The Transport Server

The Transport Server fields client requests to a target. The client communicates to the Transport Server. The Transport Server communicates to the target runtime of a target.

To access the transport server, a client first registers with to it using a process id (PID). This is done transparently for script clients using the script wrapper named STRIDE.transport.

Automation API

transport._TSEvents

This is an outgoing connection point interface that is optionally implemented by clients that wish to be notified of connection related events.

Member
 Type
 Description
HRESULT OnConnect (void) Method Event method fired when the transport connection state changes from disconnected to connected.
HRESULT OnDisconnect (void) Method Event method fired when the transport connection state changes from connected to disconnected.
HRESULT OnEvent (
   TSEventType type,
   TSEventLevel level,
   String message
) 		Method Event method fired when there is a reportable event in the transport communication.


transport.Connection

This is the root object for all connection-related functionality.

Member
 Type
 Description
ActiveTransport Object Returns the current active transport object or null if none is active.
bool Connect (
   int timeout [optional],
   bool* stat
) 		Method Attempts to create a runtime connection to a target using the active transport. The timeout value (in milliseconds) is passed to the runtime connection request and it fails if timeout is exceeded. Default timeout is 5 seconds (5000). Returns true if connection succeeded, false if either the transport or runtime connection failed.
boolConnectAsync(
   bool monitor[optional],
   int transportTimeout[optional],
   int runtimeTimeout,
    bool* stat
) 		Method Makes an asynchronous connection request. A background thread is started to attempt to establish the connection. If monitor is true, the thread will run continuously and attempt to reconnect whenever the connection is lost. If monitor is false (the default) the background thread will exit once a connection is initially established.
Database Object Database settings.
bool Disconnect (
   bool* stat
) 		Method Attempts to disconnect the runtime and the transport from the target. Returns true if successfully disconnected.
bool DisconnectAsync (
   bool* stat
) 		Method Initiates the request to disconnect from the target, but does not wait fo an acknowledgement of the disconnect request from runtime. Returns true if disconnect request initiated.
IBlockDataDump Property,
bool 		Turns IBlock dumps on or off. Default is off. If enabled, all IBlocks that are sent and received will be dumped to the STRIDE application log and to a predefined tracepoint.
IsConnected Property,
Read-only,
bool 		Returns the current connection state.
Loopback Object  Loopback settings.
Statistics Object Statistics settings.
TargetRuntimeVersion Property,
string 		Returns the runtime version string.
Ping Object Ping settings.
Transports Collection Collection of transports.
TransportsLocation Property,
string 		Sets/gets the current directory for transport DLLs. Changing this value will immediately change the values in the Transports collection and will cause the current connection (if any) to be closed.
TransportDataDump Property,
bool 		Turns raw data dumps on or off. Default is off. If enabled, all SLAP messages that are sent and received by the transport will be dumped to the STRIDE application log and to a predefined tracepoint.


transport.Connection.Database

This is the interface for database settings.

Member
 Type
 Description
IsLoaded Property,
Read-only,
bool 		Returns true if the database is loaded.
HRESULTLoad (
   String FullPath,
   bool stat
) 		Method Loads the database.
Path  Property,
Read-only,
String 		Returns the path to the database.
HRESULTUnload (
   bool stat
) 		Method Unloads the database.


transport.Connection.Loopback

This is the interface for loopback settings.

Member
 Type
 Description
Sent Property,
Read-only,
unsigned long 		Contains the number of loopbacks attempted.
DataErrors Property,
Read-only,
unsigned long 		Contains the number of data errors.
TimeoutErrors Property,
Read-only,
unsigned long 		Contains the number of timeout errors.
Interval Property,
unsigned long 		The interval value in milliseconds.
Timeout Property,
unsigned long 		The timeout value in milliseconds.
HRESULTStart(
   bool* pVal
) 		Method Start the loopback processing.
HRESULTStop(
   bool* pVal
) 		Method Stops the loopback processing.


transport.Connection.Ping

This is the interface for ping settings. All ping settings are automatically persisted in the registry and restored when the transport server is instantiated.

Member
 Type
 Description
Enabled Property,
bool 		Turns the runtime ping messages on or off. This setting is persisted and restored automatically.
Interval Property,
integer 		Sets/gets the time interval between ping messages, in milliseconds.
RetryCount Property,
integer 		Sets/gets the number of allowable ping failures. Once this number if exceeded, the connection will be closed automatically.
Timeout Property,
integer 		Sets/gets the timeout value for the ping message in milliseconds. If a response is not received within this time, the ping fails.


transport.Connection.Statistics

This is the interface for statistic settings.

Member
 Type
 Description
IBlocks Collection Collection of IBlock statistics.
SequenceErrors Collection Collection of Sequence Errors statistics.
TargetResources Collection Collection of Target Resource statistics.


transport.Connection.Statistics.IBlocks

This is the interface for IBlock settings.

Member
 Type
 Description
Sent Property,
Read-only,
unsigned long 		The number of IBlocks sent.
Received Property,
Read-only,
unsigned long 		The number of IBlocks received.
HRESULT Reset (void) Method Resets the counts to zero.

Name Property,
Read-only,
