    Modifier and Type
    Method
    Description
    Chronology
    getChronology()
    Gets the chronology of the instant.
    boolean
    intersects(Time time)
    Does this time intersects with the time passed.
    boolean
    isAbsolute()
    Checks if the time is an absolute temporal type, that is an object that doesn't has a time zone.
    boolean
    isInstant()
    Checks if the time is an instant, that is an object that represents a position in a time scale.
    boolean
    isInterval()
    Checks if the time is an interval, that is an object that represents a period of time between two instants.
    boolean
    isRelative()
    Checks if the time is a relative temporal type, that is an object that has a Chronology that establish how a time object can be converted into other object with date time fields.

  • Method Details

    • intersects

      boolean intersects(Time time)
      Does this time intersects with the time passed.
      Parameters:
      time - an instant to check against, null means now
      Returns:
      true if the time intersects with the time passed in

    • isRelative

      boolean isRelative()
      Checks if the time is a relative temporal type, that is an object that has a Chronology that establish how a time object can be converted into other object with date time fields.
      Returns:
      trueinvalid input: '<'/code) if the time object is relative

    • isAbsolute

      boolean isAbsolute()
      Checks if the time is an absolute temporal type, that is an object that doesn't has a time zone.
      Returns:
      true if the time object is absolute

    • isInterval

      boolean isInterval()
      Checks if the time is an interval, that is an object that represents a period of time between two instants.
      Returns:
      true if the time object is an interval

    • isInstant

      boolean isInstant()
      Checks if the time is an instant, that is an object that represents a position in a time scale. In practice, an instant is an interval whose duration is less than the resolution of the time scale.
      Returns:
      true if the time object is an instant.

    • getChronology

      Chronology getChronology()
      Gets the chronology of the instant. The Chronology provides conversion from the millisecond value to meaningful fields in a particular calendar system.
      Returns:
      the Chronology, never null
