UKismetStringLibrary::IsEmpty
#include "Kismet/KismetStringLibrary.h"
Access: public
Specifiers: staticBlueprintPure
Description
Returns true if the string is empty (zero length).
Caveats & Gotchas
- • A string containing only whitespace (e.g. " ") is not considered empty; Trim it first if whitespace-only strings should count as empty.
- • Equivalent to, but more readable in a graph than, checking Len(InString) == 0.
