Cache

A GCache allows sharing of complex data structures, in order to save system resources.

GCache uses keys and values. A GCache key describes the properties of a particular resource. A GCache value is the actual resource.

GCache has been marked as deprecated, since this API is rarely used and not very actively maintained.

Constructors

this
this(GCache* gCache)

Sets our main struct and passes it to the parent class

this
this(GCacheNewFunc valueNewFunc, GCacheDestroyFunc valueDestroyFunc, GCacheDupFunc keyDupFunc, GCacheDestroyFunc keyDestroyFunc, GHashFunc hashKeyFunc, GHashFunc hashValueFunc, GEqualFunc keyEqualFunc)

Warning g_cache_new has been deprecated since version 2.32 and should not be used in newly-written code. Use a GHashTable instead Creates a new GCache.

Members

Functions

destroy
void destroy()

Warning g_cache_destroy has been deprecated since version 2.32 and should not be used in newly-written code. Use a GHashTable instead Frees the memory allocated for the GCache. Note that it does not destroy the keys and values which were contained in the GCache.

getCacheStruct
GCache* getCacheStruct()

Get the main Gtk struct

getStruct
void* getStruct()

the main Gtk struct as a void*

insert
void* insert(void* key)

Warning g_cache_insert has been deprecated since version 2.32 and should not be used in newly-written code. Use a GHashTable instead Gets the value corresponding to the given key, creating it if necessary. It first checks if the value already exists in the GCache, by using the key_equal_func function passed to g_cache_new(). If it does already exist it is returned, and its reference count is increased by one. If the value does not currently exist, if is created by calling the value_new_func. The key is duplicated by calling key_dup_func and the duplicated key and value are inserted into the GCache.

keyForeach
void keyForeach(GHFunc func, void* userData)

Warning g_cache_key_foreach has been deprecated since version 2.32 and should not be used in newly-written code. Use a GHashTable instead Calls the given function for each of the keys in the GCache. NOTE func is passed three parameters, the value and key of a cache entry and the user_data. The order of value and key is different from the order in which g_hash_table_foreach() passes key-value pairs to its callback function !

remove
void remove(void* value)

Warning g_cache_remove has been deprecated since version 2.32 and should not be used in newly-written code. Use a GHashTable instead Decreases the reference count of the given value. If it drops to 0 then the value and its corresponding key are destroyed, using the value_destroy_func and key_destroy_func passed to g_cache_new().

valueForeach
void valueForeach(GHFunc func, void* userData)

Warning g_cache_value_foreach has been deprecated since version 2.10 and should not be used in newly-written code. The reason is that it passes pointers to internal data structures to func; use g_cache_key_foreach() instead Calls the given function for each of the values in the GCache.
