class DocumentTransform
  # A transformation of a field of the document.
  # @!attribute [rw] field_path
  #   @return [String]
  #     The path of the field. See {Google::Firestore::V1::Document#fields Document#fields} for the field path syntax
  #     reference.
  # @!attribute [rw] set_to_server_value
  #   @return [Google::Firestore::V1::DocumentTransform::FieldTransform::ServerValue]
  #     Sets the field to the given server value.
  # @!attribute [rw] increment
  #   @return [Google::Firestore::V1::Value]
  #     Adds the given value to the field's current value.
  #
  #     This must be an integer or a double value.
  #     If the field is not an integer or double, or if the field does not yet
  #     exist, the transformation will set the field to the given value.
  #     If either of the given value or the current field value are doubles,
  #     both values will be interpreted as doubles. Double arithmetic and
  #     representation of double values follow IEEE 754 semantics.
  #     If there is positive/negative integer overflow, the field is resolved
  #     to the largest magnitude positive/negative integer.
  # @!attribute [rw] maximum
  #   @return [Google::Firestore::V1::Value]
  #     Sets the field to the maximum of its current value and the given value.
  #
  #     This must be an integer or a double value.
  #     If the field is not an integer or double, or if the field does not yet
  #     exist, the transformation will set the field to the given value.
  #     If a maximum operation is applied where the field and the input value
  #     are of mixed types (that is - one is an integer and one is a double)
  #     the field takes on the type of the larger operand. If the operands are
  #     equivalent (e.g. 3 and 3.0), the field does not change.
  #     0, 0.0, and -0.0 are all zero. The maximum of a zero stored value and
  #     zero input value is always the stored value.
  #     The maximum of any numeric value x and NaN is NaN.
  # @!attribute [rw] minimum
  #   @return [Google::Firestore::V1::Value]
  #     Sets the field to the minimum of its current value and the given value.
  #
  #     This must be an integer or a double value.
  #     If the field is not an integer or double, or if the field does not yet
  #     exist, the transformation will set the field to the input value.
  #     If a minimum operation is applied where the field and the input value
  #     are of mixed types (that is - one is an integer and one is a double)
  #     the field takes on the type of the smaller operand. If the operands are
  #     equivalent (e.g. 3 and 3.0), the field does not change.
  #     0, 0.0, and -0.0 are all zero. The minimum of a zero stored value and
  #     zero input value is always the stored value.
  #     The minimum of any numeric value x and NaN is NaN.
  # @!attribute [rw] append_missing_elements
  #   @return [Google::Firestore::V1::ArrayValue]
  #     Append the given elements in order if they are not already present in
  #     the current field value.
  #     If the field is not an array, or if the field does not yet exist, it is
  #     first set to the empty array.
  #
  #     Equivalent numbers of different types (e.g. 3L and 3.0) are
  #     considered equal when checking if a value is missing.
  #     NaN is equal to NaN, and Null is equal to Null.
  #     If the input contains multiple equivalent values, only the first will
  #     be considered.
  #
  #     The corresponding transform_result will be the null value.
  # @!attribute [rw] remove_all_from_array
  #   @return [Google::Firestore::V1::ArrayValue]
  #     Remove all of the given elements from the array in the field.
  #     If the field is not an array, or if the field does not yet exist, it is
  #     set to the empty array.
  #
  #     Equivalent numbers of the different types (e.g. 3L and 3.0) are
  #     considered equal when deciding whether an element should be removed.
  #     NaN is equal to NaN, and Null is equal to Null.
  #     This will remove all equivalent values if there are duplicates.
  #
  #     The corresponding transform_result will be the null value.
  class FieldTransform
    # A value that is calculated by the server.
    module ServerValue
      # Unspecified. This value must not be used.
      SERVER_VALUE_UNSPECIFIED = 0

      # The time at which the server processed the request, with millisecond
