returns a new charsequence that is a subsequence of thissequence starting with the char value at the specified index.this provides the charsequence equivalent to string #substring int . the length in char of the returned sequence is length - start , so if start == end then an empty sequence is returned . concode_field_sep PlaceHolder placeHolder concode_field_sep int lastIndexOf concode_elem_sep int lastIndexOf concode_elem_sep char[] toCharArray concode_elem_sep boolean regionMatches concode_elem_sep int indexOf concode_elem_sep int indexOf
CharSequence function ( CharSequence arg0 , int arg1 ) { return arg0 == null ? null : arg0 . subSequence ( arg1 , arg0 . length ( ) ) ; }
