toString Generator

public java.lang.String toString() {
#if ( $members.size() > 0 )
#set ( $i = 0 )
    return "{\"_class\":\"$classname\", " +
#foreach( $member in $members )
#set ( $i = $i + 1 )
#if ( $i == $members.size() )
#set ( $postfix = "+" )
#else
#set ( $postfix = "+ "", "" + " )
#end
#if ( $member.collection )
    "\"$member.name\":" + ($member.accessor == null ? "null" : java.util.Arrays.toString($member.accessor.toArray())) $postfix
#elseif ( $member.objectArray )
    "\"$member.name\":" + java.util.Arrays.toString($member.accessor) $postfix
#elseif ( $member.primitiveArray )
    "\"$member.name\":" + java.util.Arrays.toString($member.accessor) $postfix
#elseif ( $member.object )
    #if ($member.typeQualifiedName.contains("java.lang"))
    "\"$member.name\":" + ($member.accessor == null ? "null" : "\"" + $member.accessor + "\"" ) $postfix
    #else
    "\"$member.name\":" + ($member.accessor == null ? "null" : $member.accessor ) $postfix
    #end
#else
    "\"$member.name\":\"" + $member.accessor + "\"" $postfix
#end
#end
    "}";
#else
    return "{\"_class\":\"$classname\"}";
#end
}
