# invalidateLayout(forCharacterRange:actualCharacterRange:)

Invalidates the layout information for the glyphs that map to the specified character range.

## Declaration

```swift
func invalidateLayout(forCharacterRange charRange: NSRange, actualCharacterRange actualCharRange: NSRangePointer?)
```

## Parameters

- `charRange`: The range of characters to invalidate.
- `actualCharRange`: If not NULL, on output, the actual range invalidated after any necessary expansion.

## Discussion

Discussion This method has the same effect as invalidateLayout(forCharacterRange:isSoft:actualCharacterRange:) with flag set to false. This method only invalidates information; it performs no glyph generation or layout. You should rarely need to invoke this method.
