|
|
* State Transition Flags
|
|
*
|
|
* These flags indicate the various states that requests may transition
|
|
* through as they are being loaded. These flags are mutually exclusive.
|
|
*
|
|
* For any given request, onStateChange is called once with the STATE_START
|
|
* flag, zero or more times with the STATE_TRANSFERRING flag or once with the
|
|
* STATE_REDIRECTING flag, and then finally once with the STATE_STOP flag.
|
|
* NOTE: For document requests, a second STATE_STOP is generated (see the
|
|
* description of STATE_IS_WINDOW for more details).
|
|
*
|
|
* STATE_START
|
|
* This flag indicates the start of a request. This flag is set when a
|
|
* request is initiated. The request is complete when onStateChange is
|
|
* called for the same request with the STATE_STOP flag set.
|
|
*
|
|
* STATE_REDIRECTING
|
|
* This flag indicates that a request is being redirected. The request
|
|
* passed to onStateChange is the request that is being redirected. When a
|
|
* redirect occurs, a new request is generated automatically to process the
|
|
* new request. Expect a corresponding STATE_START event for the new
|
|
* request, and a STATE_STOP for the redirected request.
|
|
*
|
|
* STATE_TRANSFERRING
|
|
* This flag indicates that data for a request is being transferred to an
|
|
* end consumer. This flag indicates that the request has been targeted,
|
|
* and that the user may start seeing content corresponding to the request.
|
|
*
|
|
* STATE_NEGOTIATING
|
|
* This flag is not used.
|
|
*
|
|
* STATE_STOP
|
|
* This flag indicates the completion of a request. The aStatus parameter
|
|
* to onStateChange indicates the final status of the request.

/**
|
|
* State Type Flags
|
|
*
|
|
* These flags further describe the entity for which the state transition is
|
|
* occuring. These flags are NOT mutually exclusive (i.e., an onStateChange
|
|
* event may indicate some combination of these flags).
|
|
*
|
|
* STATE_IS_REQUEST
|
|
* This flag indicates that the state transition is for a request, which
|
|
* includes but is not limited to document requests. (See below for a
|
|
* description of document requests.) Other types of requests, such as
|
|
* requests for inline content (e.g., images and stylesheets) are
|
|
* considered normal requests.
|
|
*
|
|
* STATE_IS_DOCUMENT
|
|
* This flag indicates that the state transition is for a document request.
|
|
* This flag is set in addition to STATE_IS_REQUEST. A document request
|
|
* supports the nsIChannel interface and its loadFlags attribute includes
|
|
* the nsIChannel::LOAD_DOCUMENT_URI flag.
|
|
*
|
|
* A document request does not complete until all requests associated with
|
|
* the loading of its corresponding document have completed. This includes
|
|
* other document requests (e.g., corresponding to HTML <iframe> elements).
|
|
* The document corresponding to a document request is available via the
|
|
* DOMWindow attribute of onStateChange's aWebProgress parameter.
|
|
*
|
|
* STATE_IS_NETWORK
|
|
* This flag indicates that the state transition corresponds to the start
|
|
* or stop of activity in the indicated nsIWebProgress instance. This flag
|
|
* is accompanied by either STATE_START or STATE_STOP, and it may be
|
|
* combined with other State Type Flags.
|
|
*
|
|
* Unlike STATE_IS_WINDOW, this flag is only set when activity within the
|
|
* nsIWebProgress instance being observed starts or stops. If activity
|
|
* only occurs in a child nsIWebProgress instance, then this flag will be
|
|
* set to indicate the start and stop of that activity.
|
|
*
|
|
* For example, in the case of navigation within a single frame of a HTML
|
|
* frameset, a nsIWebProgressListener instance attached to the
|
|
* nsIWebProgress of the frameset window will receive onStateChange calls
|
|
* with the STATE_IS_NETWORK flag set to indicate the start and stop of
|
|
* said navigation. In other words, an observer of an outer window can
|
|
* determine when activity, that may be constrained to a child window or
|
|
* set of child windows, starts and stops.
|
|
*
|
|
* STATE_IS_WINDOW
|
|
* This flag indicates that the state transition corresponds to the start
|
|
* or stop of activity in the indicated nsIWebProgress instance. This flag
|
|
* is accompanied by either STATE_START or STATE_STOP, and it may be
|
|
* combined with other State Type Flags.
|
|
*
|
|
* This flag is similar to STATE_IS_DOCUMENT. However, when a document
|
|
* request completes, two onStateChange calls with STATE_STOP are
|
|
* generated. The document request is passed as aRequest to both calls.
|
|
* The first has STATE_IS_REQUEST and STATE_IS_DOCUMENT set, and the second
|
|
* has the STATE_IS_WINDOW flag set (and possibly the STATE_IS_NETWORK flag
|
|
* set as well -- see above for a description of when the STATE_IS_NETWORK
|
|
* flag may be set). This second STATE_STOP event may be useful as a way
|
|
* to partition the work that occurs when a document request completes.
