A flow representation.
-
class
selinonlib.flow.
Flow
(name, **opts)[source]¶ Bases:
selinonlib.node.Node
Flow representation.
-
add_eager_failure
(node)[source]¶ Add a node to eager failure nodes listing.
Parameters: node – a node that should be marked as eager failure node
-
add_nowait_node
(node)[source]¶ Add edge to this flow, do not wait for node to finish.
Parameters: node – add a node that should be marked with nowait flag
-
all_destination_nodes
()[source]¶ Compute all destination nodes for this flow.
Returns: all destination nodes in flow, including failures
-
all_nodes_from
()[source]¶ Compute all nodes that are stated in ‘from’ in edges section for this flow.
Returns: all source nodes in flow, excluding failures
-
all_nodes_to
()[source]¶ Compute all nodes that are stated in ‘to’ in edges section for this flow.
Returns: all destination nodes in flow, excluding failures
-
all_source_nodes
()[source]¶ Compute all source nodes for this flow.
Returns: all source nodes in flow, including failures
-
all_used_nodes
()[source]¶ Get all used nodes in this flow, including failures.
Returns: all used nodes in flow
-
parse_definition
(flow_def, system)[source]¶ Parse flow definition (fill flow attributes) from a dictionary.
Parameters: - flow_def – dictionary containing flow definition
- system – system in which flow is defined
-
should_propagate_compound_failures
(dst_node_name)[source]¶ Check whether this flow should info about failures (in compound/flattered mode).
Parameters: dst_node_name – destination node to which configuration should be propagated Returns: True if should propagate_compound_failures
-
should_propagate_compound_finished
(dst_node_name)[source]¶ Check whether this flow should info about finished nodes (in compound/flattered mode).
Parameters: dst_node_name – destination node to which configuration should be propagated Returns: True if should propagate_compound_finished
-
should_propagate_failures
(dst_node_name)[source]¶ Check whether this flow should propagate info about failed nodes.
Parameters: dst_node_name – destination node to which configuration should be propagated Returns: True if should propagate_failures
-
should_propagate_finished
(dst_node_name)[source]¶ Check whether this flow should propagate info about finished nodes.
Parameters: dst_node_name – destination node to which configuration should be propagated Returns: True if should propagate_finished
-
should_propagate_node_args
(dst_node_name)[source]¶ Check whether this flow should propagate flow arguments.
Parameters: dst_node_name – destination node to which configuration should be propagated Returns: True if should propagate_node_args
