Functions

	Name	Description
void	BindParameters ( FNiagaraDataInterfaceParametersCS&..., const FNiagaraDataInterfaceGPUParam..., const FShaderParameterMap& Paramet... )	Methods that operate on an instance of type FNiagaraDataInterfaceParametersCS*, created by the above CreateComputeParameters() method
FNiagaraData...	CreateComputeParameters()	Constructs the correct CS parameter type for this DI (if any).
const FTypeL...	GetComputeParametersTypeDesc()
bool	HasInternalAttributeReads ( const UNiagaraEmitter* OwnerEm..., const UNiagaraEmitter* Provide... )	Returns true if the DI (owned by OwnerEmitter) reads any attributes from the Provider emitter
