Syntax

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

Remarks

Storage class containing actual runtime buffers to be used by the VM and the GPU. Is not the actual source for any parameter data, rather just the final place it's gathered from various other places ready for execution.

Variables

	Name	Description
uint8: 1	bInitialized
TArray< uint8 >	CachedScriptLiterals
uint32	PaddedParameterSize
TArray< FNiagar...	PaddingInfo
int32	ParameterSize	Size of the parameter data not including prev frame values or internal constants.

Constructors

	Name	Description
	FNiagaraScriptExecutionParameterStore()
	FNiagaraScriptExecutionParameterStore ( const FNiagaraParameterStore& Othe... )

Destructors

	Name	Description
	~FNiagaraScriptExecutionParameterStore()

Functions

	Name	Description
void	AddAlignmentPadding()
void	AddPaddedParamSize ( const FNiagaraTypeDefinition& InPa..., uint32 InOffset )
void	AddScriptParams ( UNiagaraScript* Script, ENiagaraSimTarget SimTarget, bool bTriggerRebind )
void	CoalescePaddingInfo()
void	InitFromOwningScript ( UNiagaraScript* Script, ENiagaraSimTarget SimTarget, bool bNotifyAsDirty )	TODO: These function can probably go away entirely when we replace the FNiagaraParameters and DataInterface info in the script with an FNiagaraParameterStore.

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.
bool	RemoveParameter ( const FNiagaraVariableBase& Param )	Removes the passed parameter if it exists in the store.
void	RenameParameter ( const FNiagaraVariableBase& Param, FName NewName )	Renames the passed parameter.
void	Reset ( bool bClearBindings )	Removes all parameters from this store but doesn't change memory allocations.

Operators

		Name	Description
	FNiagaraScri...	operator= ( const FNiagaraParameterStore& Othe... )
