Node ID

A node ID fits on 16 bits and is used to encode a node index. The zero ID is reserved as an invalid value, this means that the node index is 1-based.

Node IDs are assigned during compilation of an AnimNext graph to each node. The trait reader is then used to convert them into a shared offset within the graph.

Functions

Public

Name	Remarks	Include Path
FNodeID GetNextID()	Returns the next node ID If the current ID is invalid, the next is invalid as well Note that this function does not handle wrapping if more than 65536 IDs are used If wrapping occurs, the next ID returned will be invalid and all subsequent IDs will be invalid	TraitCore/NodeID.h
uint32 GetNodeIndex()	Returns the node index represented by this node ID If the node ID is invalid, the index returned is 0xFFFFFFFF	TraitCore/NodeID.h
bool IsValid()	Returns whether or not this ID is valid.	TraitCore/NodeID.h

Static

Name	Remarks	Include Path	Unreal Specifiers
static FNodeID FromRawValue ( uint32 InID )	Creates a node handle from a raw packed value.	TraitCore/NodeID.h
static FNodeID GetFirstID()	The first valid node ID.	TraitCore/NodeID.h

Operators

Name	Remarks	Include Path	Unreal Specifiers
bool operator!= ( const FNodeID RHS ) const		TraitCore/NodeID.h
bool operator== ( const FNodeID RHS ) const	Equality and inequality tests.	TraitCore/NodeID.h
