FSoftObjectPath::AppendString

function CoreUObject Since 5.0

#include "UObject/SoftObjectPath.h"

Access: public

Description

Appends the full path string representation to an existing FString or string builder without allocating a new string. Prefer this over ToString() when building composite strings.

Caveats & Gotchas

• The FString overload appends to an already-allocated FString. The FStringBuilderBase and FUtf8StringBuilderBase overloads use the more efficient TStringBuilder path — prefer those in performance-sensitive code.
• For a null path, this appends nothing. The caller cannot distinguish a null path from an empty-string path by checking the builder's length before and after the call.

Signature

COREUOBJECT_API void AppendString(FString& Builder) const;
