Documentación del constructor y destructor

QGCache::QGCache	(	int	maxCost,
		uint	size,
		KeyType	kt,
		bool	caseSensitive,
		bool	copyKeys
	)		[protected]

Constructs a cache. The maximum cost of the cache is given by maxCost and the size by size. The key type is kt which may be StringKey, AsciiKey, IntKey or PtrKey. The case-sensitivity of lookups is set with caseSensitive. Keys are copied if copyKeys is TRUE.

QGCache::QGCache

(

const QGCache &

)

[protected]

Cannot copy a cache.

QGCache::~QGCache

(

)

[protected]

Removes all items from the cache and destroys it.

QPtrCollection::Item QGCache::find_other	(	const char *	key,
		bool	ref = TRUE
	)		const [protected]

Finds an item for key in the cache and adds a reference if ref is TRUE.

QPtrCollection::Item QGCache::find_other	(	const char *	key,
		bool	ref = TRUE
	)		const [protected]

QPtrCollection::Item QGCache::find_string	(	const QString &	key,

	)		[protected]

bool QGCache::insert_string	(	const QString &	key,
		QPtrCollection::Item	data,
		int	cost,
		int	priority
	)		[protected]

Inserts an item with data data into the cache using key key. The item has cost cost and priority priority.

Atención:

If this function returns FALSE, you must delete data yourself. Additionally, be very careful about using data after calling this function, as any other insertions into the cache, from anywhere in the application, or within Qt itself, could cause the data to be discarded from the cache, and the pointer to become invalid.
