class IPropertyManager(Interface):

    """
    The PropertyManager mixin class provides an object with
    transparent property management. An object which wants to
    have properties should inherit from PropertyManager.

    An object may specify that it has one or more predefined
    properties, by specifying an _properties structure in its
    class::

      _properties=({'id':'title', 'type': 'string', 'mode': 'w'},
                   {'id':'color', 'type': 'string', 'mode': 'w'},
                   )

    The _properties structure is a sequence of dictionaries, where
    each dictionary represents a predefined property. Note that if a
    predefined property is defined in the _properties structure, you
    must provide an attribute with that name in your class or instance
    that contains the default value of the predefined property.

    Each entry in the _properties structure must have at least an 'id'
    and a 'type' key. The 'id' key contains the name of the property,
    and the 'type' key contains a string representing the object's type.
    The 'type' string must be one of the values: 'float', 'int', 'long',
    'string', 'lines', 'text', 'date', 'tokens', 'selection', or
    'multiple section'.

    For 'selection' and 'multiple selection' properties, there is an
    addition item in the property dictionay, 'select_variable' which
    provides the name of a property or method which returns a list of
    strings from which the selection(s) can be chosen.

    Each entry in the _properties structure may *optionally* provide a
    'mode' key, which specifies the mutability of the property. The 'mode'
    string, if present, must contain 0 or more characters from the set
    'w','d'.

    A 'w' present in the mode string indicates that the value of the
    property may be changed by the user. A 'd' indicates that the user
    can delete the property. An empty mode string indicates that the
    property and its value may be shown in property listings, but that
    it is read-only and may not be deleted.

    Entries in the _properties structure which do not have a 'mode' key
    are assumed to have the mode 'wd' (writeable and deleteable).

    To fully support property management, including the system-provided
    tabs and user interfaces for working with properties, an object which
    inherits from PropertyManager should include the following entry in
    its manage_options structure::

      {'label':'Properties', 'action':'manage_propertiesForm',}

    to ensure that a 'Properties' tab is displayed in its management
    interface. Objects that inherit from PropertyManager should also
    include the following entry in its __ac_permissions__ structure::

      ('Manage properties', ('manage_addProperty',
                             'manage_editProperties',
                             'manage_delProperties',
                             'manage_changeProperties',)),
