NAME

6       CosNotifyFilter_MappingFilter - This module implements the OMG CosNoti‐
7       fyFilter::MappingFilter interface.
8

DESCRIPTION

10       The main purpose of this module is to match events  against  associated
11       constraints  and return the value for the first constraint that returns
12       true for the given event. If all constraints return false  the  default
13       value will be returned.
14
15       To get access to the record definitions for the structures use:
16       -include_lib("cosNotification/include/*.hrl").

EXPORTS

19       _get_constraint_grammar(MappingFilter) -> Grammar
20
21              Types:
22
23                 MappingFilter = #objref
24                 Grammar = string()
25
26              This  operation  returns which type of Grammar the MappingFilter
27              uses. Currently, only "EXTENDED_TCL" is supported.

31              Types:
32
33                 MappingFilter = #objref
34
35              This readonly attribute maintains  the  CORBA::TypeCode  of  the
36              default value associated with the target object.
37
38       _get_default_value(MappingFilter) -> #any
39
40              Types:
41
42                 MappingFilter = #objref
43
44              This readonly attribute maintains the #any{} default value asso‐
45              ciated with the target object.

75
76              This  operation  add new mapping constraints, which will be used
77              when trying to override Quality of Service settings  defined  in
78              the  given  event.  If  a  constraint return true the associated
79              value will be returned, otherwise the default value.

112              The  ConstraintIDSeq  supplied  should relate to constraints the
113              caller wishes to remove. If any of the  supplied  Id's  are  not
114              found an exception will be raised. This operation also accepts a
115              sequence of MappingConstraintInfo which will be  added.  If  the
116              target  object  cannot  modify  the  constraints as requested an
117              exception is raised describing which constraint, and why,  could
118              not be updated.

139
140              When adding a new constraint a unique Id is returned,  which  is
141              accepted  as input for this operation. The associated constraint
142              is returned, but if no such Id exists an exception is raised.

160              This operation returns a sequence of all unique Id's  associated
161              with  the  target  object.  If no constraint have been added the
162              sequence will be empty.

179              This  operation terminates the target object. Remember to remove
180              this Filter from the objects it have been associated with.

191              This  operation  evaluates  Any  events  with  the Filter's con‐
192              straints, and returns the value to use. The value is the default
193              value  if all constraints returns false and the value associated
194              with the first constraint returning true.
