    IMS Enterprise file enrolment plugin. This plugin lets the user specify an IMS Enterprise file to be processed. The IMS Enterprise file is mainly parsed on a regular cron, but can also be imported via the UI (Admin Settings).

    Class: enrol_imsenterprise_plugin  - X-Ref

    IMS Enterprise file enrolment plugin.

    cron()   X-Ref
    Read in an IMS Enterprise file.
    Originally designed to handle v1.1 files but should be able to handle
    earlier types as well, I believe.
    This cron feature has been converted to a scheduled task and it can now be scheduled
    from the UI.


    full_tag_found_in_cache($tagname, $latestline)   X-Ref
    Check if a complete tag is found in the cached data, which usually happens
    when the end of the tag has only just been loaded into the cache.

    param: string $tagname Name of tag to look for
    param: string $latestline The very last line in the cache (used for speeding up the match)
    return: bool|string false, or the contents of the tag (including start and end).

    remove_tag_from_cache($tagname)   X-Ref
    Remove complete tag from the cached data (including all its contents) - so
    that the cache doesn't grow to unmanageable size

    param: string $tagname Name of tag to look for

    get_recstatus($tagdata, $tagname)   X-Ref
    Very simple convenience function to return the "recstatus" found in person/group/role tags.
    1=Add, 2=Update, 3=Delete, as specified by IMS, and we also use 0 to indicate "unspecified".

    param: string $tagdata the tag XML data
    param: string $tagname the name of the tag we're interested in
    return: int recstatus value

    process_group_tag($tagcontents)   X-Ref
    Process the group tag. This defines a Moodle course.

    param: string $tagcontents The raw contents of the XML element

    process_person_tag($tagcontents)   X-Ref
    Process the person tag. This defines a Moodle user.

    param: string $tagcontents The raw contents of the XML element

    process_membership_tag($tagcontents)   X-Ref
    Process the membership tag. This defines whether the specified Moodle users
    should be added/removed as teachers/students.

    param: string $tagcontents The raw contents of the XML element

    process_properties_tag($tagcontents)   X-Ref
    Process the properties tag. The only data from this element
    that is relevant is whether a <target> is specified.

    param: string $tagcontents The raw contents of the XML element

    log_line($string)   X-Ref
    Store logging information. This does two things: uses the {@link mtrace()}
    function to print info to screen/STDOUT, and also writes log to a text file
    if a path has been specified.

    param: string $string Text to write (newline will be added automatically)

    decode_timeframe($string)   X-Ref
    Process the INNER contents of a <timeframe> tag, to return beginning/ending dates.

    param: string $string tag to decode.
    return: stdClass beginning and/or ending is returned, in unix time, zero indicating not specified.

    load_role_mappings()   X-Ref
    Load the role mappings (from the config), so we can easily refer to
    how an IMS-E role corresponds to a Moodle role


    load_course_mappings()   X-Ref
    Load the name mappings (from the config), so we can easily refer to
    how an IMS-E course properties corresponds to a Moodle course properties


    get_default_category_id()   X-Ref
    Get the default category id (often known as 'Miscellaneous'),
    statically cached to avoid multiple DB lookups on big imports.

    return: int id of default category.

    get_category_from_group($categories)   X-Ref
    Find the category using idnumber or name.

    param: array $categories List of categories
    return: int id of category found.

    can_delete_instance($instance)   X-Ref
    Is it possible to delete enrol instance via standard UI?

    param: object $instance
    return: bool

    can_hide_show_instance($instance)   X-Ref
    Is it possible to hide/show enrol instance via standard UI?

    param: stdClass $instance
    return: bool

    enrol_imsenterprise_allow_group_member_remove($itemid, $groupid, $userid)   X-Ref
    Called whenever anybody tries (from the normal interface) to remove a group
    member which is registered as being created by this component. (Not called
    when deleting an entire group or course at once.)

    param: int $itemid Item ID that was stored in the group_members entry
    param: int $groupid Group ID
    param: int $userid User ID being removed from group
    return: bool True if the remove is permitted, false to give an error
