60 | <tt class="class">Filter</tt>s can be used by <tt class="class">Handler</tt>s and <tt class="class">Logger</tt>s for | |
61 | more sophisticated filtering than is provided by levels. The base filter | |
62 | class only allows events which are below a certain point in the logger | |
63 | hierarchy. For example, a filter initialized with "A.B" will allow events | |
64 | logged by loggers "A.B", "A.B.C", "A.B.C.D", "A.B.D" etc. but not "A.BB", | |
65 | "B.A.B" etc. If initialized with the empty string, all events are passed. | |

71 | <dd> | |
72 | Returns an instance of the <tt class="class">Filter</tt> class. If <var>name</var> is specified, | |
73 | it names a logger which, together with its children, will have its events | |
74 | allowed through the filter. If no name is specified, allows every event. | |

82 | Is the specified record to be logged? Returns zero for no, nonzero for | |
83 | yes. If deemed appropriate, the record may be modified in-place by this | |
