FName::DisplayHash

function Core Since 4.0

#include "UObject/NameTypes.h"

Access: public Specifiers: static

Description

Dumps name-table hash bucket statistics to an output device. Useful for diagnosing hash collision rates or verifying that Reserve() pre-allocation was sized appropriately.

Caveats & Gotchas

• This is a diagnostic utility only — it has no side effects on the name table and should never be left in production code due to the volume of output it generates.
• The output format is undocumented and implementation-defined; it has changed across engine versions and should not be parsed programmatically.
