appends a subsequence of the character sequence csq to the target . this method works the same way as writer.writer csq.subsequence start , end . tostring . if csq is null , then the specified subsequence of the string `` null '' will be written to the target . concode_field_sep String TOKEN_NULL concode_elem_sep Object lock concode_field_sep void flush concode_elem_sep boolean checkError concode_elem_sep void close concode_elem_sep void write concode_elem_sep void write concode_elem_sep void write concode_elem_sep void write concode_elem_sep void write
Writer function ( CharSequence arg0 , int arg1 , int arg2 ) { if ( null == arg0 ) { write ( TOKEN_NULL . substring ( arg1 , arg2 ) ) ; } else { write ( arg0 . subSequence ( arg1 , arg2 ) . toString ( ) ) ; } return this ; }
