Functions

Public

Name Remarks Include Path Unreal Specifiers

bool CanGraphInterfaceBeSet ( const UPCGGraphInterface* GraphInterface
) const

 When setting a graph instance as a base to another graph instance, we need to make sure we don't find this graph in the graph hierarchy. PCGGraph.h  

void CopyParameterOverrides ( UPCGGraphInterface* InGraph
)

   PCGGraph.h  

FString ExportOverriddenPropertyIdsChangeForEditor ( const FProperty* InProperty,
bool bMarkAsOverridden,
bool& bIsDifferent
) const

 For properties to be propagated correctly, changes need to happen with ImportText. PCGGraph.h  

FString GetDefaultPropertyValueForEditor ( const FProperty* InProperty,
bool& bIsDifferent
) const

 Same thing for the default value reset, for properties to be propagated correctly, changes need to happen with ImportText. PCGGraph.h  

bool GraphAssetFilter ( const FAssetData& AssetData
) const

 Because subgraph nodes hold graph instances, delegation of the selection can't be done elsewhere, so this function gets called when the dialog is opened and will forward to the graph customization if filtering is applied. PCGGraph.h  

bool IsPropertyOverridden ( const FProperty* InProperty
) const
