## Detailed Description

The interface used by command parsers.

CommandParserInterface provides a set of functions and interfaces that plug into the ConsoleServer class. Each CommandParserInterface works at the same time as other interfaces in the system.

## Member Function Documentation

virtual const char* CommandParserInterface::GetName | ( | void |  | ) | const`[pure virtual]`

You are responsible for overriding this function and returning a static string, which will identifier your parser. This should return a static string

Returns:
  The name that you return.

Implemented in LogCommandParser, RakNetCommandParser, and RakNetTransportCommandParser.

void CommandParserInterface::OnNewIncomingConnection | ( | SystemAddress | systemAddress,
|  | TransportInterface * | transport |
| ) |  |  | `[virtual]`

A callback for when systemAddress has connected to us.

Parameters:

  `[in]` | systemAddress | The player that has connected.
  `[in]` | transport | The transport interface that sent us this information. Can be used to send messages to this or other players.

Reimplemented in LogCommandParser.

void CommandParserInterface::OnConnectionLost | ( | SystemAddress | systemAddress,
|  | TransportInterface * | transport |
| ) |  |  | `[virtual]`

A callback for when systemAddress has disconnected, either gracefully or forcefully

Parameters:

  `[in]` | systemAddress | The player that has disconnected.
  `[in]` | transport | The transport interface that sent us this information.

Reimplemented in LogCommandParser.

virtual void CommandParserInterface::SendHelp | ( | TransportInterface * | transport,
|  | SystemAddress | systemAddress |
| ) |  |  | `[pure virtual]`

A callback for when you are expected to send a brief description of your parser to systemAddress

Parameters:

  `[in]` | transport | The transport interface we can use to write to
  `[in]` | systemAddress | The player that requested help.

Implemented in LogCommandParser, RakNetCommandParser, and RakNetTransportCommandParser.

virtual bool CommandParserInterface::OnCommand | ( | const char * | command,
|  | unsigned | numParameters,
|  | char ** | parameterList,
|  | TransportInterface * | transport,
|  | SystemAddress | systemAddress,
|  | const char * | originalString |
| ) |  |  | `[pure virtual]`

Given command with parameters parameterList , do whatever processing you wish.

Parameters:

  `[in]` | command | The command to process
  `[in]` | numParameters | How many parameters were passed along with the command
  `[in]` | parameterList | The list of parameters. parameterList[0] is the first parameter and so on.
  `[in]` | transport | The transport interface we can use to write to
  `[in]` | systemAddress | The player that sent this command.
  `[in]` | originalString | The string that was actually sent over the network, in case you want to do your own parsing

Implemented in LogCommandParser, RakNetCommandParser, and RakNetTransportCommandParser.

void CommandParserInterface::OnTransportChange | ( | TransportInterface * | transport | ) | `[virtual]`

This is called every time transport interface is registered. If you want to save a copy of the TransportInterface pointer This is the place to do it

Parameters:

  `[in]` | transport | The new TransportInterface

Reimplemented in LogCommandParser.

void CommandParserInterface::RegisterCommand | ( | unsigned char | parameterCount,
|  | const char * | command,
|  | const char * | commandHelp |
| ) |  |  | `[protected, virtual]`

Registers a command.

Parameters:

  `[in]` | parameterCount | How many parameters your command requires. If you want to accept a variable number of commands, pass CommandParserInterface::VARIABLE_NUMBER_OF_PARAMETERS
  `[in]` | command | A pointer to a STATIC string that has your command. I keep a copy of the pointer here so don't deallocate the string.
  `[in]` | commandHelp | A pointer to a STATIC string that has the help information for your command. I keep a copy of the pointer here so don't deallocate the string.

void CommandParserInterface::ReturnResult | ( | bool | res,
|  | const char * | command,
|  | TransportInterface * | transport,
|  | SystemAddress | systemAddress |
| ) |  |  | `[protected, virtual]`

Just writes a string to the remote system based on the result ( res )of your operation This is not necessary to call, but makes it easier to return results of function calls

Parameters:

  `[in]` | res | The result to write
  `[in]` | command | The command that this result came from
  `[in]` | transport | The transport interface that will be written to
  `[in]` | systemAddress | The player this result will be sent to

void CommandParserInterface::ReturnResult | ( | const char * | command,
|  | TransportInterface * | transport,
|  | SystemAddress | systemAddress |
| ) |  |  | `[protected, virtual]`

Just writes a string to the remote system when you are calling a function that has no return value This is not necessary to call, but makes it easier to return results of function calls

Parameters:

  `[in]` | res | The result to write
  `[in]` | command | The command that this result came from
  `[in]` | transport | The transport interface that will be written to
  `[in]` | systemAddress | The player this result will be sent to

SystemAddress CommandParserInterface::IntegersToSystemAddress | ( | int | binaryAddress,
|  | int | port |
| ) |  |  | `[protected]`

Since there's no way to specify a systemAddress directly, the user needs to specify both the binary address and port. Given those parameters, this returns the corresponding SystemAddress

Parameters:

  `[in]` | binaryAddress | The binaryAddress portion of SystemAddress
  `[in]` | port | The port portion of SystemAddress
