Description

The GdomeNodeList interface provides the abstraction of an ordered collection of nodes, without defining or constraining how this collection is implemented. GdomeNodeList objects in the DOM are live.

The items in the GdomeNodeList are accessible via an integral index, starting from 0.

gdome_nl_ref ()

void        gdome_nl_ref                    (GdomeNodeList *self,
                                             GdomeException *exc);

Increase the reference count of the specified NodeList.

self : NodeList Object ref
exc : Exception Object ref

gdome_nl_unref ()

void        gdome_nl_unref                  (GdomeNodeList *self,
                                             GdomeException *exc);

Decrease the reference count of the specified NodeList. Free the NodeList structure if the specified NodeList will have zero reference.

self : NodeList Object ref
exc : Exception Object ref

gdome_nl_query_interface ()

gpointer    gdome_nl_query_interface        (GdomeNodeList *self,
                                             const char *interface,
                                             GdomeException *exc);

self : NodeList Object ref
interface : interface needed
exc : Exception Object ref
Returns : a reference to this object that implements the interface needed, or NULL if the interface is not supported by this Object.

gdome_nl_item ()

GdomeNode*  gdome_nl_item                   (GdomeNodeList *self,
                                             gulong index,
                                             GdomeException *exc);

self : NodeList Object ref
index : Index into the collection
exc : Exception Object ref
Returns : the indexth item in the collection. If index is greater than or equal to the number of nodes in the list, this returns NULL.

gdome_nl_length ()

gulong      gdome_nl_length                 (GdomeNodeList *self,
                                             GdomeException *exc);

self : NodeList Object ref
exc : Exception Object ref
Returns : the number of nodes in the list. The range of valid child node indices is 0 to length-1 inclusive.
