UInterchangeBaseNodeContainer

The Interchange [UInterchangeBaseNode](API\Runtime\InterchangeCore\Nodes\UInterchangeBaseNode) graph is a format used to feed factories and writers when they import, reimport, and export an asset or scene.

Syntax

UCLASS (BlueprintType, MinimalAPI)  
class UInterchangeBaseNodeContainer : public UObject

Remarks

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.

Functions

  Type Name Description
Public function UFunction BlueprintCallable, Category FString Add a node to the container. The node is added into a TMap.
Public function Const bool

BreakableIterateNodeChildren ( const FString& NodeUniqueID,
TFunctionRef< bool(const UInterchangeBaseNode*)> IterationLambda
)

 Recursively traverse the hierarchy starting with the specified node unique ID.
Public function Const void

BreakableIterateNodes ( TFunctionRef< bool(const FString&, UInterchangeBaseNode*)> IterationLambda
)

 Unordered iteration of the all nodes, but can be stopped early by returning true.
Public function Const void

 Return all nodes that are of the ClassNode type.
Public function Const UFunction BlueprintCallable, Category void

GetRoots ( TArray< FString >& RootNodes
)

 Return all nodes that do not have any parent.
Public function Const UFunction BlueprintCallable, Category bool

IsNodeUidValid ( const FString& NodeUniqueID
