  This is the documentation for the MongoDB Scala driver.

  Driver structure

  The mongodb scala driver.

  To get started you need a MongoClient instance, either from a connection string or via a org.mongodb.scala.MongoClientSettings.

  Notable packages include:

  • MongoClient The MongoClient used to connect and access MongoDB
  • MongoDatabase Providing access to a specific database
  • MongoCollection Providing access to a specific collection in a database.

•  object Windows

  Builders for windows used when expressing windowed computations.

  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.
