Instance Method


Invalidates the layout information for the glyphs mapped to the given range of characters.


- (void)invalidateLayoutForCharacterRange:(NSRange)charRange actualCharacterRange:(NSRangePointer)actualCharRange;



The range of characters to invalidate.


If not NULL, on output, the actual range invalidated after any necessary expansion.


This method has the same effect as invalidateLayoutForCharacterRange:isSoft:actualCharacterRange: with flag set to NO.

This method only invalidates information; it performs no glyph generation or layout. You should rarely need to invoke this method.
