question: returns a new charsequence that is a subsequence of the string representation of this builder using a specific locale . the subsequence starts with the char value at the specified index and ends with the char value at index end - 1 . the length in chars of the returned sequence is end - start , so if start == end then an empty sequence is returned . concode_field_sep StringBuilder sb concode_elem_sep long serialVersionUID concode_elem_sep List<Message> messages concode_elem_sep Locale locale concode_field_sep Message toMessage concode_elem_sep int length concode_elem_sep int length concode_elem_sep String toString concode_elem_sep String toString concode_elem_sep MessageBuilder append concode_elem_sep MessageBuilder append concode_elem_sep MessageBuilder append concode_elem_sep MessageBuilder append concode_elem_sep MessageBuilder append concode_elem_sep MessageBuilder append concode_elem_sep char charAt concode_elem_sep char charAt
target: CharSequence function ( Locale arg0 , int arg1 , int arg2 ) { return toString ( arg0 ) . subSequence ( arg1 , arg2 ) ; }
