# CosNotifyFilter_FilterAdmin

### MODULE

CosNotifyFilter_FilterAdmin

### MODULE SUMMARY

This module implements the OMG CosNotifyFilter::FilterAdmin interface.

### DESCRIPTION

To get access to the record definitions for the structures use:
`-include_lib("cosNotification/include/*.hrl").`

All objects, which inherit this interface, export functions described in this module.

### EXPORTS

`add_filter(Object, Filter) -> FilterID`

Types:

`Object = #objref`
`Filter = #objref`
`FilterID = long()`

This operation connects a new `Filter` to the target object. This `Filter` will, together with other associated `Filters`, be used to select events to forward. A unique Id is returned and should be used if we no longer want to consult the given `Filter`.

`remove_filter(Object, FilterID) -> ok`

Types:

`Object = #objref`
`FilterID = long()`

If a certain `Filter` no longer should be associated with the target object this operation must be used. Events will no longer be tested against the `Filter` associated with the given Id.

`get_filter(Object, FilterID) -> Reply`

Types:

`Object = #objref`
`FilterID = long()`
`Reply = Filter | {'EXCEPTION', #'CosNotifyFilter_FilterNotFound'{}}`
`Filter = #objref`

If the target object is associated with a `Filter` matching the given Id the reference will be returned. If no such `Filter` is known by the target object an exception is raised.

`get_all_filters(Object) -> FilterIDSeq`

Types:

`Object = #objref`
`FilterIDSeq = [FilterID]`
`FilterID = long()`

Id's for all `Filter` objects associated with the target object is returned by this operation.

`remove_all_filters(Object) -> ok`

Types:

`Object = #objref`

If we want to remove all `Filters` associated with the target object we can use this function.
