new LiveView.Query(query, parameters, includeInternal)
Object that represents a LiveView query. This object is used as a parameter when calling
execute or subscribe. It stores the
query string (in parameterized format) as well as the parameters to apply when invoking execute or subscribe.
| Name | Type | Description |
|---|---|---|
query |
String | The optionally-parametrized query string |
parameters |
Object | optional A key-value map of parameters to use to compute the query string, if query is a parametrized string. Users are essentially free to define the key value used to identify a parameter as they wish. The query string is generated using regular expression substitution, so avoidance of regular expression special characters is recommended as it will likely cause unexpected behavior. The '@' character as a parameter prefix works well (e.g. {'@priceMin':100, '@lastUpdated':1415230518223}). |
includeInternal |
boolean | optional A flag indicating whether or not to include internal fields in (non-aggregate) query results. |
