Detailed Description

A component which writes data reports to a tcp/ip socket.

It can serve different clients. It uses a ASCI-based protocol.

Usage

Authentication of the client:

The server accepts different kinds of commands. Before these commands are available for the client, the client has to authenticate itself.

Send:
```
"VERSION 1.0\n" 
```
Receive:
- if succesfull:
```
"101 OK\n" 
```
- if failed:
```
"106 not supported\n" 
```

Getting Help:

The client can get the available commands

Send:
```
"HELP\n" 
```

Receive:

         "Use HELP <command>\n
          CommandName1\n
          CommandName2\n
          ...
          CommandNameN\n."

and the syntax for each command.

Send:
```
"HELP CommandName\n" 
```

Receive:

         "Name: CommandName\n
          Usage: CommandName CommandSyntax\n"

Getting a list of available data:

The client can get the names of all the available data.

Send:
```
"HEADERS\n" 
```

Receive:

         "305 DataName1\n
          305 DataName2\n
          ...
          305 DataNameN\n
          306 End of list\n"

Subscribe to Data:

The client has to send the server the names of the available data he wants to get. Only the subscribed data will be send to the client.

Send:
```
"SUBSCRIBE DataNameX\n" 
```
Receive:
- if succesfull:
```
"302 DataNameX\n" 
```
- if failed:
```
"301 DataNameX\n" 
```

Unsubscribe to Data:

The client can cancel a subscription.

Send:
```
"UNSUBSCRIBE DataNameX\n" 
```
Receive:
- if succesfull:
```
"303 DataNameX\n" 
```
- if failed:
```
"304 DataNameX\n" 
```

Getting a list of the subscriptions:

The client can ask for the subscriptions he has made.

Send:
```
"SUBS\n" 
```

Receive:

         "305 DataNameX1\n
          305 DataNameX2\n
          ...
          305 DataNameXN\n
          306 End of list\n"

Start/stop streaming the data:

The client can start and stop the streaming of the subscribed data.

Send: -To start:
```
"SILENCE OFF\n" 
```
-To stop:
```
"SILENCE ON\n" 
```
Receive:
```
"107 SILENCE ON/OFF\n" 
```

Close the connection with the server:

The client can close the connection with the server.

Send:
```
"QUIT\n" 
```
or
```
"EXIT\n" 
```
Receive:
```
"104 Bye Bye\n" 
```

When an error occures:

When an error occurs because of wrong syntax the server will answer with an error message.

Send: wrong command syntax

Receive:

"102 Syntax: CommandNameX CommandSyntaxX\n"

The streaming data:

When the streaming is started the server will send the following message at each timeframe.

Receive:

         "201 framenr --- begin of frame\n
          202 DataNameX1\n
          205 DataValueX1\n
          202 DataNameX2\n
          205 DataValueX2\n
          ...
          202 DataNameXN\n
          205 DataValueXN\n
          203 framenr --- end of frame\n"

Member Typedef Documentation

typedef boost::tuple<std::string, RTT::base::DataSourceBase::shared_ptr, std::string,RTT::base::PropertyBase*,RTT::base::InputPortInterface*,bool,bool> DTupple [protected, inherited]

tuple that describes each sample.

Uses get<N>() to read it: @0 The qualified name of the data (componentname.portname) @1 The data source of the data. Always returns the last value. @2 A copy command to copy from this data source to another one @3 The target data source for the copy operation @4 The type of the data, "Data" (props and attrs) or "Port". @5 'newdata': The new data flag. Flags if the DataSource contains new data. @6 'tracked': True if this source may lead to additional data. If false, the source in itself will not cause to a re-scan. Used in copydata() to allow ports to be rescanned, while props and attrs never cause this (they always have newdata, but this is ignored).

Constructor & Destructor Documentation

TcpReporting ( std::string fr_name = "ReportingComponent" )

Create a reporting component which starts up a server.

Parameters:

fr_name	Name of the TCP reporting component.
port	Port to listen on.

Definition at line 214 of file TcpReporting.cpp.

Member Function Documentation

bool addMarshaller	(	RTT::marsh::MarshallInterface *	headerM,
		RTT::marsh::MarshallInterface *	bodyM
	)		`[inherited]`

Adds a Plugin to receive incomming data.

The marshallers become owned by this component.

Parameters:

header	A marshaller which writes out a header when this component is started. May be null (0).
body	A marshaller wich will get periodically a serialisation request to process incomming data. May be null(0).

example: addMarshaller( new HeaderMarshaller(), new ContentsMarshaller() );
