Functions

 |
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, |
|
 |
bool | UpdateArray
(
const TCHAR* InDebugName, |
Adds an array of POD (plain old data) values to the hash. |
 |
bool | UpdateName
(
const TCHAR* InDebugName, |
Adds the string representation of an FName to the hash |
 |
bool | UpdatePOD
(
const TCHAR* InDebugName, |
Adds a single value of typed POD (plain old data) to the hash. |
 |
bool | UpdateReference
(
const TCHAR* InDebugName, |
We don't usually want to save GUID's or pointer values because they have nondeterministic values. |
 |
bool | UpdateShaderFile
(
const TCHAR* ShaderFilePath |

bool | ||
 |
bool | UpdateString
(
const TCHAR* InDebugName, |
Adds an string value to the hash. |
