#observe(timeout: nil, attributes: {}) ⇒ Object

Observe the ObservableCounter with fixed timeout duration.

Parameters:

  • timeout (int) (defaults to: nil) —

    The timeout duration for callback to run, which MUST be a non-negative numeric value.

  • attributes (Hash{String => String, Numeric, Boolean, Array<String, Numeric, Boolean>}) (defaults to: {}) —
