Gtk.TreeModelFilter.clear_cache

### Method

# Gtk TreeModelFilterclear_cache

#### Declaration [src]

    void
    gtk_tree_model_filter_clear_cache (
      GtkTreeModelFilter* filter
    )

#### Description [src]

This function should almost never be called. It clears the `filter` of any cached iterators that haven’t been reffed with gtk_tree_model_ref_node(). This might be useful if the child model being filtered is static (and doesn’t change often) and there has been a lot of unreffed access to nodes. As a side effect of this function, all unreffed iters will be invalid.
