Public Member Functions | |
VertexNode () | |
Construct an empty program node with no command, no conditional branches and line number 0. | |
VertexNode (CommandInterface *cmd) | |
Construct a program node with given command, no conditional branches and line number 0. | |
VertexNode (const VertexNode &orig) | |
The copy constructor creates a shallow copy. | |
VertexNode | copy (std::map< const DataSourceBase *, DataSourceBase * > &rdss) const |
VertexNode & | operator= (const VertexNode &orig) |
~VertexNode () | |
Returns a special program node that contains no clauses and a special stopExecution command. | |
void | startExecution () |
This means that the execution engine has just started to execute this node, after some other node has sent it to this one. | |
bool | execute () |
Executes the command currently associated with this node. | |
bool | isValid () const |
Returns true if the node is in a valid state to be left. | |
CommandInterface * | setCommand (CommandInterface *c) |
Set the command associated with this program to the given command. | |
void | setLineNumber (int ln) |
Set line number of this program node to given line number. | |
CommandInterface * | getCommand () const |
Returns the command currently associated with this node. | |
int | getLineNumber () const |
Returns the program line number currently associated with this program node (default = zero). |
This class represents elements in a program tree.

RTT::VertexNode::~VertexNode | ( | ) |
Returns a special program node that contains no clauses and a special stopExecution command.
(all the leaves of a program tree are this type of program node.
proc | The engine executing this node (which will be stopped) |
CommandInterface* RTT::VertexNode::getCommand | ( | ) | const |
Returns the command currently associated with this node.
CommandInterface* RTT::VertexNode::setCommand | ( | CommandInterface * | c | ) |
Set the command associated with this program to the given command.
c | The new command. |
void RTT::VertexNode::setLineNumber | ( | int | ln | ) |
Set line number of this program node to given line number.
ln | The new line number for this node |
void RTT::VertexNode::startExecution | ( | ) |
This means that the execution engine has just started to execute this node, after some other node has sent it to this one.
If the node is simply executed again, because it returned itself from its execute() method, then this method will not be called. The reason this is here is because the node has to reset its termination conditions at this point. See the documentation of ConditionInterface::reset() for more information about this..
