UKismetStringLibrary::CullArray

function Engine Blueprint Since unknown

#include "Kismet/KismetStringLibrary.h"

Access: public Specifiers: staticBlueprintPure

Description

Removes zero-length entries from an array of strings in place and returns the resulting element count.

Caveats & Gotchas

• InArray is a non-const reference and is modified directly — pass a copy if you need to keep the original array with empty entries intact.
• The SourceString parameter isn't actually used by the culling logic; it exists only because of the function's Blueprint node signature.

Signature

static int32 CullArray(const FString& SourceString, TArray<FString>& InArray)

Parameters

Name	Type	Description	Default
SourceString	const FString&	Unused input string parameter carried over from the node's original signature.	—
InArray	TArray<FString>&	The array to remove zero-length entries from, modified in place.	—

Return Type

int32

Example

Remove empty entries after ParseIntoArray C++

TArray<FString> Tokens = UKismetStringLibrary::ParseIntoArray(Input, TEXT(","), false);
const int32 Remaining = UKismetStringLibrary::CullArray(Input, Tokens);
