Syntax

class UInterchangeFactoryBaseNode : public UInterchangeBaseNode

Remarks

This struct is used to store and retrieve key value attributes. The attributes are store in a generic FAttributeStorage which serialize the value in a TArray64 See UE::Interchange::EAttributeTypes to know the supported template types This is an abstract class. This is the base class of the interchange node graph format, all class in this format should derive from this class

Variables

  Type Name Description
Protected variable TMap< UClass *, TArray< UE::Interchange::FApplyAttributeToAsset > > ApplyCustomAttributeDelegates This array hold the delegate to apply the attribute that has to be set on an UObject
Protected variable UE::Interchange::TArrayAttributeHelper< FString > FactoryDependencies Those dependencies are use by the interchange parsing task to make sure the asset are created in the correct order.
Protected variable TMap< UClass *, TArray< UE::Interchange::FFillAttributeToAsset > > FillCustomAttributeDelegates

Public function Const void  
Public function bool

FillAttributeFromObject ( const FString& NodeAttributeKey,
UObject* Object,
const FName PropertyName
)

Public function bool

FillAttributeFromObject ( const FString& NodeAttributeKey,
UObject* Object,
const FName PropertyName
)

 Specialized version of FillAttributeFromObject for bools.
Public function Const bool Return the custom ReferenceObject.
Public function Const bool

GetCustomSubPath ( FString& AttributeValue
)

 Return the custom sub-path under PackageBasePath, where the assets will be created.
Public function Const void

GetFactoryDependencies ( TArray< FString >& OutDependencies
)

 This function allow to retrieve the dependency for this object.
Public function Const int32 This function allow to retrieve the number of factory dependencies for this object.
Public function Const void

GetFactoryDependency ( const int32 Index,
FString& OutDependency
)

 This function allow to retrieve one dependency for this object.
Public function Virtual Const UClass * Return the UClass of the object we represent so we can find factory/writer
Public function Const EReimportStrategyFlags Return the reimport strategy flags.
Public function bool

RemoveFactoryDependencyUid ( const FString& DependencyUid
)

 Remove one dependency from this object.
Public function bool

SetCustomReferenceObject ( const FSoftObjectPath& AttributeValue
)

 Set the custom ReferenceObject.
Public function bool

SetCustomSubPath ( const FString& AttributeValue
)

 Set the custom sub-path under PackageBasePath where the assets will be created.

Public function bool

SetReimportStrategyFlags ( const EReimportStrategyFlags& ReimportStrategyFlags
)

 Change the reimport strategy flags.
Public function bool Add the skip node attribute.
Public function Const bool Return whether or not an object should be created even if it has been deleted in the editor.
Public function Const bool Return true if this node should skip the factory import process, false otherwise.
Public function bool Disallow the creation of the unreal object if it has been previously deleted in the editor.
Public function bool Remove the skip node attribute. See ShouldSkipNodeImport for more documentation.
