Detailed Description

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

This is the highest level in the hierarchical cache structure. This class is used by DVInterface. The internal structure is a list of DVSeriesCache.

void DVStudyCache::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)

OFBool DVStudyCache::empty ( void  ) const

inline

checks whether study cache is empty

Returns

OFTrue if cache is empty, OFFalse otherwise

References OFList< T >::empty().

Uint32 DVStudyCache::getCount ( ) const

inline

gets number of cache entries

Returns

number of cache entries

References OFList< T >::size().
