	)	`[private]`

Definition at line 132 of file local_map_agent.py.

def lama_interfaces.local_map_agent.LocalMapAgent.action_callback	(	self,
		msg
	)

Callback of ActOnMap service

Return an instance of ActOnMap response.

Parameters
----------
- msg: an instance of ActOnMap request.

Definition at line 85 of file local_map_agent.py.

def lama_interfaces.local_map_agent.LocalMapAgent.assign_descriptor_to_lama_object	(	self,
		msg
	)

Add a descriptor to a vertex

Callback for ASSIGN_DESCRIPTOR_VERTEX and ASSIGN_DESCRIPTOR_EDGE.
Return an instance of ActOnMap response.

Parameters
----------
- msg: an instance of ActOnMap request.

Definition at line 177 of file local_map_agent.py.

def lama_interfaces.local_map_agent.LocalMapAgent.get_descriptor_links	(	self,
		msg
	)

Retrieve DescriptorLink associated with a LamaObject and an interface

Callback for GET_DESCRIPTOR_LINKS.
Return an instance of ActOnMap response.

Parameters
----------
- msg: an instance of ActOnMap request.

Definition at line 273 of file local_map_agent.py.

def lama_interfaces.local_map_agent.LocalMapAgent.get_edge_list	(	self,
		msg
	)

Retrieve edges from the database

Callback for GET_EDGE_LIST.
Retrieved all edges from the database that correspond to the search
criteria given in msg.object.
Search criteria are attributes with non-default values (0 or '').
Return an instance of ActOnMap response.

Parameters
----------
- msg: an instance of ActOnMap request.

Definition at line 255 of file local_map_agent.py.

def lama_interfaces.local_map_agent.LocalMapAgent.get_lama_object_list	(	self,
		lama_object
	)

Retrieve all elements that match the search criteria

Search criteria are attributes of lama_object with non-default values
(defaults are 0 or '').
Return a list of LamaObject, or an empty list of no LamaObject matches.

Parameters
----------
- lama_object: an instance of LamaObject

Definition at line 42 of file local_map_agent.py.

def lama_interfaces.local_map_agent.LocalMapAgent.get_neighbor_vertices	(	self,
		msg
	)

Retrieve all neighbor vertices from the database

Callback for GET_NEIGHBOR_VERTICES.
Return an instance of ActOnMap response.

Parameters
----------
- msg: an instance of ActOnMap request.

Definition at line 290 of file local_map_agent.py.

def lama_interfaces.local_map_agent.LocalMapAgent.get_outgoing_edges	(	self,
		msg
	)

Retrieve edges starting at a given vertex

Callback for GET_OUTGOING_EDGES.
Return an instance of ActOnMap response containing edges (instances
of LamaObject) starting at the given vertex.
This is syntactic sugar because the functionality can be obtained with
GET_EDGE_LIST.

Parameters
----------
- msg: an instance of ActOnMapRequest.

Definition at line 305 of file local_map_agent.py.

def lama_interfaces.local_map_agent.LocalMapAgent.get_vertex_list	(	self,
		msg
	)

Retrieve all vertices from the database

Callback for GET_VERTEX_LIST.
Return an instance of ActOnMap response.

Parameters
----------
- msg: an instance of ActOnMap request.

Definition at line 240 of file local_map_agent.py.

def lama_interfaces.local_map_agent.LocalMapAgent.pull_lama_object	(	self,
		msg
	)

Retrieve a LaMa object from the database

Callback for PULL_VERTEX and PULL_EDGE.
The object id is given in msg.object.id.
Return an instance of ActOnMap response. The field descriptor_links will
be filled with all DescriptorLink associated with this LamaObject.
An error is raised if more LaMa objects correspond to the search
criteria.

Parameters
----------
- msg: an instance of ActOnMap request.

Definition at line 156 of file local_map_agent.py.

def lama_interfaces.local_map_agent.LocalMapAgent.push_lama_object	(	self,
		msg
	)

Add a LaMa object to the database

Callback for PUSH_VERTEX and PUSH_EDGE.
Return an instance of ActOnMap response.

Parameters
----------
- msg: an instance of ActOnMap request.
