classmethod evaluate_dataflow(dataflow, asset_to_update) → bool

s Evaluate a dataflow for a sepcific asset This will evaluate all the terminal nodes and generate any dependent asset if necessary This is synchronous operation, so large dataflow may block the game thread for a while when calling it

Parameters:

• dataflow (Dataflow) – Dataflow asset to evaluate

• asset_to_update (Object) – Asset to update from the Dataflow ( if a terminal exists for this type of asset )

Returns:

true if the evaluate executed with no errors

Return type:

bool

classmethod evaluate_terminal_node_by_name(dataflow, terminal_node_name, result_asset) → None

Find a specific terminal node by name evaluate it using a specific UObject

Parameters:

• dataflow (Dataflow)

• terminal_node_name (Name)

• result_asset (Object)

classmethod get_dataflow_variable_list(asset) → Array[DataflowVariable]

Get Dataflow Variable List

Parameters:

asset (Object)

Return type:

Array[DataflowVariable]
