netunicorn.base.nodes.UncountableNodePool

class UncountableNodePool(node_template, soft_limit=None)

Bases: Nodes

Represents a pool of nodes that is not countable (i.e., contains possibly infinite amount of nodes, e.g. cloud provider).

In the current implementation cannot have Nodes as elements.

Parameters:

• node_template (List[Node]) – list of nodes that will be used as a template for generating new nodes

• soft_limit (Optional[float], default: None)

Attributes

soft_limit

Soft limit for nodes in the pool to prevent infinite loops or excessive node generation.

Methods

dispatch_and_deserialize	Deserializes a JSON representation of the object and returns an instance of the object.
filter	Returns a pool of nodes that match the given filter function.
from_json	Class-specific implementation of deserialization from JSON.
set_property	Sets a property for all nodes in the pool.
skip	Returns a pool of nodes consisting of the nodes after the first 'count' nodes.
take	Returns a sequence of nodes consisting of the first count nodes.

soft_limit

Soft limit for nodes in the pool to prevent infinite loops or excessive node generation.

__next__()

Generate and returns the next node in the pool.

Returns:

Node – next node

static dispatch_and_deserialize(data)

Deserializes a JSON representation of the object and returns an instance of the object.

Parameters:

data (NodesRepresentation) – JSON representation of the object

Returns:

Nodes – instance of the object

filter(function)

Returns a pool of nodes that match the given filter function.

Parameters:

function (Callable[[Node], bool]) – filter function returning True if the node should be included in the result

Returns:

UncountableNodePool – pool of nodes

take(count)

Returns a sequence of nodes consisting of the first count nodes.

Parameters:

count (int) – number of nodes to take

Returns:

Sequence[Node] – sequence of nodes

skip(count)

Returns a pool of nodes consisting of the nodes after the first ‘count’ nodes.

Parameters:

count (int) – number of nodes to skip

Returns:

UncountableNodePool – pool of nodes

classmethod from_json(data, metadata=None)

Class-specific implementation of deserialization from JSON.

Parameters:

• data (List[Union[NodeRepresentation, NodesRepresentation]]) – JSON representation of the object

• metadata (Optional[Any], default: None) – optional additional information for the pool instantiation

Returns:

UncountableNodePool – instance of the object

set_property(name, value)

Sets a property for all nodes in the pool.

Parameters:

• name (str) – name of the property

• value (Union[str, float, int, Set[str], None]) – property value

Returns:

UncountableNodePool – self
