__init__(model: GraphModel, root)

class EmptyPort(parent: Union[InputNode, OutputNode])

Bases: object

Is used by the model for an empty port

static get_type_name() → str

The string type that goes the source model abd view

class InputNode(model: GraphModel, source)

Bases: object

Is used by the model for the input node. This node represents input ports of the compound node and it’s placed to the subnetwork of the compound.

static get_type_name() → str

The string type that goes the source model and view

property ports: Optional[List[Any]]

The list of ports of this node. It only has input ports from the compound node.

class MagicWrapperMeta(name, bases, dct)

Bases: type

Python always looks in the class (and parent classes) __dict__ for magic methods and __getattr__ doesn’t work, but since we want to override them, we need to use this trick with proxy property.

It makes the class looking like the source object.

See https://stackoverflow.com/questions/9057669 for details.

class OutputNode(model: GraphModel, source)

Bases: object

Is used by the model for the ouput node. This node represents output ports of the comound node and it’s placed to the subnetwork of the compound.

static get_type_name() → str

The string type that goes the source model and view

property ports: Optional[List[Any]]

The list of ports of this node. It only has output ports from the compound node.

can_connect(source: Any, target: Any)

Return if it’s possible to connect source to target

subscribe_item_changed(fn)
