public java.lang.String toString() {
#if ( $members.size() > 0 )
#set ( $i = 0 )
    return String.format("$classname{#foreach( $member in $members )$member.name=%s#if ( $i < $members.size() - 1 ), #end#set ( $i = $i + 1 )#end}"#foreach( $member in $members ),#if ( $member.objectArray )$member.accessor == null ? null : java.util.Arrays.asList($member.accessor)#else$member.accessor#end#end);
#else
