Class Clock.FixedClock

  • All Implemented Interfaces:
    java.io.Serializable
    Enclosing class:
    Clock
    static final class Clock.FixedClock
extends Clock
implements java.io.Serializable
    Implementation of a clock that always returns the same instant. This is typically used for testing.

      • getZone

        public ZoneId getZone()
        Description copied from class: Clock
        Gets the time-zone being used to create dates and times.

        A clock will typically obtain the current instant and then convert that to a date or time using a time-zone. This method returns the time-zone used.

        Specified by:
        getZone in class Clock
        Returns:
        the time-zone being used to interpret instants, not null

      • withZone

        public Clock withZone​(ZoneId zone)
        Description copied from class: Clock
        Returns a copy of this clock with a different time-zone.

        A clock will typically obtain the current instant and then convert that to a date or time using a time-zone. This method returns a clock with similar properties but using a different time-zone.

        Specified by:
        withZone in class Clock
        Parameters:
        zone - the time-zone to change to, not null
        Returns:
        a clock based on this clock with the specified time-zone, not null

      • millis

        public long millis()
        Description copied from class: Clock
        Gets the current millisecond instant of the clock.

        This returns the millisecond-based instant, measured from 1970-01-01T00:00 UTC. This is equivalent to the definition of System.currentTimeMillis().

        Most applications should avoid this method and use Instant to represent an instant on the time-line rather than a raw millisecond value. This method is provided to allow the use of the clock in high performance use cases where the creation of an object would be unacceptable. The default implementation currently calls Clock.instant().

        Overrides:
        millis in class Clock
        Returns:
        the current millisecond instant from this clock, measured from the Java epoch of 1970-01-01T00:00 UTC, not null

      • instant

        public Instant instant()
        Description copied from class: Clock
        Gets the current instant of the clock.

        This returns an instant representing the current instant as defined by the clock.

        Specified by:
        instant in class Clock
        Returns:
        the current instant from this clock, not null

      • equals

        public boolean equals​(java.lang.Object obj)
        Description copied from class: Clock
        Checks if this clock is equal to another clock.

        Clocks must compare equal based on their state and behavior.

        Overrides:
        equals in class Clock
        Parameters:
        obj - the object to check, null returns false
        Returns:
        true if this is equal to the other clock

      • hashCode

        public int hashCode()
        Description copied from class: Clock
        A hash code for this clock.
        Overrides:
        hashCode in class Clock
        Returns:
        a suitable hash code

      • toString

        public java.lang.String toString()
        Overrides:
        toString in class java.lang.Object
