class PointValueParser extends BaseValueParser {

async setValue(value) {
|
||
if (Array.isArray(value)) {
|
||
this.value = value;
|
||
} else if (typeof value === 'string') {
|
||
this.value = value.split(',');
|
||
} else {
|
||
this.errors.push('Value invalid');
|
||
}
|
||
}
|
||
}
|
||
|
||
const db = new Database();
|
||
|
||
// type=point 的字段导入时，将通过 PointValueParser 解析数据
|
||
db.registerFieldValueParsers({
|
||
point: PointValueParser,
|
||

```
