Companion

object Companion : RecordCompanion<HashTable, <Error class: unknown class>>

Functions

Destroys all keys and values in the #GHashTable and decrements its reference count by 1. If keys and/or values are dynamically allocated, you should either free them first or create the #GHashTable with destroy notifiers using g_hash_table_new_full(). In the latter case the destroy functions you supplied will be called on all keys and values during the destruction phase.

foreach

fun foreach(hashTable: HashTable, func: HFunc)

Calls the given function for each of the key/value pairs in the #GHashTable. The function is passed the key and value of each pair, and the given @user_data parameter. The hash table may not be modified while iterating over it (you can't add/remove items). To remove all items matching a predicate, use g_hash_table_foreach_remove().

foreachRemove

fun foreachRemove(hashTable: HashTable, func: HRFunc): <Error class: unknown class>

Calls the given function for each key/value pair in the #GHashTable. If the function returns true, then the key/value pair is removed from the #GHashTable. If you supplied key or value destroy functions when creating the #GHashTable, they are used to free the memory allocated for the removed keys and values.

foreachSteal

fun foreachSteal(hashTable: HashTable, func: HRFunc): <Error class: unknown class>

Calls the given function for each key/value pair in the #GHashTable. If the function returns true, then the key/value pair is removed from the #GHashTable, but no key or value destroy functions are called.

newSimilar

fun newSimilar(otherHashTable: HashTable): HashTable

Creates a new #GHashTable like g_hash_table_new_full() with a reference count of 1.

ref

fun ref(hashTable: HashTable): HashTable

Atomically increments the reference count of @hash_table by one. This function is MT-safe and may be called from any thread.

removeAll

fun removeAll(hashTable: HashTable)

Removes all keys and their associated values from a #GHashTable.

size

fun size(hashTable: HashTable): <Error class: unknown class>

Returns the number of elements contained in the #GHashTable.

stealAll

fun stealAll(hashTable: HashTable)

Removes all keys and their associated values from a #GHashTable without calling the key and value destroy functions.

unref

fun unref(hashTable: HashTable)

Atomically decrements the reference count of @hash_table by one. If the reference count drops to 0, all keys and values will be destroyed, and all memory allocated by the hash table is released. This function is MT-safe and may be called from any thread.

wrapRecordPointer

open override fun wrapRecordPointer(pointer: <Error class: unknown class><out <Error class: unknown class>>): HashTable

Wrap a CPointer pointing to a record of this type into its wrapper class.
