Question

我试图使用Esper EPL Online console并且我不知道如何在时间和事件序列中使用日期。例如，我有一个像这样定义的模式：

@Override
public View getView(int position, View convertView, ViewGroup parent) {
    int type = getItemViewType(position);
    final ItemDto dto = listStoreItemDto.get(position);
    if (convertView == null) {
        holder = new ViewHolder();
        switch (type) {
            case TYPE_IMAGE:
                convertView = mInflater.inflate(R.layout.listview_video, null);
                holder.vidImgAdapter = (ImageView)convertView.findViewById(R.id.vidImgAdapter);
                holder.vidImgPlayAdapter = (ImageView)convertView.findViewById(R.id.vidImgPlayAdapter);
                holder.vidNameAdapter = (TextViewVerbStyle)convertView.findViewById(R.id.vidNameAdapter);
                holder.vidDetailAdapter = (TextViewVerbStyle)convertView.findViewById(R.id.vidDetailAdapter);
                holder.linearAdpVideo = (LinearLayout)convertView.findViewById(R.id.linearAdpVideo);
                holder.tbAdpVideo = (ToggleButton)convertView.findViewById(R.id.tbAdpVideo);
                break;

我试图在时间和事件序列中添加一个事件，例如：

create schema EventCreated(
  source String,
  type String,
  time Date
);

但当然这不起作用。我尝试使用＆＃34; new Date（）＆＃34;或[com.espertech.esper.client.util.]DateTime.parseDefaultDate()但我无法使其发挥作用。

Answer 1

有一个＆＃34; eval＆＃34;用于评估EPL表达式。

StockTick={time=eval('com.espertech.esper.client.util.DateTime.parseDefaultDate("2016-10-07T10:00:00.000")')}

如果该工具只是接受字符串并使其成为日期，那就太好了。
