// This file defines the window collector class, which monitors window
|
|
// creation, opening, closing, and destruction, and records the events into
|
|
// the metrics service. This information provides additional context for loads
|
|
// into each window.
|
|
//
|
|
// The window collector also manages the list of assigned window ids, which
|
|
// are shared by all interested collectors.

//
|
|
// Event descriptions:
|
|
//
|
|
// <window action="create"/>: logged on new window creation.
|
|
// This window can correspond to a toplevel window or to a subframe.
|
|
// Attributes:
|
|
// windowid: The id of the new window (uint16)
|
|
// parent: The id of the window's parent (uint16)
|
|
// chrome: Set to true if the window has a chrome docshell (boolean)
|
|
//
|
|
// <window action="open"/>: logged when window.open() is called.
|
|
// This will be logged immediately following <windowcreate/> when a toplevel
|
|
// window is opened. It will never be logged for subframe windows.
|
|
// Attributes:
|
|
// windowid: The id of the opened window (uint16)
|
|
// opener: The id of the window's opener (uint16)
|
|
//
|
|
// <window action="close"/>: logged when a toplevel window is closed.
|
|
// Attributes:
|
|
// windowid: The id of the closed window (uint16)
|
|
//
|
|
// <window action="destroy"/>: logged when a window is destroyed.
|
|
// Attributes:
|
|
// windowid: The id of the destroyed window (uint16).
