Name	Remarks	Include Path
FNiagaraCompileHashVisitorDebugInfo * AddDebugInfo()		NiagaraCompileHashVisitor.h
int32 RegisterReference ( const void* InObject )	Registers a pointer for later reference in the compile id in a deterministic manner.	NiagaraCompileHashVisitor.h
void ToDebugString ( const T* InData, uint64 InDataCount, FString& OutStr )		NiagaraCompileHashVisitor.h
bool UpdateArray ( const TCHAR* InDebugName, const T* InData, uint64 InDataCount )	Adds an array of POD (plain old data) values to the hash.	NiagaraCompileHashVisitor.h
bool UpdateName ( const TCHAR* InDebugName, FName InName )	Adds the string representation of an FName to the hash	NiagaraCompileHashVisitor.h
bool UpdatePOD ( const TCHAR* InDebugName, const T& InData )	Adds a single value of typed POD (plain old data) to the hash.	NiagaraCompileHashVisitor.h
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.	NiagaraCompileHashVisitor.h
bool UpdateShaderFile ( const TCHAR* ShaderFilePath )		NiagaraCompileHashVisitor.h
bool UpdateShaderParameters()		NiagaraCompileHashVisitor.h
bool UpdateString ( const TCHAR* InDebugName, FStringView InData )	Adds an string value to the hash.	NiagaraCompileHashVisitor.h
