Detailed Description

This class wraps the implementation of the runCommand service.

This takes as input a ROS node handle and do not handle the callback so that the service behavior can be controlled from the outside.

◆ run_python_command_callback_t

typedef boost::function<bool(dynamic_graph_manager::RunCommand::Request&, dynamic_graph_manager::RunCommand::Response&)> dynamic_graph::RosPythonInterpreter::run_python_command_callback_t

run_python_command_callback_t define a boost::function to be used as callback to the ros::service.

The first argument of "runCommandCallback" (const std::string & command) is bound to (dynamic_graph_manager::RunCommand::Request). And the second argument (std::string &result) is bound to (dynamic_graph_manager::RunCommand::Response)

◆ run_python_file_callback_t

typedef boost::function<bool( dynamic_graph_manager::RunPythonFile::Request&, dynamic_graph_manager::RunPythonFile::Response&)> dynamic_graph::RosPythonInterpreter::run_python_file_callback_t

run_python_file_callback_t define a boost::function to be used as callback to the ros::service.

The first argument of "runPythonFileCallback" (std::string ifilename) is bound to (dynamic_graph_manager::RunCommand::Request). And a fake second argument is simulated in (dynamic_graph_manager::RunCommand::Response)

Constructor & Destructor Documentation

◆ RosPythonInterpreter()

dynamic_graph::RosPythonInterpreter::RosPythonInterpreter ( ros::NodeHandle & node_handle )

explicit

RosPythonInterpreter is the unique constructor of the class.

Parameters

node_handle is the ros::nodeHandle used to advertize the ros::services

Member Function Documentation

◆ run_python_command()

void dynamic_graph::RosPythonInterpreter::run_python_command	(	const std::string &	command,
		std::string &	result,
		std::string &	out,
		std::string &	err
	)

run_python_command used the python interpreter to execute the input command

Parameters

[in]	command	is the user input string command.
[out]	result	is the numerical result of the operation done.
[out]	out	is the string representation of the results.
[out]	err	is the output error string from python.

◆ run_python_file()

void dynamic_graph::RosPythonInterpreter::run_python_file	(	const std::string	ifilename,
		std::string &	standard_error
	)

run_python_file executes the input scripts in the python interpreter

Parameters

ifilename is the path to the script to execute

◆ runCommandCallback()

bool dynamic_graph::RosPythonInterpreter::runCommandCallback	(	dynamic_graph_manager::RunCommand::Request &	req,
		dynamic_graph_manager::RunCommand::Response &	res
	)

protected

runCommandCallback is the "run_python_command" ros service callback function.

Parameters

req	is the request. it is defined as a string in the RunCommand.msg
res	is the request. it is defined as a string in the RunCommand.msg

Returns: true

◆ runPythonFileCallback()

bool dynamic_graph::RosPythonInterpreter::runPythonFileCallback	(	dynamic_graph_manager::RunPythonFile::Request &	req,
		dynamic_graph_manager::RunPythonFile::Response &	res
	)

protected

runCommandCallback is the "run_python_script" ros service callback function.

Parameters

req	is the request. it is defined as a string in the RunCommand.msg
res	is the request. it is defined as a string in the RunCommand.msg

Returns: true
