Public Member Functions

 CommandDispatch (CommandProcessor *p, CommandInterface *c, ConditionInterface *cn)
 Create a command to dispatch another command c to a CommandProcessor p.
 ~CommandDispatch ()
 Be sure only to delete this command if the target processor is not processing the encapsulated command.
void readArguments ()
bool ready () const
 The command's effect is done.
bool execute ()
bool dispatch ()
 Dispatch a command.
void reset ()
 After reset(), another attempt to dispatch the command will be made upon execute().
bool sent () const
 Returns true if the command was sent to the CommandProcessor.
bool accepted () const
 Returns true if the command was accepted when sent to the CommandProcessor.
bool executed () const
 Returns true if the command was executed by the CommandProcessor.
bool valid () const
 Returns true if the command was valid, i.e.
bool done () const
 Evaluate if the command is done.

Detailed Description

Dispatch a CommandInterface to a CommandProcessor.

The execute() method will return false from the moment on that the dispatched command failed. Hence, this execute() must not wrapped in an AsyncCommandDecorator, but directly executed by the caller.

Deprecated:
This class is nowhere used and to low level for users.

Member Enumeration Documentation

The status progressions of a Dispatchable Command.

The order of these enums is important and should not be altered.

Enumerator:
Ready 

The command is not yet initialised.

Sent 

The command is ready for execution.

NotAccepted 

The command has been sent/dispatched to the CommandProcessor.

Accepted 

The command was not accepted by the CommandProcessor.

Executed 

The command was accepted by the CommandProcessor.

NotValid 

The command was executed by the CommandProcessor.

Valid 

The command's arguments were found to be invalid.

Done 

The command's arguments were valid.

Definition at line 65 of file DispatchInterface.hpp.


Member Function Documentation

bool RTT::CommandDispatch::accepted (  )  const [virtual]

Returns true if the command was accepted when sent to the CommandProcessor.

A Command is accepted when the CommandProcessor was running and its queue was not full.

Implements RTT::DispatchInterface.

bool RTT::CommandDispatch::dispatch (  )  [virtual]

Dispatch a command.

If it is not accepted, fail, if it is accepted, return the dispatched command's result status.

Implements RTT::DispatchInterface.

bool RTT::CommandDispatch::done (  )  const [virtual]

Evaluate if the command is done.

Return values:
true if accepted(), valid() was true and the completion condition was true as well.
false otherwise.

Implements RTT::DispatchInterface.

bool RTT::CommandDispatch::executed (  )  const [virtual]

Returns true if the command was executed by the CommandProcessor.

When executed() is true, you can check its result().

Implements RTT::DispatchInterface.

bool RTT::CommandDispatch::ready (  )  const [virtual]

The command's effect is done.

Returns true if the command is ready for dispatch. If ready() returns true, dispatch() can be safely called, otherwise, dispatch() will fail.

Implements RTT::DispatchInterface.

bool RTT::CommandDispatch::sent (  )  const [virtual]

Returns true if the command was sent to the CommandProcessor.

You can use this flag to check whether execute() was invoked.

Implements RTT::DispatchInterface.

bool RTT::CommandDispatch::valid (  )  const [virtual]

Returns true if the command was valid, i.e.

the command itself was executed and returned true.

Implements RTT::DispatchInterface.
