    • setWindowFields

      public static <TExpression> Bson setWindowFields(@Nullable TExpression partitionBy, @Nullable Bson sortBy, WindowOutputField output, WindowOutputField... moreOutput)
      Creates a $setWindowFields pipeline stage, which allows using window operators. This stage partitions the input documents similarly to the $group pipeline stage, optionally sorts them, computes fields in the documents by computing window functions over windows specified per function, and outputs the documents. The important difference from the $group pipeline stage is that documents belonging to the same partition or window are not folded into a single document.
      Type Parameters:
      TExpression - The partitionBy expression type.
      Parameters:
      partitionBy - Optional partitioning of data specified like id in group(Object, List). If null, then all documents belong to the same partition.
      sortBy - Fields to sort by. The syntax is identical to sort in sort(Bson) (see Sorts). Sorting is required by certain functions and may be required by some windows (see Windows for more details). Sorting is used only for the purpose of computing window functions and does not guarantee ordering of the output documents.
      output - A windowed computation.
      moreOutput - More windowed computations.
      Returns:
      The $setWindowFields pipeline stage.
      Since:
      4.3

    • setWindowFields

      public static <TExpression> Bson setWindowFields(@Nullable TExpression partitionBy, @Nullable Bson sortBy, Iterable<? extends WindowOutputField> output)
      Creates a $setWindowFields pipeline stage, which allows using window operators. This stage partitions the input documents similarly to the $group pipeline stage, optionally sorts them, computes fields in the documents by computing window functions over windows specified per function, and outputs the documents. The important difference from the $group pipeline stage is that documents belonging to the same partition or window are not folded into a single document.
      Type Parameters:
      TExpression - The partitionBy expression type.
      Parameters:
      partitionBy - Optional partitioning of data specified like id in group(Object, List). If null, then all documents belong to the same partition.
      sortBy - Fields to sort by. The syntax is identical to sort in sort(Bson) (see Sorts). Sorting is required by certain functions and may be required by some windows (see Windows for more details). Sorting is used only for the purpose of computing window functions and does not guarantee ordering of the output documents.
      output - A list of windowed computations. Specifying an empty list is not an error, but the resulting stage does not do anything useful.
      Returns:
      The $setWindowFields pipeline stage.

      range - The range.
      Returns:
      The requested pipeline stage.

      public static Bson densify(String field, DensifyRange range, DensifyOptions options)

      Parameters:
      field - The field to densify.
