Detailed Description

A class to handle a series cache (list of items).

This is the middle level in the hierarchical cache structure. This class is used by DVStudyCache. The internal structure is a list of DVInstanceCache.

Member Function Documentation

addItem()

void DVSeriesCache::addItem ( const OFString &  uid, const DVIFhierarchyStatus  status = DVIF_objectIsNew  )

inline

adds a new item to the cache list.

sets internal cursor to new position.

Parameters

uid	unique identifier
status	review status (optional)

empty()

OFBool DVSeriesCache::empty ( void  ) const

inline

checks whether instance cache is empty

Returns

OFTrue if cache is empty, OFFalse otherwise

getCount()

Uint32 DVSeriesCache::getCount ( ) const

inline

gets number of cache entries

Returns

number of cache entries

getItem()

ItemStruct* DVSeriesCache::getItem ( ) const

inline

gets reference to current (selected) series

Returns

pointer to ItemStruct if successful, NULL otherwise

getStatus()

DVIFhierarchyStatus DVSeriesCache::getStatus ( ) const

inline

gets review status of the current (selected) series

Returns

hierarchical status code if successful, 'isNew' otherwise

References DVSeriesCache::ItemStruct::Status.

getType()

DVPSInstanceType DVSeriesCache::getType ( ) const

inline

gets type of all instances in the series

Returns

type of all instances

References DVSeriesCache::ItemStruct::Type.

gotoFirst()

OFBool DVSeriesCache::gotoFirst ( )

inline

sets internal cursor to first position in cache list

Returns

OFTrue if successful, OFFalse if list is empty

gotoItem()

OFBool DVSeriesCache::gotoItem ( Uint32  idx )

inline

sets internal cursor to specified position in cache list

Parameters

idx	index position in cache list (starting with 0)

Returns

OFTrue if successful, OFFalse if 'idx' is invalid

gotoNext()

OFBool DVSeriesCache::gotoNext ( )

inline

sets internal cursor to next position in cache list

Returns

OFTrue if successful, OFFalse if new position is invalid

isElem()

OFBool DVSeriesCache::isElem ( const OFString &  uid )

inline

checks whether an item with the specified UID exists in the cache list

Parameters

uid	UID which should be checked

Returns

OFTrue if such an item exists, OFFalse otherwise

reset()

OFBool DVSeriesCache::reset ( )

inline

sets internal cursor to last visited position in cache list

Returns

OFTrue if successful, OFFalse if last visited position was invalid or the last one in the list

updateStatus()

DVIFhierarchyStatus DVSeriesCache::updateStatus ( )

inline

updates hierarchical/review status for all list items.

Returns

resulting review status (summary of all items)
