NAME¶
CosNotifyFilter_MappingFilter - This module implements the OMG CosNotifyFilter::MappingFilter interface.DESCRIPTION¶
The main purpose of this module is to match events against associated constraints and return the value for the first constraint that returns true for the given event. If all constraints return false the default value will be returned. To get access to the record definitions for the structures use:EXPORTS¶
_get_constraint_grammar(MappingFilter) -> Grammar
Types:
MappingFilter = #objref
Grammar = string()
This operation returns which type of Grammar the MappingFilter uses. Currently,
only "EXTENDED_TCL" is supported.
Types:
MappingFilter = #objref
This readonly attribute maintains the CORBA::TypeCode of the default
value associated with the target object.
Types:
MappingFilter = #objref
This readonly attribute maintains the #any{} default value associated
with the target object.
Types:
MappingFilter = #objref
MappingConstraintPairSeq = [MappingConstraintPair]
MappingConstraintPair =
#'CosNotifyFilter_MappingConstraintPair'{constraint_expression, result_to_set}
constraint_expression = #'CosNotifyFilter_ConstraintExp'{event_types,
constraint_expr}
event_types = #'CosNotification_EventTypeSeq'{}
constraint_expr = string()
result_to_set = #any
Reply = MappingConstraintInfoSeq | {'EXCEPTION',
#'CosNotifyFilter_InvalidConstraint'{constr}} | {'EXCEPTION',
#'CosNotifyFilter_InvalidValue'{constr, value}}
constr = ConstraintExp
ConstraintExp = #'CosNotifyFilter_ConstraintExp'{event_types, constraint_expr}
event_types = #'CosNotification_EventTypeSeq'{}
constraint_expr = string()
MappingConstraintInfoSeq = [MappingConstraintInfo]
MappingConstraintInfo =
#'CosNotifyFilter_MappingConstraintInfo'{constraint_expression, constraint_id,
value}
constraint_expression = ConstraintExp
constraint_id = long()
value = #any
This operation add new mapping constraints, which will be used when trying to
override Quality of Service settings defined in the given event. If a
constraint return true the associated value will be returned, otherwise the
default value.
Types:
MappingFilter = #objref
ConstraintIDSeq = [ConstraintID]
ConstraintID = long()
MappingConstraintInfoSeq = [MappingConstraintInfo]
MappingConstraintInfo =
#'CosNotifyFilter_MappingConstraintInfo'{constraint_expression, constraint_id,
value}
constraint_expression = ConstraintExp
constraint_id = long()
value = #any
ConstraintInfoSeq = [ConstraintInfo]
ConstraintInfo = #'CosNotifyFilter_ConstraintInfo'{constraint_expression,
constraint_id}
constraint_expression = ConstraintExp

{'EXCEPTION', #'CosNotifyFilter_ConstraintNotFound'{id}} | {'EXCEPTION',
#'CosNotifyFilter_InvalidValue'{constr, value}}
constr = ConstraintExp
id = long()
value = #any
ConstraintExp = #'CosNotifyFilter_ConstraintExp'{event_types, constraint_expr}
event_types = #'CosNotification_EventTypeSeq'{}
constraint_expr = string()
The ConstraintIDSeq supplied should relate to constraints the caller
wishes to remove. If any of the supplied Id's are not found an exception will
be raised. This operation also accepts a sequence of
MappingConstraintInfo which will be added. If the target object cannot
modify the constraints as requested an exception is raised describing which
constraint, and why, could not be updated.
Types:
MappingFilter = #objref
ConstraintIDSeq = [ConstraintID]
ConstraintID = long()
Reply = MappingConstraintInfoSeq | {'EXCEPTION',
#'CosNotifyFilter_ConstraintNotFound'{id}}
MappingConstraintInfoSeq = [MappingConstraintInfo]
MappingConstraintInfo =
#'CosNotifyFilter_MappingConstraintInfo'{constraint_expression, constraint_id,
value}
constraint_expression = ConstraintExp
ConstraintExp = #'CosNotifyFilter_ConstraintExp'{event_types, constraint_expr}
event_types = #'CosNotification_EventTypeSeq'{}
constraint_expr = string()
constraint_id = id = long()
value = #any
When adding a new constraint a unique Id is returned, which is accepted as input
for this operation. The associated constraint is returned, but if no such Id
exists an exception is raised.
Types:
MappingFilter = #objref
MappingConstraintInfoSeq = [MappingConstraintInfo]
MappingConstraintInfo =
#'CosNotifyFilter_MappingConstraintInfo'{constraint_expression, constraint_id,
value}
constraint_expression = ConstraintExp
ConstraintExp = #'CosNotifyFilter_ConstraintExp'{event_types, constraint_expr}
event_types = #'CosNotification_EventTypeSeq'{}
constraint_expr = string()
constraint_id = long()
value = #any
This operation returns a sequence of all unique Id's associated with the target
object. If no constraint have been added the sequence will be empty.
Types:
MappingFilter = #objref
This operation removes all constraints associated with the target object.
Types:
MappingFilter = #objref
This operation terminates the target object. Remember to remove this Filter from
the objects it have been associated with.
Types:
MappingFilter = #objref
Event = #any
Reply = {boolean(), #any} | {'EXCEPTION',
#'CosNotifyFilter_UnsupportedFilterableData'{}}
This operation evaluates Any events with the Filter's constraints, and
returns the value to use. The value is the default value if all constraints
returns false and the value associated with the first constraint returning
true.
Types:
MappingFilter = #objref
Event = #'CosNotification_StructuredEvent'{}
Reply = {boolean(), #any} | {'EXCEPTION',
#'CosNotifyFilter_UnsupportedFilterableData'{}}
Similar to match/2 but accepts a structured event as input.
