static EngineManagement Apama.Engine.Api.ConnectToEngine	(	string	host,
		ushort	port
	)

static

This function attempts to establish a connection to an Engine. It returns an EngineManagement object that can be used to access the Engine.

Parameters

host	The hostname of the machine where the Engine is running on.
port	The port that the Engine is listening on for transport negotiations with the client.

Returns: An EngineManagement object if an Engine is located and a connection established. Call DisconnectFromEngine when finished with this object.

static EngineManagement Apama.Engine.Api.ConnectToEngine	(	string	host,
		ushort	port,
		bool	disconnectSlowReceiver
	)

static

This function attempts to establish a connection to an Engine. It returns an EngineManagement object that can be used to access the Engine.

Parameters

host	The hostname of the machine where the Engine is running on.
port	The port that the Engine is listening on for transport negotiations with the client.
disconnectSlowReceiver	Disconnect any receiver if it is slow, defaults to false

Returns: An EngineManagement object if an Engine is located and a connection established. Call DisconnectFromEngine when finished with this object.

static EngineManagement Apama.Engine.Api.ConnectToEngineMonitorOnly	(	string	host,
		ushort	port
	)

static

Attempt to establish a monitor-only connection to an Engine listening on the named host and port. If successful, the returned EngineManagement can be used for the ConnectEventConsumer(), GetStatus(), InspectEngine() and Ping() operations. All other operations will fail.

Parameters

host	The hostname of the machine where the Engine is running on.
port	The port that the Engine is listening on for transport negotiations with the client.

Returns: An EngineManagement object operating in monitor-only mode. Call DisconnectFromEngine when finished with this object.

static EngineManagement Apama.Engine.Api.ConnectToEngineReceiveOnly	(	string	host,
		ushort	port
	)

static

Attempt to establish a receive-only connection to an Engine listening on the named host and port. If successful, the returned EngineManagement can be used for the ConnectEventConsumer(), GetStatus(), InspectEngine() and Ping() operations. All other operations will fail.

Parameters

host	The hostname of the machine where the Engine is running on.
port	The port that the Engine is listening on for transport negotiations with the client.

Returns: An EngineManagement object operating in receive-only mode. Call DisconnectFromEngine when finished with this object.

static void Apama.Engine.Api.DisconnectFromEngine ( EngineManagement engineManagement )

static

Legacy method equivalent to EngineManagement.Dispose()

Deprecated - Use EngineManagement.Dispose() instead.

Parameters

engineManagement The Engine to disconnect from.

static void Apama.Engine.Api.EngineInit ( )

static

This method must be called when the client program is started. It initializes the library's state. Calling it more than once has no effect.

static void Apama.Engine.Api.EngineInit ( bool messaging )

static

This function must be called once per process first before any other Engine operations are carried out. It initializes the library's state. Calling it more than once has no effect.

Parameters

messaging Determines whether to initialise messaging transport

static void Apama.Engine.Api.EngineInit	(	string	name,
		bool	messaging
	)

static

This function must be called once per process first before any other Engine operations are carried out. It initializes the library's state. Calling it more than once has no effect.

Parameters

name	The name of the engine client
messaging	Determines whether to initialise messaging transport

static void Apama.Engine.Api.EngineShutdown ( )

static

This function must be called once per process before the application closes down. It ensures that communications are shutdown properly and state is cleaned up.

The upper .NET API layers (EngineClient, EventService and ScenarioService) use AppDomain.ProcessExit event handler to run shutdown and cleanup operations upon exiting the application. As described in http://msdn.microsoft.com/en-us/library/system.appdomain.processexit.aspx the total execution time of all ProcessExit event handlers is limited, just as the total execution time of all finalizers is limited at process shutdown. The default is three seconds.

static void Apama.Engine.Api.SetEngineParams ( [MarshalAs(UnmanagedType.LPWStr)] string arg0 )

static

Set custom parameters for this instance of the client library. Must be called before engineInit. The parameters are passed as a set of name, value pairs formatted as <name1>=<value1>;<name2=value2>; (i.e. equals sign between name and value, and semicolon separating the name value pairs).

The following parameters are defined so far.

ConfigFile - A filename from which to read a configuration file LogicalID - The logical id with which this component should be identified (a 64-bit integer)

Parameters

arg0	The paramters to set as a formatted string
