Funktionalität

Die Klasse CL_ICU_BREAKITERATOR bietet die Möglichkeit Breakiteratoren verschiedenen Typs zu erzeugen:

• CREATE_CHARACTER_INSTANCE,,Umbruchposition zwischen logischen Zeichen

• CREATE_WORD_INSTANCE,,,,Umbruchposition zwischen Wörtern

• CREATE_LINE_INSTANCE,,,,Mögliche Zeilenumbruchpositionen

• CREATE_SENTENCE_INSTANCE,,,,Umbruchposition zwischen Sätzen

Sprachspezifische Besonderheiten können durch die Angabe einer Locale berücksichtigt werden.
