Function Details

parse_rosrpc_uri(uri)

source code

utility function for parsing ROS-RPC URIs

Parameters:

uri (str) - ROSRPC URI

Returns: (str, int)

address, port

Raises:

ParameterInvalid - if uri is not a valid ROSRPC URI

deprecated(func)

source code

This is a decorator which can be used to mark functions as deprecated. It will result in a warning being emmitted when the function is used.

get_ros_root(*args, **kwargs)

source code

Get the value of ROS_ROOT.

Parameters:

env (dict) - override environment dictionary
required - if True, fails with ROSException

Returns: str

Value of ROS_ROOT environment

Decorators:

@deprecated

Raises:

ROSException - if require is True and ROS_ROOT is not set

get_node_uri()

source code

Get this Node's URI.

Returns: str: this Node's XMLRPC URI

set_node_uri(uri)

source code

set the URI of the local node. This is an internal API method, it does not actually affect the XMLRPC URI of the Node.

configure_logging(node_name, level=20)

source code

Setup filesystem logging for this node

Parameters:

node_name - Node's name @type node_name str
level (int) - (optional) Python logging level (INFO, DEBUG, etc...). (Default: logging.INFO)

is_initialized()

source code

Get the initialization state of the local node. If True, node has been configured.

Returns: bool: True if local node initialized

set_initialized(initialized)

source code

set the initialization state of the local node

Parameters:

initialized (bool) - True if node initialized

is_shutdown()

source code

Returns: bool: True if shutdown flag has been set

is_shutdown_requested()

source code

is_shutdown_requested is a state that occurs just before is_shutdown. It is initiated when a shutdown requested is received and continues until client shutdown handlers have been called. After client shutdown handlers have been serviced, the is_shutdown state becomes true.

Returns: bool: True if shutdown has been requested (but possibly not yet initiated)

add_client_shutdown_hook(h)

source code

Add client method to invoke when system shuts down. Unlike add_shutdown_hook and add_preshutdown_hooks, these methods will be called before any rospy internal shutdown code.

Parameters:

h (fn(str)) - function that takes in a single string argument (shutdown reason)

add_preshutdown_hook(h)

source code

Add method to invoke when system shuts down. Unlike add_shutdown_hook, these methods will be called before any other shutdown hooks.

Parameters:

h (fn(str)) - function that takes in a single string argument (shutdown reason)

add_shutdown_hook(h)

source code

Add method to invoke when system shuts down.

Shutdown hooks are called in the order that they are registered. This is an internal API method that is used to cleanup. See the client on_shutdown() method if you wish to register client hooks.

Parameters:

h (fn(str)) - function that takes in a single string argument (shutdown reason)

signal_shutdown(reason)

source code

Initiates shutdown process by signaling objects waiting on _shutdown_lock. Shutdown and pre-shutdown hooks are invoked.

Parameters:

reason (str) - human-readable shutdown reason, if applicable

xmlrpcapi(uri)

source code

Returns: xmlrpclib.ServerProxy: instance for calling remote server or None if not a valid URI
