Syntax

template<typename ParentType>  
class TDynamicAttributeBase

Remarks

Base class for attributes that live on a dynamic mesh (or similar dynamic object)

Subclasses can override the On* functions to ensure the attribute remains up to date through changes to the dynamic object

Variables

	Type	Name	Description
	FName	Name	Optional FName identifier for this attribute set.

Destructors

	Type	Name	Description
		~TDynamicAttributeBase ()

Functions

Type	Name	Description
bool	CheckValidity ( bool bAllowNonmanifold, EValidityCheckFailMode FailMode )	Check validity of attribute
void	CompactInPlace ( const FCompactMaps& CompactMaps )	Compact the attribute in place
bool	CopyIn ( int RawID, void* Buffer, int BufferSize )	Generic function to copy data in to an attribute; it's up to the derived class to map RawID to chunks of attribute data
bool	CopyOut ( int RawID, void* Buffer, int BufferSize )	Generic function to copy data out of an attribute; it's up to the derived class to map RawID to chunks of attribute data
void	CopyParentClassData ( const TDynamicAttributeBase< ParentType >& Other )	Implementation of parent-class copy.
bool	CopyThroughMapping ( const TDynamicAttributeBase* Source, const FMeshIndexMappings& Mapping )	Copy data from a different attribute to this one, using the mesh index mapping to determine the correspondence
FName	GetName ()	Get optional identifier for this attribute set.
TDynamicAttributeBase *	MakeCompactCopy ( const FCompactMaps& CompactMaps, ParentType* ParentIn )	Allocate a new compact copy of the attribute layer, optionally with a different parent.
TDynamicAttributeBase *	MakeCopy ( ParentType* ParentIn )	Allocate a new copy of the attribute layer, optionally with a different parent
TDynamicAttributeBase *	MakeNew ( ParentType* ParentIn )	Allocate a new empty instance of the same type of attribute layer
TUniquePtr< TDynamicAttributeChangeBase< ParentType > >	NewBlankChange ()
void	OnCollapseEdge ( const DynamicMeshInfo::FEdgeCollapseInfo& CollapseInfo )	Update to reflect an edge collapse in the parent mesh
void	OnFlipEdge ( const DynamicMeshInfo::FEdgeFlipInfo& FlipInfo )	Update to reflect an edge flip in the parent mesh
void	OnMergeEdges ( const DynamicMeshInfo::FMergeEdgesInfo& MergeInfo )	Update to reflect an edge merge in the parent mesh
void	OnNewTriangle ( int TriangleID, bool bInserted )
void	OnNewVertex ( int VertexID, bool bInserted )
void	OnPokeTriangle ( const DynamicMeshInfo::FPokeTriangleInfo& PokeInfo )	Update to reflect a face poke in the parent mesh
void	OnRemoveTriangle ( int TriangleID )
void	OnRemoveVertex ( int VertexID )
void	OnReverseTriOrientation ( int TriangleID )
void	OnSplitEdge ( const DynamicMeshInfo::FEdgeSplitInfo& SplitInfo )	Update to reflect an edge split in the parent mesh
void	OnSplitVertex ( const DynamicMeshInfo::FVertexSplitInfo& SplitInfo, const TArrayView< const int >& TrianglesToUpdate )	Update to reflect an edge merge in the parent mesh
void	Reparent ( ParentType* NewParent )	Update any held pointer to the parent
void	Serialize ( FArchive& Ar )	Serialize to and from an archive.
void	SetName ( FName NameIn )	Set optional identifier for this attribute set.
