# Duration

#### sealed abstract class Duration extends Serializable with Ordered[Duration]

#### 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:

    import scala.concurrent.duration._

    val duration = Duration(100, MILLISECONDS)
    val duration = Duration(100, "millis")

    duration.toNanos
    duration < 1.second
    duration <= Duration.Inf

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:

    import scala.concurrent.duration._

    val duration = 100 millis

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:

    val d = Duration("1.2 ￂﾵs")
    val Duration(length, unit) = 5 millis
    val d2 = d * 2.5
    val d3 = d2 + 1.millisecond

#### 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:

- exact addition/subtraction with nanosecond resolution for finite durations, independent of the summands' magnitude
- isomorphic to `java.lang.Double` when it comes to infinite or undefined values

The 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.

    Cast the receiver object to be of type `T0`.

    Cast the receiver object to be of type `T0`.

    Note that the success of a cast at runtime is modulo Scala's erasure semantics. Therefore the expression `1.asInstanceOf[String]` will throw a `ClassCastException` at runtime, while the expression `List(1).asInstanceOf[List[String]]` will not. In the latter example, because the type argument is erased as part of compilation it is not possible to check whether the contents of the list are of the requested type.

20. #### final def eq(arg0: AnyRef): Boolean

    Tests whether the argument (`arg0`) is a reference to the receiver object (`this`).

    Tests whether the argument (`arg0`) is a reference to the receiver object (`this`).

    The `eq` method implements an equivalence relation on non-null instances of `AnyRef`, and has three additional properties:

    - It is consistent: for any non-null instances `x` and `y` of type `AnyRef`, multiple invocations of `x.eq(y)` consistently returns `true` or consistently returns `false`.
    - For any non-null instance `x` of type `AnyRef`, `x.eq(null)` and `null.eq(x)` returns `false`.
    - `null.eq(null)` returns `true`.

    When overriding the `equals` or `hashCode` methods, it is important to ensure that their behavior is consistent with reference equality. Therefore, if two objects are references to each other (`o1 eq o2`), they should be equal to each other (`o1 == o2`) and they should hash to the same value (`o1.hashCode == o2.hashCode`).

    returns

      `true` if the argument is a reference to the receiver object; `false` otherwise.

28. #### final def isInstanceOf[T0]: Boolean

    Test whether the dynamic type of the receiver object is `T0`.

    Test whether the dynamic type of the receiver object is `T0`.

    Note that the result of the test is modulo Scala's erasure semantics. Therefore the expression `1.isInstanceOf[String]` will return `false`, while the expression `List(1).isInstanceOf[List[String]]` will return `true`. In the latter example, because the type argument is erased as part of compilation it is not possible to check whether the contents of the list are of the specified type.

8. #### val self: Any

   Implicit information
     This member is added by an implicit conversion from Duration to StringAdd performed by method any2stringadd in scala.Predef.
   Shadowing
     This implicitly inherited member is ambiguous. One or more implicitly inherited members have similar signatures, so calling this member may produce an ambiguous implicit conversion compiler error.
     To access this member you can use a type ascription:

         (duration: StringAdd).self

   Definition Classes
     StringAdd

9. #### val self: Any

   Implicit information
     This member is added by an implicit conversion from Duration to StringFormat performed by method any2stringfmt in scala.Predef.
   Shadowing
     This implicitly inherited member is ambiguous. One or more implicitly inherited members have similar signatures, so calling this member may produce an ambiguous implicit conversion compiler error.
     To access this member you can use a type ascription:

     StringFormat

10. #### def toString(): String

    Creates a String representation of this object.

    Creates a String representation of this object. The default representation is platform dependent. On the java platform it is the concatenation of the class name, "@", and the object's hashcode in hexadecimal.

    returns

      a String representation of the object.

    Implicit information
      This member is added by an implicit conversion from Duration to (Long, TimeUnit) performed by method durationToPair in scala.concurrent.duration.
    Shadowing
      This implicitly inherited member is shadowed by one or more members in this class.
      To access this member you can use a type ascription:

          (duration: (Long, TimeUnit)).toString()
