See theFiniteDuration companion object
final class FiniteDuration(val length: Long, val unit: TimeUnit) extends Duration

This class represents a finite duration. Its addition and subtraction operators are overloaded to retain this guarantee statically. The range of this class is limited to +-(2^63-1)ns, which is roughly 292 years.

override def equals(other: Any): Boolean

Compares the receiver object (this) with the argument object (that) for equivalence.

Compares the receiver object (this) with the argument object (that) for equivalence.

Any implementation of this method should be an equivalence relation:

- It is reflexive: for any instance x of type Any, x.equals(x) should return true. - It is symmetric: for any instances x and y of type Any, x.equals(y) should return true if and only if y.equals(x) returns true. - It is transitive: for any instances x, y, and z of type Any if x.equals(y) returns true and y.equals(z) returns true, then x.equals(z) should return true.

If you override this method, you should verify that your implementation remains an equivalence relation. Additionally, when overriding this method it is usually necessary to override hashCode to ensure that objects which are "equal" (o1.equals(o2) returns true) hash to the same scala.Int. (o1.hashCode.equals(o2.hashCode)).

## Value parameters

that

the object to compare against this object for equality.

## Attributes

Returns

true if the receiver object is equivalent to the argument; false otherwise.

override def hashCode: Int

Calculate a hash code value for the object.

Calculate a hash code value for the object.

The default hashing algorithm is platform dependent.

Note that it is allowed for two objects to have identical hash codes (o1.hashCode.equals(o2.hashCode)) yet not be equal (o1.equals(o2) returns false). A degenerate implementation could always return 0. However, it is required that if two objects are equal (o1.equals(o2) returns true) that they have identical hash codes (o1.hashCode.equals(o2.hashCode)). Therefore, when overriding this method, be sure to verify that the behavior is consistent with the equals method.

## Attributes

Returns

the hash code value for this object.

Return the number of nanoseconds as floating point number, scaled down to the given unit. The result may not precisely represent this duration due to the Double datatype's inherent limitations (mantissa size effectively 53 bits). Non-finite durations are represented as - Duration.Undefined is mapped to Double.NaN - Duration.Inf is mapped to Double.PositiveInfinity - Duration.MinusInf is mapped to Double.NegativeInfinity
