object Windows

Builders for windows used when expressing windowed computations. There are two types of windows: documents and range.

Bounded and half-bounded windows require sorting. Window bounds are inclusive and the lower bound must always be less than or equal to the upper bound. The following type-specific rules are applied to windows:

  • documents
    • bounds
      • 0 refers to the current document and is functionally equivalent to CURRENT;
      • a negative value refers to documents preceding the current one;
      • a positive value refers to documents following the current one;
  • range
    • sortBy
      • must contain exactly one field;
      • must specify the ascending sort order;
      • the sortBy field must be of either a numeric BSON type (see the $isNumber aggregation pipeline stage) or the BSON Date type if time bounds are used;
    • bounds
      • if numeric, i.e., not com.mongodb.client.model.Windows.Bound, then the bound is calculated by adding the value to the value of the sortBy field in the current document;
      • if CURRENT, then the bound is determined by the current document and not the current value of the sortBy field;
      • time bounds require specifying a time unit and are added as per the $dateAdd/$dateSubtract aggregation pipeline stage specification.

  18. def of(window: Bson): Window

    Creates a window from Bson in situations when there is no builder method that better satisfies your needs.

    Creates a window from Bson in situations when there is no builder method that better satisfies your needs. This method cannot be used to validate the syntax.

    Example
    The following code creates two functionally identical windows, though they may not be equal.

    val pastWeek1: Window = Windows.timeRange(-1, MongoTimeUnit.WEEK, Windows.Bound.CURRENT)
val pastWeek2: Window = Windows.of(
    Document("range" -> BsonArray(-1, "current"),
        "unit" -> BsonString("week")))
    window

    A Bson representing the required window.

    returns

    The constructed window.
