    nsINavHistoryQuery

    Encapsulates all the query parameters you're likely to need when building up history UI. All parameters are ANDed together.
    1.0

    Inherits from: nsISupports Last changed in Gecko 2.0 (Firefox 4 / Thunderbird 3.3 / SeaMonkey 2.1)

    The nsINavHistoryQuery is not intended to be a super-general query mechanism. This was designed so that most queries can be done in only one SQL query. This is important because, if the user has their profile on a networked drive, query latency can be non-negligible

    Attributes

    Attribute Type Description
    absoluteBeginTime PRTime Read only: Retrieves the begin time value that the currently loaded reference points + offset resolve to.
    absoluteEndTime PRTime Read only: Retrieves the end time value that the currently loaded reference points + offset resolve to.
    annotation AUTF8String The annotation name.
    annotationIsNot boolean Test for existance or non-existance of a given annotation. We don't currently support >1 annotation name per query. If annotationIsNot is true, we test for the non-existance of the specified annotation. Testing for not annotation will do the same thing as a normal query and remove everything that doesn't have that annotation. Asking for things that DO have a given annotation is a little different. It also includes things that have never been visited. This allows place queries to be returned (which might include bookmark folders -- use the bookmark service's GetFolderURI) as well as anything else that may have been tagged with an annotation. This will only work for RESULTS_AS_URI since there will be no visits for these items.
    beginTime PRTime Begin time range for results (INCLUSIVE).
    beginTimeReference long One of the constants TIME_RELATIVE_* which indicates how to interpret the corresponding begin time value.
    domain AUTF8String This is the host or domain name (controlled by domainIsHost). When domainIsHost, domain only does exact matching on host names. Otherwise, it will return anything whose host name ends in domain.

    This one is a little different than most. Setting it to an empty string is a real query and will match any URI that has no host name (local files and such). Set this to NULL (in C++ use SetIsVoid) if you don't want domain matching.

    domainIsHost boolean This controls the meaning of domain, and whether it is an exact match domainIsHost = true, or hierarchical (= false).
    endTime PRTime End time range for results (INCLUSIVE).
    endTimeReference long One of the constants TIME_RELATIVE_* which indicates how to interpret the corresponding end time value.
    folderCount long Read only: Count of folders.
    hasAnnotation boolean Read only: Whether or not, annotation exists.
    hasBeginTime boolean Read only: Whether or not, the corresponding begin time is considered.
    hasDomain boolean Read only: Whether or not, domain exists.
    hasEndTime boolean Read only: Whether or not, the corresponding end time is considered.
    hasSearchTerms boolean Read only: Whether or not, text search terms exists.
    hasUri boolean Read only: Whether or not, uri exists.

    maxVisits

    long Set upper limits for how many times an item has been visited. The default value is "-1", and in that case all items are matched regardless of their visit count.

    minVisits

    long Set lower limits for how many times an item has been visited. The default value is "-1", and in that case all items are matched regardless of their visit count.
    onlyBookmarked boolean When set, returns only bookmarked items, when unset, returns anything. Setting this is equivalent to listing all bookmark folders in the folders parameter.
    searchTerms AString Text search terms.
    tags nsIVariant

    A list of tags to use for filtering query results. This attribute must be an array of strings. Duplicate tags may be specified, but when reading the list, only unique tags are returned.

    When called as a getter, this returns an array of strings sorted in ascending lexicographical (alphabetical) order.

    This array may be empty, in which case no filtering by tags is performed.

    To search for items that are tagged with any given tags instead of all, multiple queries may be passed to the nsINavHistoryService method nsINavHistoryService.executeQueries().

    tagsAreNot boolean If true, the results include only items that are not tagged with the specified tags. If false, only tags in the tags list are included in the results.
    uri nsIURI This is a URI to match, to, for example, find out every time you visited a given URI. Use uriIsPrefix to control whether this is an exact match.
    uriIsPrefix boolean Controls the interpretation of uri. When unset (default), the URI will request an exact match of the specified URI. When set, any history entry beginning in uri will match. For example http://bar.com/foo will match http://bar.com/foo as well as http://bar.com/foo/baz.gif.

    Constants

    Constant Value Description
    TIME_RELATIVE_EPOCH 0 Default value. The time is relative to Jan 1 1970 GMT, (this is a normal PRTime). As a special case, a 0 time relative to TIME_RELATIVE_EPOCH indicates that the time is not part of the query. This is the default, so an empty query will match any time.
    TIME_RELATIVE_TODAY 1 The time is relative to this morning at midnight. Normally used for queries relative to today. For example, a "past week" query would be (today-6 days -> today+1 day).
    TIME_RELATIVE_NOW 2 The time is relative to right now.

    Note: PRTime is in MICROseconds since 1 Jan 1970. JavaScript date objects are expressed in MILLIseconds since 1 Jan 1970.

    Methods

    getFolders()

    This method retrieves all the folders with the folder count.

     void getFolders(
       [optional] out unsigned long count,
       [retval,array,size_is(count)] out long long folders
     );
    
    Parameters
    count Optional
    The count of the folders. This optional parameter was required prior to Gecko 2.0.
    folders
    The retrieved folders.

    setFolders()

    This method sets the folders with the given folder count.

     void setFolders(
       [const,array, size_is(folderCount)] in long long folders,
       in unsigned long folderCount
     );
    
    Parameters
    count
    The count of the folders.
    folders
    The folders to be set.

    clone()

    This method creates a new query item with the same parameters of this one.

     nsINavHistoryQuery clone();
    
    Parameters

    None.

    Return value

    Returns the newly created cloned query.

    Requires Gecko 2.0 (Firefox 4 / Thunderbird 3.3 / SeaMonkey 2.1)

    getTransitions()

    Get the transitions set for this query.

    void getTransitions(
      out unsigned long count, Optional
      [retval,array,size_is(count)] out unsigned long transitions
    );
    
    Parameters
    count Optional
    The number of transitions
    transitions
    Missing Description

    Requires Gecko 2.0 (Firefox 4 / Thunderbird 3.3 / SeaMonkey 2.1)

    setTransitions()

    When the set of transitions is nonempty, results are limited to pages which have at least one visit for each of the transition types.

    Limit results to the specified list of transition types.

    void setTransitions(
      [const,array, size_is(count)] in unsigned long transitions,
      in unsigned long count
    );
    
    Parameters
    transitions
    Missing Description.
    count
