Functions

  Type Name Description
Protected function Virtual Const bool

CanIgnoreNode ( const UEdGraphNode* Node
)

 Can this node be ignored for further processing?
Protected function Const int32 Counts the number of incoming edges this node has (along all input pins)
Protected function Const void

CreateExecutionSchedule ( const TArray< UEdGraphNode* >& GraphNodes,
TArray< UEdGraphNode* >& LinearExecutionSchedule
)

 Performs a topological sort on the graph of nodes passed in (which is expected to form a DAG), scheduling them.
Protected function Const UEdGraphNode *

FindNodeByClass ( const UEdGraph* Graph,
TSubclassOf< UEdGraphNode > NodeClass,
bool bExpectedUnique
)

 Scans a graph for a node of the specified class.
Protected function Virtual Const bool Does this pin potentially participate in data dependencies?
Protected function Virtual void

PruneIsolatedNodes ( const TArray< UEdGraphNode* >& RootSet,
TArray< UEdGraphNode* >& GraphNodes
)

 Prunes any nodes that weren't visited from the graph, printing out a warning
Protected function Virtual Const bool Should this node be kept even if it's not reached?
Protected function Const bool Performs standard validation on the graph (outputs point to inputs, no more than one connection to each input, types match on both ends, etc...)
Protected function Virtual Const void

ValidateLink ( const UEdGraphPin* PinA,
const UEdGraphPin* PinB
)

 Validates that the interconnection between two pins is schema compatible
Protected function Virtual Const void

ValidateNode ( const UEdGraphNode* Node
)

 Validates that the node is schema compatible
Protected function Virtual Const void

ValidatePin ( const UEdGraphPin* Pin
)

 Validate that the wiring for a single pin is schema compatible
