question: sets a new value instance overwriting the old value which is returned . you may use null . but you will get it back next call ! concode_field_sep V m_key concode_elem_sep K m_value concode_field_sep V getKey concode_elem_sep K getValue concode_elem_sep int hashCode concode_elem_sep boolean equals
target: K function ( final K arg0 ) { final K loc0 = this . m_value ; this . m_value = arg0 ; return loc0 ; }
