Studio:Transport Server Component

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.

transport._TSEvents

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

Name	Type	Description
OnConnect()	Method/Event	Fired when the transport connection state changes from disconnected to connected.
OnDisconnect()	Method/Event	Fired when the transport connection state changes from connected to disconnected.
OnEvent(string message)	Method/Event	Fired when there is a reportable event in the transport communication.

transport.Connection

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

Name	Type	Description
ActiveTransport	Property, Object, Read-Only	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.
bool ConnectAsync(    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.
bool 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, bool, Read-only	Returns the current connection state.
Loopback	Property,	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.

Name	Type	Description
IsLoaded	Property, bool	TBD.
HRESULT Load(    BSTR FullPath,    bool stat)	Method	TBD.
Path	Property, string	TBD.
HRESULT Load(    bool stat)	Method	TBD.

transport.Connection.Loopback

This is the interface for loopback settings.

Name	Type	Description
Sent	Property, unsigned long Read-only	TBD.
DataErrors	Property, unsigned long Read-only	TBD.
TimeoutErrors	Property, unsigned long Read-only	TBD.
Interval	Property, unsigned long Read-only	TBD.
Timeout	Property, unsigned long Read-only	TBD.
HResult Start(bool* pVal)	Method	TBD.
HResult Stop(bool* pVal)	Method	TBD.

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.

Name	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.

Name	Type	Description
IBlocks	Collection	TBD.
SequenceErrors	Collection	TBD.
TargetResources	Collection	TBD.

transport.Connection.Statistics.IBlocks

This is the interface for IBlock settings.

Name	Type	Description
Sent	Property, unsigned long	TBD.
Received	Property, unsigned long	TBD.
HResult Reset()	Method	TBD.

transport.Connection.Statistics.SequenceErrors

This is the interface for sequence error settings.

Name	Type	Description
Host	Property, unsigned long	TBD.
Target	Property, unsigned long	TBD.
HResult Reset()	Method	TBD.
HResult Update()	Method	TBD.

transport.Connection.Statistics.TargetResources

This is the interface for the target resource settings

Name	Type	Description
MessageQueue	Property, unsigned long	TBD.
Subscribers	Property, unsigned long	TBD.
EmbeddedPointers	Property, unsigned long	TBD.
STIDs	Property, unsigned long	TBD.
SUIDs	Property, unsigned long	TBD.
SUIDOverrides	Property, unsigned long	TBD.
SUIDFilters	Property, unsigned long	TBD.
HResult Reset()	Method	TBD.
HResult Update()	Method	TBD.

transport.Connection.Transports

This is the collection of currently available transports.

Name	Type	Description
Count	Property, integer, Read-only	Gives the number of transport items in the collection.
Item(variant index)	Method	Returns the specified transport item. Index can be a zero-based integer value or a string representing the name of the transport. Each transport advertises a unique name via its API and that’s what we use as the string keys. As per our usual policy, out-of-range integer indices will generate exceptions and out-of-range string indices will return null.

transport.Connection.Transports.Item

This is the interface associated with each transport object.

Name	Type	Description
Active	Property, bool	Sets/gets the active status of the transport. Only one transport can be active at any given time, so setting this to true for a transport that is not already active will cause the current active transport to be disconnected. Setting this property to true when the item is already active is a no-op.
File	Property, string, Read-only	Gets the full file path and name for the corresponding transport DLL.
Name	Property, string, Read-only	Gets the name of the transport item.
Properties	Collection	Collection of properties

transport.Connection.Transports.Properties

This is the collection of properties for a given transport.

Name	Type	Description
Count	Property, integer, Read-only	Gives the number of properties in the collection.
Item(variant index)	Method	Returns the specified property item. Index can be a zero-based integer value or a string representing the name of the property. As per our usual policy, out-of-range integer indices will generate exceptions and out-of-range string indices will return null.

transport.Connection.Transports.Properties.Item

This is the interface for a specific transport property.

Name	Type	Description
AllowableValues	Property, string, Read-only	Gets a pipe-delimited string where each delimited value represents an allowable value for the property. Clients might use this to restrict or validate input.
Name	Property, string, Read-only	Gets the name of the property item.
Value	Property, string	Gets/sets the value of the property. When set, the validation method of the transport will be called. Any failures in validation will be returned as exceptions here.
