+ <modulesummary>This module implements a ProxyPushConsumer interface which acts as a middleman between push supplier and the event channel.</modulesummary>
+ <description>
+ <p>The ProxyPushConsumer interface defines the second step for connecting push
+ suppliers to the event channel. A proxy consumer is similar to a normal consumer,
+ but includes an additional method for connecting a supplier to the proxy
+ consumer.</p>
+ <p>To get access to all definitions, e.g., exceptions,
+ include necessary <c><![CDATA[hrl]]></c> files by using:<br></br><c><![CDATA[-include_lib("cosEvent/include/*.hrl").]]></c></p>
+ <p>Any object that possesses an object reference that supports the ProxyPushConsumer
+ interface can perform the following operations:</p>
+ </description>
+ <funcs>
+ <func>
+ <name>connect_push_supplier(Object, PushSupplier) -> Return</name>
+ <fsummary>Connect the push supplier to the proxy push consumer</fsummary>
+ <type>
+ <v>Object = #objref</v>
+ <v>PushSupplier = #objref of PushSupplier type</v>
+ <v>Return = ok | {'EXCEPTION', #'CosEventChannelAdmin_AlreadyConnected'{}}</v>
+ </type>
+ <desc>
+ <p>This operation connects PushSupplier object to the ProxyPushConsumer object.
+ A nil object reference can be passed to this operation. If so a channel
+ cannot invoke the disconnect_push_supplier operation on the supplier;
+ the supplier may be disconnected from the channel without being
+ informed. If the ProxyPushConsumer is already connected to a
+ PushSupplier, then the <c><![CDATA[CosEventChannelAdmin_AlreadyConnected]]></c>
+ exception is raised.</p>
+ </desc>
+ </func>
+ <func>
+ <name>disconnect_push_consumer(Object) -> Return</name>
+ <fsummary>Disconnect the ProxyPushConsumer object from the event channel.</fsummary>
+ <type>
+ <v>Object = #objref</v>
+ <v>Return = ok</v>
+ </type>
+ <desc>
+ <p>This operation disconnects proxy push consumer from the event channel.
+ Sends a notification about the loss of the connection to the push supplier
+ attached to it, unless nil object reference was passed at the connection
+ time.</p>
+ </desc>
+ </func>
+ <func>
+ <name>push(Object, Data) -> Return</name>
+ <fsummary>Communicate event data to the consumers.</fsummary>
+ <type>
+ <v>Object = #objref</v>
+ <v>Data = any</v>
+ <v>Return = ok | {'EXCEPTION', #'CosEventComm_Disconnected'{}}</v>
+ </type>
+ <desc>
+ <p>This operation sends event data to all connected consumers via the
+ event channel. If the event communication has already been disconnected,
+ the <c><![CDATA[CosEventComm_Disconnected]]></c> is raised.</p>
+ </desc>
