Detailed Description

template<class T>
class flow::Vector< T >

Envelop over std::vector, use enhanced iterators.

Differences compared to std::vector.

Implement only subset of std::vector methods.
iterator Iter - which is nothing else then T *. This we use since it can be initializeted to NULL as universal "non valid value". for iterators one has to comapre to std::vector.end(), but the container is not always at hand. This should be used in complex mesh structures to save space.
iterator FullIter - this is standard iterator which contains also reference to the containre it points to. Then it has more save "non valid value" method. Can be constructer from Iter and a container. You can get the index of this iterator. This is meant to be use as local variable. Using this instead of standard iterators It provides function to get index of an iterator
Provides method to get index of a pointer i.e. Iter.
add_item can be used to add a new element and get reference to it so that it can be initialized Useful even for T be class since when creating a new element the default constructor is called which can not fill it with values.

Developer note:

It appears very dangerous to combine reallocating std::vectors with iterators implemented as pointers. Indeed, when vector array is reallocated old pointers become invalid. One possibility is to strictly distinguish crating of the array and later creating references into it. Another is to implement iterators by indexes which means also to use only FullIterators.

Definition at line 226 of file sys_vector.hh.

template<class T >

typedef T flow::Vector< T >::ElementType

We have to export template type for FullIteraror.

Definition at line 220 of file sys_vector.hh.

template<class T >

typedef FullIterator<Vector<T> > flow::Vector< T >::FullIter

Type of FullIterator that should be used to iterate through this container.

Definition at line 228 of file sys_vector.hh.

template<class T >

typedef T* flow::Vector< T >::Iter

Default iterator for this class.

Definition at line 222 of file sys_vector.hh.

template<class T >

typedef std::vector<T>::iterator flow::Vector< T >::iterator

For compatibility with std::algorithms we provide also standard iterators. Theoretically it should work also with Iter. Test that if you need it.

Constructor & Destructor Documentation

template<class T >

flow::Vector< T >::Vector ( unsigned int size = 0 )

inline

Construct with reserve the space. Includes default constructor.

Definition at line 232 of file sys_vector.hh.

template<class T >

virtual flow::Vector< T >::~Vector ( )

inlinevirtual

Since storage is direct member it is deallocated by its own destructor.

Definition at line 310 of file sys_vector.hh.

Member Function Documentation

template<class T >

FullIter flow::Vector< T >::add_item ( )

inline

Add a new element into the container. Return iterator to it. Provides a way to add new element to the container and get an iterator to set its values. This way we need not copy a new element.

Definition at line 240 of file sys_vector.hh.

template<class T >

FullIter flow::Vector< T >::begin ( )

inline

Returns FullFullIterer of the first element.

Definition at line 257 of file sys_vector.hh.

Here is the caller graph for this function:

template<class T >

FullIter flow::Vector< T >::end ( )

inline

Returns FullFullIterer of the fictions past the end element.

Definition at line 261 of file sys_vector.hh.

template<class T >

FullIter flow::Vector< T >::full_iter ( Iter it )

inline

Alternative way to make FullIterer form Iter. This way you need not write the full FullIter type to call the constructor. Then the result can be assigned to suitable local FullIter variable.

Definition at line 306 of file sys_vector.hh.

template<class T >

unsigned int flow::Vector< T >::index ( Iter pointer ) const

inline

For given pointer returns the index of the element in the Vector. The first element has zero index.

Definition at line 249 of file sys_vector.hh.

template<class T >

FullIter flow::Vector< T >::operator() ( unsigned int idx )

inline

Gets iterator of the element specified by index.

Definition at line 289 of file sys_vector.hh.

template<class T >

T& flow::Vector< T >::operator[] ( unsigned int idx )

inline

Gets reference to the element specified by index.

Definition at line 274 of file sys_vector.hh.

template<class T >

const T& flow::Vector< T >::operator[] ( unsigned int idx ) const

inline

Gets reference to the element specified by index.

Definition at line 281 of file sys_vector.hh.

template<class T >

void flow::Vector< T >::reserve ( unsigned int size )

inline

Reallocates the container space.

Definition at line 297 of file sys_vector.hh.

Here is the caller graph for this function:

template<class T >

void flow::Vector< T >::resize ( const unsigned int size )

inline

Returns size of the container. This is independent of the allocated space.

Definition at line 269 of file sys_vector.hh.

template<class T >

unsigned int flow::Vector< T >::size ( ) const

inline

Returns size of the container. This is independent of the allocated space.
