Properties:

• public Cache cache { get; construct; }
  The Cache being used for this keys table.
• public string key_column_name { get; construct; }
  The column name for the keys.
• public string table_name { get; construct; }
  The table name of this keys table.
• public string value_column_name { get; construct; }
  The column name for the values.

Creation methods:

• public CacheKeys (Cache cache, string table_name, string key_column_name, string value_column_name)
  Creates a new CacheKeys, which will operate with table_name, using column key_column_name to store keys and value_column_name to store values.

Methods:

• public bool count_keys_sync (out int64 out_n_stored, Cancellable? cancellable = null) throws Error
  Counts how many keys the this stores and set it to the out_n_stored.
• public bool foreach_sync (CacheKeysForeachFunc func, Cancellable? cancellable = null) throws Error
  Calls func for each stored key in the this, providing information about its value and reference count.
• public unowned Cache get_cache ()
  Gets an Cache, with which the this had been created.
• public unowned string get_key_column_name ()
  Gets a key column name, with which the this had been created.
• public bool get_ref_count_sync (string key, out uint out_ref_count, Cancellable? cancellable = null) throws Error
  Gets currently stored reference count for the key.
• public bool get_sync (string key, out string out_value, Cancellable? cancellable = null) throws Error
  Gets a stored value with given key, which had been previously put into the this with put_sync.
• public unowned string get_table_name ()
  Gets a table name, with which the this had been created.
• public unowned string get_value_column_name ()
  Get a value column name, with which the this had been created.
• public bool init_table_sync (Cancellable? cancellable = null) throws Error
  Initializes table in the corresponding Cache.
• public bool put_sync (string key, string value, uint inc_ref_counts, Cancellable? cancellable = null) throws Error
  Puts the key and value into the this.
• public bool remove_all_sync (Cancellable? cancellable = null) throws Error
  Removes all stored keys from the this .
• public bool remove_sync (string key, uint dec_ref_counts, Cancellable? cancellable = null) throws Error
  Dereferences use count of the key by dec_ref_counts and removes it from the cache when the reference count reaches zero.

Signals:

• public virtual signal void changed ()
  A signal emitted when the stored keys changed, aka when a new key is added or when an existing key is removed.
