## Detailed Description

template<class T>
class DSRListOfItems< T >

Template class to store and access items in a list structure.

For instances of this class T needs to have at least a default constructor, assignment and comparison operator.

References OFVector< T >::begin(), OFVector< T >::end(), and ItemList.

## addOnlyNewItem()

template<class T>

void DSRListOfItems< T >::addOnlyNewItem | ( | const T & | item | ) |

inline

Parameters

  item | item to be added

References isElement(), and ItemList.

## getItem() [1/2]

template<class T>

const T & DSRListOfItems< T >::getItem | ( | const size_t | idx | ) | const

inline

get reference to the specified item

Parameters

  idx | index of the item to be returned (starting from 1)

Returns
  reference to the specified item if successful, EmptyItem otherwise

References gotoItemPos(), and ItemList.

## getItem() [2/2]

template<class T>

OFCondition DSRListOfItems< T >::getItem | ( | const size_t | idx,
|  | T & | item ) const

inline

get copy of the specified item

Parameters

  idx | index of the item to be returned (starting from 1)
  item | reference to a variable where the result should be stored. (not changed/cleared if an error occurs!)

Returns
  status, EC_Normal if successful, an error code otherwise

References EC_IllegalParameter, EC_Normal, gotoItemPos(), and ItemList.

## getItems()

template<class T>

OFCondition DSRListOfItems< T >::getItems | ( | OFVector< T > & | items | ) | const

inline

get copy of all items (as a vector)

Parameters

  items | reference to a variable where the result should be stored. (always cleared before items are added)

Returns
  status, EC_Normal if successful, an error code otherwise

References OFVector< T >::clear(), EC_Normal, ItemList, OFVector< T >::push_back(), and OFVector< T >::reserve().
