struct FNiagaraCompileHashVisitor

Used to store the state of a graph when deciding if it has been dirtied for recompile.

Type	Name	Description
FSHA1 &	HashState
TArray< const void * >	ObjectList
TArray< FNiagaraCompileHashVisitorDebugInfo >	Values	Debug data about the compilation hash, including key value pairs to detect differences.

	Type	Name	Description
		FNiagaraCompileHashVisitor ( FSHA1& InHashState )

Type	Name	Description
FNiagaraCompileHashVisitorDebugInfo *	AddDebugInfo ()
int32	RegisterReference ( const void* InObject )	Registers a pointer for later reference in the compile id in a deterministic manner.
void	ToDebugString ( const T* InData, uint64 InDataCount, FString& OutStr )
bool	UpdateArray ( const TCHAR* InDebugName, const T* InData, uint64 InDataCount )	Adds an array of POD (plain old data) values to the hash.
bool	UpdateName ( const TCHAR* InDebugName, FName InName )	Adds the string representation of an FName to the hash
bool	UpdatePOD ( const TCHAR* InDebugName, const T& InData )	Adds a single value of typed POD (plain old data) to the hash.
bool	UpdateReference ( const TCHAR* InDebugName, const void* InObject )	We don't usually want to save GUID's or pointer values because they have nondeterministic values.
bool	UpdateShaderFile ( const TCHAR* ShaderFilePath )
bool	UpdateShaderParameters ()
bool	UpdateString ( const TCHAR* InDebugName, FStringView InData )	Adds an string value to the hash.
