CosEventChannelAdmin_ProxyPullSupplier(3erl)		     Erlang Module Definition		      CosEventChannelAdmin_ProxyPullSupplier(3erl)

NAME

       CosEventChannelAdmin_ProxyPullSupplier  -  This module implements a ProxyPullSupplier interface which acts as a middleman between pull con-
       sumer and the event channel.

DESCRIPTION

       The ProxyPullSupplier interface defines the second step for connecting pull consumers to the event channel. A proxy supplier is similar	to
       a normal supplier, but includes an additional method for connecting a consumer to the proxy supplier.

       To get access to all definitions, e.g., exceptions, include necessary hrl files by using:
       -include_lib("cosEvent/include/*.hrl").

       Any object that possesses an object reference that supports the ProxyPullSupplier interface can perform the following operations:

EXPORTS

       connect_pull_consumer(Object, PullConsumer) -> Return

	      Types  Object = #objref
		     PullConsumer = #objref of PullConsumer type
		     Return = ok | {'EXCEPTION', #'CosEventChannelAdmin_AlreadyConnected'{}}

	      This operation connects PullConsumer object to the ProxyPullSupplier object. A nil object reference can be passed to this operation.
	      If so a channel cannot invoke the disconnect_pull_consumer operation on the consumer; the consumer  may  be  disconnected  from  the
	      channel  without	being  informed.  If  the  ProxyPullSupplier  is  already connected to a PullConsumer, then the CosEventChannelAd-
	      min_AlreadyConnected exception is raised.

       disconnect_pull_supplier(Object) -> Return

	      Types  Object = #objref
		     Return = ok

	      This operation disconnects proxy pull supplier from the event channel. It sends a notification about the loss of the  connection	to
	      the pull consumer attached to it, unless nil object reference was passed at the connection time.

       pull(Object) -> Return

	      Types  Object = #objref
		     Return = any

	      This  operation  blocks until the event data is available or the CosEventComm_Disconnected exception is raised. It returns the event
	      data to the consumer.

       try_pull(Object) -> Return

	      Types  Object = #objref
		     Return = {any, bool()}

	      This operation does not block: if the event data is available, it returns the event data and sets  the  data  availability  flag	to
	      true;  otherwise	it  returns a long with an undefined value and sets the data availability to false. If the event communication has
	      already been disconnected, the CosEventComm_Disconnected exception is raised.

CosNotifyFilter_FilterAdmin(3erl)			     Erlang Module Definition				 CosNotifyFilter_FilterAdmin(3erl)

NAME

       CosNotifyFilter_FilterAdmin - 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.
