Public Member Functions
Construction, conversion, and destruction

	~ArrayView_ ()
	The destructor just disconnects the array view handle from its data; see ArrayViewConst_<T,X>::disconnect() for more information. More...

Assignment
Assignment is permitted only if the source and destination are the same size. The semantics here are different than for a resizeable Array_ object: here the meaning is elementwise assignment rather than destruction followed by copy construction. That is, if our elements are of type T, and the source elements are of type T2, we will use the operator of T that best matches the signature T::operator=(const T2&) to perform the assignments. When the source also has type T, this is just T's copy assignment operator. We never perform any element destruction or construction here.
ArrayView_ &	operator= (const ArrayView_ &src)
	Copy assignment; source must be the same size as this array. More...

template<class T2 , class X2 >
ArrayView_ &	operator= (const ArrayViewConst_< T2, X2 > &src)
	Assignment from any other array object is allowed as long as the number of elements matches and the types are assignment compatible. More...

template<class T2 , class X2 >
ArrayView_ &	operator= (const Array_< T2, X2 > &src)
	Assignment from any other array object is allowed as long as the number of elements matches and the types are assignment compatible. More...

template<class T2 , class A2 >
ArrayView_ &	operator= (const std::vector< T2, A2 > &src)
	Assignment from any std::vector object is allowed as long as the number of elements matches and the types are assignment compatible. More...

ArrayView_ &	operator= (const T &fillValue)
	Fill assignment – all elements are set to fillValue. More...

ArrayView_ &	fill (const T &fillValue)
	Assign the supplied fill value to each element of this array, using T's copy assignment operator for each element. More...

void	assign (size_type n, const T &fillValue)
	This is the same as fill() but has the usual std::vector signature for compatibility; it will only work if the given number of elements is the same as this array's (fixed) size. More...

template<class T2 >
void	assign (const T2 first, const T2 last1)
	Assign to this array to make it a copy of the elements in range [first,last1) given by ordinary pointers, provided that the range is the same size as the array. More...

template<class Iter >
void	assign (const Iter &first, const Iter &last1)
	Assign to this array to make it a copy of the elements in range [first,last1) given by non-pointer iterators (the pointer case is handled with a specialized assign() variant). More...

Element access
These methods provide read and write access to individual elements that are currently present in the array; the ArrayViewConst_<T,X> base class provides the read-only (const) methods.

	Select an element by its index, returning a const reference. More...

T &	operator[] (index_type i)

Iterators
These methods deal in iterators, which are STL generalized pointers. For this class, iterators are just ordinary pointers to T, and you may depend on that. By necessity, reverse iterators can't be just pointers; however, they contain an ordinary iterator (i.e. a pointer) that can be obtained by calling the reverse iterator's base() method.

Template Parameters

T	The type of object to be stored in this container.
X	The type to be used for indexing this container, with default unsigned (not size_t). Any integral type may be used, as well as user types that satisfy the requirements discussed with class ArrayIndexTraits.

ArrayView_& SimTK::ArrayView_< T, X >::operator= ( const T & fillValue )

inline

Fill assignment – all elements are set to fillValue.

See Also: fill()

template<class T, class X = unsigned>

ArrayView_& SimTK::ArrayView_< T, X >::fill ( const T & fillValue )

inline

Assign the supplied fill value to each element of this array, using T's copy assignment operator for each element.

Note that this also serves to allow fill from an object whose type T2 is different from T, as long as there is a constructor T(T2) that works since that can be invoked (implicitly or explicitly) to convert the T2 object to type T prior to the call.

template<class T, class X = unsigned>

void SimTK::ArrayView_< T, X >::assign	(	size_type	n,
		const T &	fillValue
	)

inline

This is the same as fill() but has the usual std::vector signature for compatibility; it will only work if the given number of elements is the same as this array's (fixed) size.

template<class T, class X = unsigned>

template<class T2 >

void SimTK::ArrayView_< T, X >::assign	(	const T2 *	first,
		const T2 *	last1
	)

inline

Assign to this array to make it a copy of the elements in range [first,last1) given by ordinary pointers, provided that the range is the same size as the array.

It is not allowed for the source range to include any of the elements currently in the array. The source elements can be of a type T2 that may be the same or different than this array's element type T as long as there is a T=T2 assignment operator that works. Note that although the source arguments are pointers, those may be iterators for some container depending on implementation details of the container. Specifically, any ArrayViewConst_, ArrayView_, or Array_ iterator is an ordinary pointer.

Parameters

[in]	first	A pointer to the first element to be copied.
[in]	last1	A pointer to the element one past the last element to be copied.

Precondition: last1-first == size()

Complexity:: The T=T2 assignment operator will be called exactly size() times.

template<class T, class X = unsigned>

template<class Iter >

void SimTK::ArrayView_< T, X >::assign	(	const Iter &	first,
		const Iter &	last1
	)

inline

Assign to this array to make it a copy of the elements in range [first,last1) given by non-pointer iterators (the pointer case is handled with a specialized assign() variant).

It is not allowed for this range to include any of the elements currently in the array. The source elements can be of a type T2 that may be the same or different than this array's element type T as long as there is a T=T2 operator that works.

The source must have the same number of elements as the current (fixed) size of this ArrayView. For input_iterators we'll be happy if we get enough elements and won't insist that the input stream is empty after that. For forward_ and bidirectional_iterators we'll copy the elements and complain at the end if there are too few or too many. For random_access_iterators we'll check in advance since we can do that fast.

Parameters

[in]	first	An iterator pointing to the first element to be copied.
[in]	last1	An iterator pointing to the element one past the last element to be copied.

Remarks: This variant of assign() will not be called when the iterators are forward iterators from ArrayViewConst_, ArrayView_, or Array_ objects since those are ordinary pointers.

Precondition: last1 is reachable from first; distance(first,last1)==size()

Complexity:: The T=T2 assignment operator will be called exactly size() times.

const T& SimTK::ArrayView_< T, X >::operator[] ( index_type i ) const

inline

[in]	length	The length of the subarray to be produced.

Returns: A new ArrayView_<T,X> object referencing the original data.

Note: If length==0 the returned array will be in a default-constructed, all-zero and null state with no connection to the original data.

This method is from the proposed C++0x standard; there is also an overloaded begin() from the original standard that returns a const pointer.

template<class T, class X = unsigned>

const T* SimTK::ArrayView_< T, X >::begin ( ) const

inline

The const version of begin() is the same as cbegin().

template<class T, class X = unsigned>

T* SimTK::ArrayView_< T, X >::begin ( )

inline

Return a writable pointer to the first element of this array if any, otherwise end().

If the array is empty, this may return null (0) but does not have to – the only thing you can be sure of is that begin() == end() for an empty array.

template<class T, class X = unsigned>

const T* SimTK::ArrayView_< T, X >::cend ( ) const

inline

Return a const pointer to what would be the element just after the last one in the array; this may be null (0) if there are no elements but doesn't have to be.

This method is from the proposed C++0x standard; there is also an overloaded end() from the original standard that returns a const pointer.

template<class T, class X = unsigned>

const T* SimTK::ArrayView_< T, X >::end ( ) const

inline

The const version of end() is the same as cend().

template<class T, class X = unsigned>

T* SimTK::ArrayView_< T, X >::end ( )

inline

Return a writable pointer to what would be the element just after the last one in this array.

If the array is empty, this may return null (0) but does not have to – the only thing you can be sure of is that begin()==end() for an empty array.

template<class T, class X = unsigned>

const_reverse_iterator SimTK::ArrayView_< T, X >::crbegin ( ) const

inline

Return a const reverse iterator pointing to the last element in the array or crend() if the array is empty.

template<class T, class X = unsigned>

const_reverse_iterator SimTK::ArrayView_< T, X >::rbegin ( ) const

inline

The const version of rbegin() is the same as crbegin().

template<class T, class X = unsigned>

reverse_iterator SimTK::ArrayView_< T, X >::rbegin ( )

inline

Return a writable reverse iterator pointing to the last element in the array or rend() if the array is empty.

template<class T, class X = unsigned>

const_reverse_iterator SimTK::ArrayView_< T, X >::crend ( ) const

inline

Return the past-the-end reverse iterator that tests equal to a reverse iterator that has been incremented past the front of the array.

You cannot dereference this iterator.

template<class T, class X = unsigned>

const_reverse_iterator SimTK::ArrayView_< T, X >::rend ( ) const

inline

The const version of rend() is the same as crend().

template<class T, class X = unsigned>

reverse_iterator SimTK::ArrayView_< T, X >::rend ( )

inline

Return a writable past-the-end reverse iterator that tests equal to a reverse iterator that has been incremented past the front of the array.

You cannot dereference this iterator.

template<class T, class X = unsigned>

const T* SimTK::ArrayView_< T, X >::cdata ( ) const

inline

Return a const pointer to the first element of the array, or possibly (but not necessarily) null (0) if the array is empty.

Note: cdata() does not appear to be in the C++0x standard although it would seem obvious in view of the cbegin() and cend() methods that had to be added. The C++0x overloaded const data() method is also available.

template<class T, class X = unsigned>

const T* SimTK::ArrayView_< T, X >::data ( ) const

inline

The const version of the data() method is identical to cdata().

Note: This method is from the proposed C++0x std::vector.

template<class T, class X = unsigned>

T* SimTK::ArrayView_< T, X >::data ( )

inline

Return a writable pointer to the first allocated element of the array, or a null pointer if no space is associated with the array.

Note: This method is from the proposed C++0x std::vector.

template<class T, class X = unsigned>

size_type SimTK::ArrayView_< T, X >::size ( ) const

inline

template<class T, class X = unsigned>

size_type SimTK::ArrayView_< T, X >::max_size ( ) const

template<class T, class X = unsigned>

bool SimTK::ArrayView_< T, X >::empty ( ) const

template<class T, class X = unsigned>

size_type SimTK::ArrayView_< T, X >::capacity ( ) const

template<class T , class X >

std::istream & operator>>	(	std::istream &	in,
		ArrayView_< T, X > &	out
	)

If there are no delimiters then we will read size() values and then stop. Otherwise, there must be exactly size() values within the brackets. Each element is read in with its own operator ">>" so this won't work if no such operator is defined for type T.
