<module>CosNotifyFilter_FilterAdmin</module>
<modulesummary>This module implements the OMG CosNotifyFilter::FilterAdmin interface.</modulesummary>
<description>
<p>To get access to the record definitions for the structures use: <br></br>
<c>-include_lib("cosNotification/include/*.hrl").</c></p>
<p>All objects, which inherit this interface, export functions described in this module.</p>
</description>
<funcs>
<func>
<name>add_filter(Object, Filter) -> FilterID</name>
<fsummary>Add a new filter to the target object</fsummary>
<type>
<v>Object = #objref</v>
<v>Filter = #objref</v>
<v>FilterID = long()</v>
</type>
<desc>
<p>This operation connects a new <c>Filter</c> to the target object. This <c>Filter</c> will, together
with other associated <c>Filters</c>, 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 <c>Filter</c>.</p>
</desc>
</func>
<func>
<name>remove_filter(Object, FilterID) -> ok</name>
<fsummary>Remove a filter associated with the target object</fsummary>
<type>
<v>Object = #objref</v>
<v>FilterID = long()</v>
</type>
<desc>
<p>If a certain <c>Filter</c> no longer should be associated with the target object
this operation must be used. Events will no longer be tested against the <c>Filter</c>
associated with the given Id.</p>
</desc>
</func>
<func>
<name>get_filter(Object, FilterID) -> Reply</name>
<fsummary>Return the filter with the given Id</fsummary>

<v>FilterID = long()</v>
<v>Reply = Filter | {'EXCEPTION', #'CosNotifyFilter_FilterNotFound'{}}</v>
<v>Filter = #objref</v>
</type>
<desc>
<p>If the target object is associated with a <c>Filter</c> matching the given Id the
reference will be returned. If no such <c>Filter</c> is known by the target object
an exception is raised.</p>
</desc>
</func>
<func>
<name>get_all_filters(Object) -> FilterIDSeq</name>
<fsummary>Return a list of all filter Id:s associated with the target object</fsummary>

<v>Object = #objref</v>
<v>FilterIDSeq = [FilterID]</v>
<v>FilterID = long()</v>
</type>
<desc>
<p>Id's for all <c>Filter</c> objects associated with the target object is
returned by this operation.</p>

<func>
<name>remove_all_filters(Object) -> ok</name>
<fsummary>Remove all filters from the target object</fsummary>
<type>
<v>Object = #objref</v>
</type>
<desc>
<p>If we want to remove all <c>Filters</c> associated with the target object we can use this function.</p>
