Parameters

parameter SETTINGS = DotNetServer:Basic,Port:Basic,AdditionalPaths,ConnectTimeout,-ArchiveIO;
Configurable settings for this operation.

Properties

property AdditionalPaths as %String (MAXLEN = 32000);
Comma-separated list of assembly files containing classes you are using via the .NET Gateway. Each path element should correspond to individual assembly DLL entry, fully qualified. Example: "C:\InterSystems\IRIS\Dev\dotnet\bin\DotNetGatewaySamples.dll".
Property methods: AdditionalPathsDisplayToLogical(), AdditionalPathsGet(), AdditionalPathsIsValid(), AdditionalPathsLogicalToDisplay(), AdditionalPathsLogicalToOdbc(), AdditionalPathsNormalize(), AdditionalPathsSet()
property ConnectTimeout as %Numeric (MINVAL = 0) [ InitialExpression = 5 ];
Timeout in seconds to connect to the .NET Gateway Server from InterSystems IRIS.
Property methods: ConnectTimeoutDisplayToLogical(), ConnectTimeoutGet(), ConnectTimeoutIsValid(), ConnectTimeoutLogicalToDisplay(), ConnectTimeoutNormalize(), ConnectTimeoutSet()
property DotNetServer as %String [ InitialExpression = "127.0.0.1" ];
IP address or name of the machine where the .NET Gateway Server executable is located.
Property methods: DotNetServerDisplayToLogical(), DotNetServerGet(), DotNetServerIsValid(), DotNetServerLogicalToDisplay(), DotNetServerLogicalToOdbc(), DotNetServerNormalize(), DotNetServerSet()
property Port as %Integer [ InitialExpression = "55000" ];
TCP port number for communication between the .NET Gateway Server and the proxy classes in InterSystems IRIS.
Property methods: PortDisplayToLogical(), PortGet(), PortIsValid(), PortLogicalToDisplay(), PortNormalize(), PortSet()

Methods

method CloseConnection() as %Status
Close the connection from the business operation to the Gateway Server.
method ConnectDNG(ByRef pGateway As %Net.Remote.Gateway, pTimeout As %Numeric) as %Status
This method is invoked from GetConnection() and will either start a new connection or attempt to restore a broken connection. It can be used in case there is a failure during communication with the .NET Gateway Server. A status is returned indicating success or failure of the [re]connection.
method GetConnection(ByRef pGateway As %Net.Remote.Gateway, pTimeout As %Numeric) as %Status
Ensure we have a valid .NET Gateway connection. If not, try to recover. This method returns a private gateway connection object to be used with the proxy classes.
Example: 
     Set tSC = ..GetConnection(.tGateway) 
     If $$$ISOK(tSC) { 
        // Start using the .NET Gateway connection object tGateway 
        ... 
     }
method OnInit() as %Status
This user callback method is called just after %OnNew() to initialize the connection among other things. If you need to override this code, invoke the method in the superclass or add to the original code.
method OnTearDown() as %Status
This user callback method is called just before %OnClose() to disconnect from the .NET gateway server. If you need to override this code, invoke the method in the superclass or add to the original code.
