NAME

       cosEventApp - The main module of the cosEvent application.

DESCRIPTION

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

       This module contains the functions for starting and stopping the application.

EXPORTS

       install() -> Return

              Types:

                 Return = ok | {'EXCEPTION', E} | {'EXIT', R}

              This operation installs the cosEvent application.

       uninstall() -> Return

              Types:

                 Return = ok | {'EXCEPTION', E} | {'EXIT', R}

              This operation uninstalls the cosEvent application.

       start() -> Return

              Types:

                 Return = ok | {error, Reason}

              This operation starts the cosEvent application.

       stop() -> Return

              Types:

                 Return = ok | {error, Reason}

              This operation stops the cosEvent application.

       start_channel() -> Channel

              Types:

                 Channel = #objref

              This  operation  creates  a  new  instance  of  a  Event  Channel using the default
              settings.

       start_channel(Options) -> Channel

              Types:

                 Options = [Option]
                 Option = {pull_interval, Seconds} | {typecheck, Boolean} | {maxEvents,  Integer}
                 | {blocking, Boolean}
                 Channel = #objref

              This operation creates a new instance of a Event Channel

                * {pull_interval,  Seconds} - determine how often Proxy Pull Consumers will check
                  for new events with the client application. The default value is 20 seconds.

                * {typecheck, Boolean} - if this option is set to true the proxies will check  if
                  the supplied client object is of correct type. The default value is false.

                * {maxEvents,   Integer}   -   this   option   determine   how  many  events  the
                  ProxyPullSuppliers will store before discarding events. If the limit is reached
                  events will be discarded in any order. The default value is 300.

                * {blocking,  Boolean}  -  this option determine the behavior of the channel when
                  handling events internally. If set to true the risk of a single event  supplier
                  floods  the  system  is  reduced,  but the performance may also be reduced. The
                  default value is true.

       start_channel_link() -> Channel

              Types:

                 Channel = #objref

              This operation creates a new instance of a Event Channel, which is  linked  to  the
              invoking process, using the default settings.

       start_channel_link(Options) -> Channel

              Types:

                 Options = [Option]
                 Option  = {pull_interval, Seconds} | {typecheck, Boolean} | {maxEvents, Integer}
                 | {blocking, Boolean}
                 Channel = #objref

              This operation creates a new instance of a Event Channel, which is  linked  to  the
              invoking  process,  with settings defined by the given options. Allowed options are
              the same as for cosEventApp:start_channel/1.

       stop_channel(Channel) -> Reply

              Types:

                 Channel = #objref
                 Reply = ok | {'EXCEPTION', E}

              This operation stop the target event channel.
