Syntax

[USTRUCT](Programming/UnrealArchitecture/Reference/Structs)()
struct FNiagaraUserRedirectionParameterStore : public FNiagaraParameterStore

Remarks

Extension of the base parameter store to allow the user in the editor to use variable names without the "User." namespace prefix. The names without the prefix just redirect to the original variables, it is just done for better usability.

Functions

	Name	Description
void	GetUserParameters ( TArray< FNiagaraVariable >& OutPar... )	Get the list of FNiagaraVariables that are exposed to the user.
bool	IsUserParameter ( const FNiagaraVariableBase& InVar )
void	MakeUserVariable ( FNiagaraVariableBase& InVar )	Turn the input NiagaraVariable into the User namespaced version if needed, independent of whether or not it is in a redirection table.
void	RecreateRedirections()
bool	RedirectUserVariable ( FNiagaraVariableBase& UserVar )	If necessary it will replace the supplied variable with the fully qualified namespace (User.) appropriate for a user variable.
bool	SerializeFromMismatchedTag ( const FPropertyTag& Tag, FStructuredArchive::FSlot Slot )	Used to upgrade a serialized FNiagaraParameterStore property to our own struct

Overridden from FNiagaraParameterStore

	Name	Description
bool	AddParameter ( const FNiagaraVariable& Param, bool bInitialize, bool bTriggerRebind, int32* OutOffset )	Adds the passed parameter to this store.
void	Empty ( bool bClearBindings )	Removes all parameters from this store and releases any data.
const int32 ...	FindParameterOffset ( const FNiagaraVariableBase& Parame..., bool IgnoreType )
void	InitFromSource ( const FNiagaraParameterStore* ..., bool bNotifyAsDirty )	Called to initially set up the parameter store to exactly match the input store (other than any bindings and the internal name of it).
bool	RemoveParameter ( const FNiagaraVariableBase& Param )	Removes the passed parameter if it exists in the store.
void	Reset ( bool bClearBindings )	Removes all parameters from this store but doesn't change memory allocations.
