Cache

class Cache(pointer: <Error class: unknown class><<Error class: unknown class>>) : ProxyInstance

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.

Functions

destroy

fun destroy()

Frees the memory allocated for the #GCache.

equals

open operator override fun equals(other: Any?): Boolean

Compare two proxy instances for equality. This will compare both the type of the instances, and their memory addresses.

hashCode

open override fun hashCode(): Int

insert

fun insert(key: <Error class: unknown class>? = null): <Error class: unknown class>?

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

fun keyForeach(func: HFunc)

Calls the given function for each of the keys in the #GCache.

remove

fun remove(value: <Error class: unknown class>? = null)

Decreases the reference count of the given value. If it drops to 0 then the value and its corresponding key are destroyed, using the

valueForeach

fun valueForeach(func: HFunc)

Calls the given function for each of the values in the #GCache.
