- - ### Field Detail

    - #### SAMPLING_RATE_NEVER

          public static final double SAMPLING_RATE_NEVER

      Min valid sampling rate with special meaning that span won't be created.
      See Also:
        Constant Field Values

    - #### SAMPLING_RATE_ALWAYS

          public static final double SAMPLING_RATE_ALWAYS

      Max valid sampling rate with special meaning that span will be always created.
      See Also:
        Constant Field Values

  - ### Method Detail

    - #### samplingRate

          public double samplingRate()

      Returns:
        Number between 0 and 1 that more or less reflects the probability of sampling specific trace. 0 and 1 have special meaning here, 0 means never 1 means always. Default value is 0 (never).

    - #### includedScopes

          @NotNull
          public @NotNull Set<Scope> includedScopes()

      Returns:
        Set of `Scope` that defines which sub-traces will be included in given trace. In other words, if child's span scope is equals to parent's scope or it belongs to the parent's span included scopes, then given child span will be attached to the current trace, otherwise it'll be skipped. See `Span.isChainable(Scope)` for more details. If no scopes are specified, empty set will be returned.

    - #### equals

          public boolean equals​(Object o)

      Overrides:
        `equals` in class `Object`
