x == 0
when this == that
x > 0

This method returns whether this duration is finite, which is not the same as
!isInfinite
for Double because this method also returns false
for Duration.Undefined.

Utility for working with java.util.concurrent.TimeUnit durations.
This class is not meant as a general purpose representation of time, it is optimized for the needs of
scala.concurrent
.Basic Usage
Examples:
Invoking inexpressible conversions (like calling
toSeconds
on an infinite duration) will throw an IllegalArgumentException.Implicits are also provided for Int, Long and Double. Example usage:
The DSL provided by the implicit conversions always allows construction of finite durations, even for infinite Double inputs; use Duration.Inf instead.
Extractors, parsing and arithmetic are also included:
Handling of Time Units
Calculations performed on finite durations always retain the more precise unit of either operand, no matter whether a coarser unit would be able to exactly express the same duration. This means that Duration can be used as a lossless container for a (length, unit) pair if it is constructed using the corresponding methods and no arithmetic is performed on it; adding/subtracting durations should in that case be done with care.
Correspondence to Double Semantics
The semantics of arithmetic operations on Duration are two-fold:
java.lang.Double
when it comes to infinite or undefined valuesThe conversion between Duration and Double is done using Duration.toUnit (with unit NANOSECONDS) and Duration.fromNanos(Double)
Ordering
The default ordering is consistent with the ordering of Double numbers, which means that Undefined is considered greater than all other durations, including Duration.Inf.
