Examples of com.ibm.icu.text.UCharacterIterator.moveCodePointIndex()

com.ibm.icu.text.UCharacterIterator.moveCodePointIndex()
Moves the current position by the number of code points specified, either forward or backward depending on the sign of delta (positive or negative respectively). If the current index is at a trail surrogate then the first adjustment is by code unit, and the remaining adjustments are by code points. If the resulting index would be less than zero, the index is set to zero, and if the resulting index would be greater than limit, the index is set to limit. @param delta the number of code units to move the current index. @return the new index @exception IndexOutOfBoundsException is thrown if an invalid delta is supplied @stable ICU 2.4
