### MODULE SUMMARY

This module implements the OMG CosNotifyChannelAdmin::ConsumerAdmin interface.

### DESCRIPTION

To get access to the record definitions for the structures use:

### EXPORTS

_get_MyID(ConsumerAdmin) -> AdminID

Types:

ConsumerAdmin = #objref
AdminID = long()

The ID returned by the creating channel is equal to the value encapsulated by this readonly attribute.

_get_MyChannel(ConsumerAdmin) -> Channel

Types:

ConsumerAdmin = #objref
Channel = #objref

The creating channel's reference is maintained by this readonly attribute.

_get_MyOperator(ConsumerAdmin) -> OpType

Types:

ConsumerAdmin = #objref
OpType = 'AND_OP' | 'OR_OP'

When ConsumerAdmin's are created an operation type, i.e., 'AND_OP' or 'OR_OP', is supplied, which determines the semantics used by the target object concerning evaluation against any associated Filter objects.

_get_priority_filter(ConsumerAdmin) -> MappingFilter

Types:

ConsumerAdmin = MappingFilter = #objref

If set, this operation returns the associated priority MappingFilter, otherwise a NIL object reference is returned.

_set_priority_filter(ConsumerAdmin, MappingFilter) -> ok

Types:

ConsumerAdmin = MappingFilter = #objref

To associate a priority MappingFilter with the target object this operation must be used.

_get_lifetime_filter(ConsumerAdmin) -> MappingFilter

Types:

ConsumerAdmin = MappingFilter = #objref

Unless a lifetime MappingFilter have been associated with the target object a NIL object reference is returned by this operation.

_set_lifetime_filter(ConsumerAdmin, MappingFilter) -> ok

Types:

ConsumerAdmin = MappingFilter = #objref

This operation associate a lifetime MappingFilter with the target object.

_get_pull_suppliers(ConsumerAdmin) -> ProxyIDSeq

Types:

ConsumerAdmin = #objref
ProxyIDSeq = [ProxyID]
ProxyID = long()

This readonly attribute maintains the Id's for all PullProxies created by the target object and still alive.

_get_push_suppliers(ConsumerAdmin) -> ProxyIDSeq

Types:

ConsumerAdmin = #objref
ProxyIDSeq = [ProxyID]
ProxyID = long()

This attribute is similar to the _get_pull_suppliers attribute but maintains the Id's for all PushProxies created by the target object and still alive.

get_proxy_supplier(ConsumerAdmin, ProxyID) -> Reply

Types:

ConsumerAdmin = #objref
ProxyID = long()
Reply = Proxy | {'EXCEPTION', #'CosNotifyChannelAdmin_ProxyNotFound'{}}
Proxy = #objref

If a proxy with the given Id exists the reference to the object is returned, but if the object have terminated, or an incorrect Id is supplied, an exception is raised.

obtain_notification_pull_supplier(ConsumerAdmin, ConsumerType) -> Reply

Types:

ConsumerAdmin = #objref
ConsumerType = 'ANY_EVENT' | 'STRUCTURED_EVENT' | 'SEQUENCE_EVENT'
Reply = {Proxy, ProxyID}
Proxy = #objref
ProxyID = long()

Determined by the parameter ConsumerType, a proxy which will accept events of the defined type is created. Along with the object reference an Id is returned.

obtain_pull_supplier(ConsumerAdmin) -> Proxy

Types:

ConsumerAdmin = #objref
Proxy = #objref

This operation creates a new proxy which accepts #any{} events.

obtain_notification_push_supplier(ConsumerAdmin, ConsumerType) -> Reply

Types:

ConsumerAdmin = #objref
ConsumerType = 'ANY_EVENT' | 'STRUCTURED_EVENT' | 'SEQUENCE_EVENT'
Reply = {Proxy, ProxyID}
Proxy = #objref
ProxyID = long()

A proxy which accepts events of the type described by the parameter ConsumerType is created by this operation. A unique Id is returned as an out parameter.

obtain_push_supplier(ConsumerAdmin) -> Proxy

Types:

ConsumerAdmin = #objref
Proxy = #objref

The object created by this function is a proxy which accepts #any{} events.

destroy(ConsumerAdmin) -> ok

Types:

ConsumerAdmin = #objref

To terminate the target object this operation should be used. The associated Channel will be notified.
