public class EventChannelFactoryImpl extends AbstractChannelFactory implements JacORBEventChannelFactoryOperations
EventChannelFactoryImpl
is a implementation of the
EventChannelFactory
interface which defines operations for creating and managing
new Notification Service style event channels. It supports a routine that creates new instances
of Notification Service event channels and assigns unique numeric identifiers to them. In
addition the EventChannelFactory
interface supports a routing, which can return
the unique identifiers assigned to all event channels created by a given instance of
EventChannelFactory
, and another routine which, given the unique identifier of an
event channel created by a target EventChannelFactory
instance, returns the object
reference of that event channel. config_, container_, logger_, thisRef_

public EventChannel create_channel(Property[] qualitiyOfServiceProperties, Property[] administrativeProperties, IntHolder channelIdentifier) throws UnsupportedAdmin, UnsupportedQoS
create_channel
operation is invoked to create a new instance of the
Notification Service style event channel. This operation accepts two input parameters. The
first input parameter is a list of name-value pairs, which specify the initial QoS property
settings for the new channel. The second input parameter is a list of name-value pairs, which
specify the initial administrative property settings for the new channel. EventChannel
Interface exists that can support all
of the requested administrative property settings, the UnsupportedAdmin
exception is raised This exception contains as data a sequence of data structures, each
identifies the name of an administrative property in the input list whose requested setting
could not be satisfied, along with an error code and a range of settings for the property
which could be satisfied. The meanings of the error codes that might be returned are
described in Notification Service Specification
Table 2-5 on page 2-46. create_channel
operation will
return a reference to a new Notification Service style event channel. In addition, the
operation assigns to this new event channel a numeric identifier, which is unique among all
event channels created by the target object. This numeric identifier is returned as an output
parameter.create_channel
