nsIMemoryReporter objects.
nsISupports
Last changed in Gecko 1.9 (Firefox 3)Implemented by @mozilla.org/memory-reporter-manager;1 as a service:
var reporterManager = Components.classes["@mozilla.org/memory-reporter-manager;1"]
.getService(Components.interfaces.nsIMemoryReporterManager);
Each memory reporter object, which implements nsiMemoryReporter interface, provides information for a given code area. Each code area is identified by a unique path string, which is displayed in about:memory.

Attributes
| Attribute | Type | Description |
explicit |
PRInt64 |
Gets the total size of explicit memory allocations, both at the operating system level (for example, via Note: It covers all heap allocations, but will miss any Operating System level ones not covered by memory reporters.
This reporter is special-cased because it is interesting, and is moderately difficult to compute in JavaScript. -1 means unknown. Read only. |
resident |
PRInt64 |
Gets the resident size (that is RSS, physical memory used). This reporter is special-cased because it is interesting, is available on all platforms, and returns a meaningful result on all common platforms. -1 means unknown. Read only. |
