CosTransactions_Resource(3erl)				     Erlang Module Definition				    CosTransactions_Resource(3erl)

NAME

       CosTransactions_Resource - This module implements the OMG CosTransactions::Resource interface.

DESCRIPTION

       To get access to the record definitions for the structures use:
       -include_lib("cosTransactions/include/CosTransactions.hrl").

EXPORTS

       commit(Resource) -> Return

	      Types  Resource = #objref
		     Return = ok | {'EXCEPTION', E}
		     E	= #'CosTransactions_NotPrepared'{} | #'CosTransactions_HeuristicRollback'{} | #'CosTransactions_HeuristicMixed'{} | #'Cos-
		     Transactions_HeuristicHazard'{}

	      This operation instructs the Resource to commit all changes made as a part of the transaction.

	      The Resource can raise:

		* Heuristic Exception - if a Heuristic decision is made which differ from the true outcome of the transaction. The  Resource  must
		  remember the Heuristic outcome until the forget operation is performed.

       commit_one_phase(Resource) -> Return

	      Types  Resource = #objref
		     Return = ok | {'EXCEPTION', E}
		     E = #'CosTransactions_HeuristicHazard'{} | #'CosTransactions_TransactionRolledBack'{}

	      If possible, the Resource should commit all changes made as part of the transaction, else it should raise the TRANSACTION_ROLLEDBACK
	      exception. This operation can only be used if the Resource is the only child of its parent.

       forget(Resource) -> Return

	      Types  Resource = #objref
		     Return = ok

	      This operation informs the Resource that it is safe to forget any Heuristic decisions and the knowledge of the transaction.

       prepare(Resource) -> Return

	      Types  Resource = #objref
		     Return = Vote | {'EXCEPTION', E}
		     Vote = 'VoteReadOnly' | 'VoteCommit' | 'VoteRollback'
		     E = #'CosTransactions_HeuristicMixed'{} | #'CosTransactions_HeuristicHazard'{}

	      This operation is invoked on the Resource to begin the two-phase commit protocol.

	      The Resource can reply:

		* 'VoteReadOnly' - if no persistent data has been modified by the transaction. The Resource can forget all knowledge of the trans-
		  action.

		* 'VoteCommit'	-  if  the Resource has been prepared and is able to write all the data needed to commit the transaction to stable
		  storage.

		* 'VoteRollback' - under any circumstances but must do so if none of the alternatives above are applicable.

		* Heuristic Exception - if a Heuristic decision is made which differ from the true outcome of the transaction. The  Resource  must
		  remember the Heuristic outcome until the forget operation is performed.

       rollback(Resource) -> Return

	      Types  Resource = #objref
		     Return = ok | {'EXCEPTION', E}
		     E = #'CosTransactions_HeuristicCommit'{} | #'CosTransactions_HeuristicMixed'{} | #'CosTransactions_HeuristicHazard'{}

	      This operation instructs the Resource to rollback all changes made as a part of the transaction.

	      The Resource can raise:

		* Heuristic  Exception	- if a Heuristic decision is made which differ from the true outcome of the transaction. The Resource must
		  remember the Heuristic outcome until the forget operation is performed.

CosNotifyChannelAdmin_ProxyPushSupplier(3erl)		     Erlang Module Definition		     CosNotifyChannelAdmin_ProxyPushSupplier(3erl)

NAME

       CosNotifyChannelAdmin_ProxyPushSupplier - This module implements the OMG  CosNotifyChannelAdmin::ProxyPushSupplier interface.

DESCRIPTION

       To get access to the record definitions for the structures use:
       -include_lib("cosNotification/include/*.hrl").

       This module also exports the functions described in:

	 * CosNotifyComm_NotifySubscribe

	 * CosNotification_QoSAdmin

	 * CosNotifyFilter_FilterAdmi

	 * CosNotifyChannelAdmin_ProxySupplier

EXPORTS

       connect_any_push_consumer(ProxyPushSupplier, PushConsumer) -> Reply

	      Types  ProxyPushSupplier = #objref
		     PushConsumer = #objref
		     Reply = ok | {'EXCEPTION', #'CosEventChannelAdmin_AlreadyConnected'{}} | {'EXCEPTION', #'CosEventChannelAdmin_TypeError'{}}

	      This operation connects a PushConsumer to the target object. If a connection already exists or the given client does not support the
	      operation push an exception, AlreadyConnected and TypeError respectively, is raised.

       suspend_connection(ProxyPushSupplier) -> Reply

	      Types  ProxyPushSupplier = #objref
		     Reply = ok | {'EXCEPTION', #'CosNotifyChannelAdmin_ConnectionAlreadyInactive'{}} | {'EXCEPTION', #'CosNotifyChannelAdmin_Not-
		     Connected'{}}

	      This operation suspends the connection with the client object. If the connection already is suspended or no client have been associ-
	      ated an exception is raised.

       resume_connection(ProxyPushSupplier) -> Reply

	      Types  ProxyPullConsumer = #objref
		     Reply = ok | {'EXCEPTION', #'CosNotifyChannelAdmin_ConnectionAlreadyInactive'{}} | {'EXCEPTION', #'CosNotifyChannelAdmin_Not-
		     Connected'{}}

	      If  a connection have been suspended earlier, calling this operation will resume the connection. If the connection already is active
	      or no client have been connected an exception is raised.

       disconnect_push_supplier(ProxyPushSupplier) -> ok

	      Types  ProxyPushSupplier = #objref

	      This operation cause the target object to close the connection and terminate.
