    nsIMemoryReporterManager

    A service that provides methods for managing nsIMemoryReporter objects.
    Inherits from: 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.

    Method overview

    nsISimpleEnumerator enumerateMultiReporters();
    nsISimpleEnumerator enumerateReporters();
    void init();
    void registerMultiReporter(in nsIMemoryMultiReporter reporter);
    void registerReporter(in nsIMemoryReporter reporter);
    void unregisterMultiReporter(in nsIMemoryMultiReporter reporter);
    void unregisterReporter(in nsIMemoryReporter reporter);

    Attributes

    Attribute Type Description
    explicit PRInt64

    Gets the total size of explicit memory allocations, both at the operating system level (for example, via mmap, VirtualAlloc) and at the heap level (for example, via malloc(), calloc(), operator new).

    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.
