Description

GdomeDocumentFragment is a "lightweight" or "minimal" GdomeDocument object. It is common to want to be able to extract a portion of a document's tree or to create a new fragment of a document. Imagine implementing a user command like cut or rearranging a document by moving fragments around. It is desirable to have an object which can hold such fragments and it is quite natural to use a GdomeNode for this purpose. While it is true that a GdomeDocument object could fulfill this role, a GdomeDocument object can potentially be a heavyweight object. What is really needed for this is a very lightweight object. GdomeDocumentFragment is such an object.

Furthermore, various operations -- such as inserting nodes as children of another GdomeNode -- may take GdomeDocumentFragment objects as arguments; this results in all the child nodes of the GdomeDocumentFragment being moved to the child list of this node.

The children of a GdomeDocumentFragment node are zero or more nodes representing the tops of any sub-trees defining the structure of the document. GdomeDocumentFragment nodes do not need to be well-formed XML documents (although they do need to follow the rules imposed upon well-formed XML parsed entities, which can have multiple top nodes). For example, a GdomeDocumentFragment might have only one child and that child node could be a GdomeText node. Such a structure model represents neither an HTML document nor a well-formed XML document.

When a GdomeDocumentFragment is inserted into a GdomeDocument (or indeed any other GdomeNode that may take children) the children of the GdomeDocumentFragment and not the GdomeDocumentFragment itself are inserted into the GdomeNode. This makes the GdomeDocumentFragment very useful when the user wishes to create nodes that are siblings; the GdomeDocumentFragment acts as the parent of these nodes so that the user can use the standard methods from the GdomeNode interface, such as gdome_n_insertBefore() and gdome_n_appendChild().

                                             GdomeException *exc);

Makes a duplicate of this node, i.e., serves as a generic copy constructor for nodes. The duplicate node has no parent; (parentNode is NULL). GDOME_DOCUMENT_TYPE_NODE, GDOME_NOTATION_NODE and GDOME_ENTITY_NODE nodes are not supported.

GDOME_NOT_SUPPORTED_ERR: Raised if the type of node being cloned is not supported.

self : Node Object ref
deep : If true, recursively clone the subtree under the specified node; if false, clone only the node itself (and its attributes, if it is an Element).
exc : Exception Object ref
Returns : the duplicate node.


gdome_df_normalize ()

                                             GdomeException *exc);

Tests whether the DOM implementation implements a specific feature and that feature is supported by this node.

self : Node Object ref
feature : The name of the feature to test.
version : This is the version number of the feature to test. In Level 2, version 1, this is the string "2.0". If the version is not specified, supporting any version of the feature will cause the method to return TRUE.
exc : Exception Object ref
Returns : TRUE if the specified feature is supported on this node, FALSE otherwise.


gdome_df_namespaceURI ()

GdomeDOMString* gdome_df_namespaceURI       (GdomeDocumentFragment *self,
                                             GdomeException *exc);

self : Node Objects ref
exc : Exception Object ref
Returns : the namespace URI of this node, or NULL if it is unspecified. For nodes of any type other than GDOME_ELEMENT_NODE and GDOME_ATTRIBUTE_NODE and nodes created with a DOM Level 1 method, this is always NULL.

gdome_df_set_prefix ()

void        gdome_df_set_prefix             (GdomeDocumentFragment *self,
                                             GdomeDOMString *prefix,
                                             GdomeException *exc);

exc : Exception Object ref


gdome_df_localName ()

GdomeDOMString* gdome_df_localName          (GdomeDocumentFragment *self,
                                             GdomeException *exc);

gdome_df_addEventListener ()

void        gdome_df_addEventListener       (GdomeDocumentFragment *self,
                                             GdomeDOMString *type,
                                             GdomeEventListener *listener,
                                             GdomeBoolean useCapture,
                                             GdomeException *exc);

This method allows the registration of event listeners on the event target. If an EventListener is added to an EventTarget while it is processing an event, it will not be triggered by the current actions but may be triggered during a later stage of event flow, such as the bubbling phase. If multiple identical EventListeners are registered on the same EventTarget with the same parameters the duplicate instances are discarded. They do not cause the EventListener to be called twice and since they are discarded they do not need to be removed with the removeEventListener method.

self : Node Object ref
type : the event type for which the user is registering
listener : the listener parameter takes an interface implemented by the user which contains the methods to be called when the event occurs.
useCapture : if TRUE, useCapture indicates that the user wishes to initiate capture. After initiating capture, all events of the specified type will be dispatched to the registered EventListener before being dispatched to any EventTargets beneath them in the tree. Events which are bubbling upward through the tree will not trigger an EventListener designated to use capture.
exc : Exception Object ref


gdome_df_removeEventListener ()

void        gdome_df_removeEventListener    (GdomeDocumentFragment *self,
                                             GdomeDOMString *type,
                                             GdomeEventListener *listener,
                                             GdomeBoolean useCapture,
                                             GdomeException *exc);

This method allows the removal of event listeners from the event target. If an EventListener is removed from an EventTarget while it is processing an event, it will not be triggered by the current actions. EventListeners can never be invoked after being removed. Calling removeEventListener with arguments which do not identify any currently registered EventListener on the EventTarget has no effect.

self : Node Object ref
type : Specifies the event type of the EventListener being removed.
listener : The EventListener parameter indicates the EventListener to be removed.
useCapture : Specifies whether the EventListener being removed was registered as a capturing listener or not. If a listener was registered twice, one with capture and one without, each must be removed separately. Removal of a capturing listener does not affect a non-capturing version of the same listener, and vice versa.
exc : Exception Object ref


gdome_df_dispatchEvent ()

GdomeBoolean gdome_df_dispatchEvent         (GdomeDocumentFragment *self,
                                             GdomeEvent *evt,
                                             GdomeException *exc);

This method allows the dispatch of events into the implementations event model. Events dispatched in this manner will have the same capturing and bubbling behavior as events dispatched directly by the implementation. The target of the event is the EventTarget on which dispatchEvent is called.

GDOME_UNSPECIFIED_EVENT_TYPE_ERR: Raised if the Event's type was not specified by initializing the event before dispatchEvent was called. Specification of the Event's type as NULL or an empty string will also trigger this exception.

self : Node Object ref
evt : Specifies the event type, behavior, and contextual information to be used in processing the event.
exc : Exception Object ref
Returns : if preventDefault was called the value is FALSE, else the value is TRUE.


gdome_df_subTreeDispatchEvent ()

void        gdome_df_subTreeDispatchEvent   (GdomeDocumentFragment *self,
                                             GdomeEvent *evt,
                                             GdomeException *exc);

This method allows the dispatch of events into the implementations event model. Events dispatched in this manner will have the same capturing and bubbling behavior as events dispatched directly by the implementation. The target of the event is any nodes in the subtree of the EventTarget on which dispatchEvent is called.

GDOME_UNSPECIFIED_EVENT_TYPE_ERR: Raised if the Event's type was not specified by initializing the event before dispatchEvent was called. Specification of the Event's type as NULL or an empty string will also trigger this exception.

self : Node Object ref
evt : Specifies the event type, behavior, and contextual information to be used in processing the event.
exc : Exception Object ref

                                             GdomeException *exc);

Tests if a newChild can be added in the child list of this node.

self : Node Object ref
newChild : The Node Object ref of the node to test
exc : Exception Object ref
Returns : TRUE if newChild can be added, FALSE otherwise.
