

_RandomAccessIterator std::is_heap_until	(	_RandomAccessIterator	__first,
		_RandomAccessIterator	__last,
		_Compare	__comp
	)		[inline]

Search the end of a heap using comparison functor.

Parameters:

__first	Start of range.
__last	End of range.
__comp	Comparison functor to use.

Returns:

An iterator pointing to the first element not in the heap.

This operation returns the last iterator i in [__first, __last) for which the range [__first, i) is a heap. Comparisons are made using __comp.

template<typename _RandomAccessIterator >

void std::make_heap	(	_RandomAccessIterator	__first,
		_RandomAccessIterator	__last
	)

Construct a heap over a range.

Parameters:

__first	Start of heap.
__last	End of heap.

This operation makes the elements in [first,last) into a heap.

Definition at line 381 of file stl_heap.h.

template<typename _RandomAccessIterator , typename _Compare >

void std::make_heap	(	_RandomAccessIterator	__first,
		_RandomAccessIterator	__last,
		_Compare	__comp
	)

Construct a heap over a range using comparison functor.

Parameters:

__first	Start of heap.
__last	End of heap.
__comp	Comparison functor to use.

This operation makes the elements in [first,last) into a heap. Comparisons are made using __comp.

template<typename _RandomAccessIterator >

void std::pop_heap	(	_RandomAccessIterator	__first,
		_RandomAccessIterator	__last
	)		[inline]

Pop an element off a heap.

Parameters:

__first	Start of heap.
__last	End of heap.

Precondition:

[__first, __last) is a valid, non-empty range.

This operation pops the top of the heap. The elements first and __last-1 are swapped and [__first,last-1) is made into a heap.

Definition at line 282 of file stl_heap.h.

template<typename _RandomAccessIterator , typename _Compare >

void std::pop_heap	(	_RandomAccessIterator	__first,
		_RandomAccessIterator	__last,
		_Compare	__comp
	)		[inline]

Pop an element off a heap using comparison functor.

Parameters:

__first	Start of heap.
__last	End of heap.
__comp	Comparison functor to use.

This operation pops the top of the heap. The elements first and __last-1 are swapped and [__first,last-1) is made into a heap. Comparisons are made using comp.

template<typename _RandomAccessIterator >

void std::push_heap	(	_RandomAccessIterator	__first,
		_RandomAccessIterator	__last
	)		[inline]

Push an element onto a heap.

Parameters:

__first	Start of heap.
__last	End of heap + element.

This operation pushes the element at last-1 onto the valid heap over the range [first,last-1). After completion, [first,last) is a valid heap.

Definition at line 157 of file stl_heap.h.

template<typename _RandomAccessIterator , typename _Compare >

void std::push_heap	(	_RandomAccessIterator	__first,
		_RandomAccessIterator	__last,
		_Compare	__comp
	)		[inline]

Push an element onto a heap using comparison functor.

Parameters:

__first	Start of heap.
__last	End of heap + element.
__comp	Comparison functor.

This operation pushes the element at last-1 onto the valid heap over the range [__first,last-1). After completion, [first,last) is a valid heap. Compare operations are performed using comp.

template<typename _RandomAccessIterator >

void std::sort_heap	(	_RandomAccessIterator	__first,
		_RandomAccessIterator	__last
	)

Sort a heap.

Parameters:

__first	Start of heap.
__last	End of heap.

This operation sorts the valid heap in the range [first,last).

Definition at line 460 of file stl_heap.h.

template<typename _RandomAccessIterator , typename _Compare >

void std::sort_heap	(	_RandomAccessIterator	__first,
		_RandomAccessIterator	__last,
		_Compare	__comp
	)

Sort a heap using comparison functor.

Parameters:

__first	Start of heap.
__last	End of heap.
__comp	Comparison functor to use.

This operation sorts the valid heap in the range [first,last). Comparisons are made using __comp.
