Constructor & Destructor Documentation

def lama_interfaces.abstract_db_interface.AbstractDBInterface.__init__	(	self,
		interface_name,
		getter_srv_type,
		setter_srv_type,
		start = `False`
	)

Build the map interface and possibly start ROS services

Parameters
----------
- interface_name: string, name of the map interface.
- getter_srv_type: string, service message to write into the map.
- setter_srv_type: string, service message to read from the map.
- start: {True|False}, defaults to True. The ROS services for getter and
    setter will be started only if start is True. If start is False, the
    clients proxies will be None.

def lama_interfaces.abstract_db_interface.AbstractDBInterface._add_interface_description ( self ) [private]

Add the inteface description if not already existing

Add the inteface description with unconflicting
(interface_name / message_type / interface_type).

A ValueError is raised if a table with the same name (i.e. same
interface_name) but different message type and interface type already
exists.

def lama_interfaces.abstract_db_interface.AbstractDBInterface._get_last_modified ( self ) [private]

Return the date of last modification for this interface

Return a rospy.Time instance.

Definition at line 199 of file abstract_db_interface.py.

def lama_interfaces.abstract_db_interface.AbstractDBInterface._interface_table ( self ) [private]

Return the table for the type description (may already exists).

Return a table with columns ('interface_name', 'message_type',
interface_type, timestamp_secs, timestamp_nsecs). If the
table already exists, it will be returned.

def lama_interfaces.abstract_db_interface.AbstractDBInterface._set_timestamp	(	self,
		time
	)	`[private]`

Set the timestamp to the given time for this interface

Parameters
----------
- time: a rospy.Time instance.
