unreal.InterchangeBaseNodeContainer
¶
- class unreal.InterchangeBaseNodeContainer(outer: Object | None = None, name: Name | str = 'None')¶
Bases:
Object
The Interchange UInterchangeBaseNode graph is a format used to feed factories and writers when they import, reimport, and export an asset or scene.
This container holds a flat list of all nodes that have been translated from the source data. Translators fill this container, and the import/export managers read it to execute the import/export process.
C++ Source:
Module: InterchangeCore
File: InterchangeBaseNodeContainer.h
Editor Properties: (see get_editor_property/set_editor_property)
nodes
(Map[str, InterchangeBaseNode]): [Read-Only] Flat List of the nodes. Since the nodes are variable size, we store a pointer.
- add_node(node) str ¶
Add a node to the container. The node is added into a TMap. return:: return the node unique ID of the added item. If the node already exist it will return the existing ID. Return InvalidNodeUid if the node cannot be added.
- Parameters:
node (InterchangeBaseNode) – a pointer on the node you want to add
- Return type:
- compute_children_cache() None ¶
Fill the cache of children UIDs to optimize the GetNodeChildrenUids call.
- get_factory_node(node_unique_id) InterchangeFactoryBaseNode ¶
Get a factory node pointer.
- Parameters:
node_unique_id (str) –
- Return type:
- get_node(node_unique_id) InterchangeBaseNode ¶
Get a node pointer. Once added to the container, nodes are considered const.
- Parameters:
node_unique_id (str) –
- Return type:
- get_node_children(node_unique_id, child_index) InterchangeBaseNode ¶
Get the nth const child of the node
- Parameters:
node_unique_id (str) –
child_index (int32) –
- Return type:
- get_node_children_count(node_unique_id) int32 ¶
Get the number of children the node has.
- Parameters:
node_unique_id (str) –
- Return type:
int32
- load_from_file(filename) None ¶
Serialize the node container from the specified file.
- Parameters:
filename (str) –
- replace_node(node_unique_id, new_node) None ¶
Replace Node
- Parameters:
node_unique_id (str) –
new_node (InterchangeFactoryBaseNode) –
