Class Duration.Builder

  • All Implemented Interfaces:
    DurationOrBuilder, MessageLite.Builder, MessageLiteOrBuilder, java.lang.Cloneable
    Enclosing class:
    Duration

    public static final class Duration.Builder
    extends GeneratedMessageLite.Builder<Duration,​Duration.Builder>
    implements DurationOrBuilder
     A Duration represents a signed, fixed-length span of time represented
     as a count of seconds and fractions of seconds at nanosecond
     resolution. It is independent of any calendar and concepts like "day"
     or "month". It is related to Timestamp in that the difference between
     two Timestamp values is a Duration and it can be added or subtracted
     from a Timestamp. Range is approximately +-10,000 years.
     # Examples
     Example 1: Compute Duration from two Timestamps in pseudo code.
         Timestamp start = ...;
         Timestamp end = ...;
         Duration duration = ...;
         duration.seconds = end.seconds - start.seconds;
         duration.nanos = end.nanos - start.nanos;
         if (duration.seconds < 0 && duration.nanos > 0) {
           duration.seconds += 1;
           duration.nanos -= 1000000000;
         } else if (duration.seconds > 0 && duration.nanos < 0) {
           duration.seconds -= 1;
           duration.nanos += 1000000000;
         }
     Example 2: Compute Timestamp from Timestamp + Duration in pseudo code.
         Timestamp start = ...;
         Duration duration = ...;
         Timestamp end = ...;
         end.seconds = start.seconds + duration.seconds;
         end.nanos = start.nanos + duration.nanos;
         if (end.nanos < 0) {
           end.seconds -= 1;
           end.nanos += 1000000000;
         } else if (end.nanos >= 1000000000) {
           end.seconds += 1;
           end.nanos -= 1000000000;
         }
     Example 3: Compute Duration from datetime.timedelta in Python.
         td = datetime.timedelta(days=3, minutes=10)
         duration = Duration()
         duration.FromTimedelta(td)
     # JSON Mapping
     In JSON format, the Duration type is encoded as a string rather than an
     object, where the string ends in the suffix "s" (indicating seconds) and
     is preceded by the number of seconds, with nanoseconds expressed as
     fractional seconds. For example, 3 seconds with 0 nanoseconds should be
     encoded in JSON format as "3s", while 3 seconds and 1 nanosecond should
     be expressed in JSON format as "3.000000001s", and 3 seconds and 1
     microsecond should be expressed in JSON format as "3.000001s".

      • getSeconds

        public long getSeconds()
         Signed seconds of the span of time. Must be from -315,576,000,000
         to +315,576,000,000 inclusive. Note: these bounds are computed from:
         60 sec/min * 60 min/hr * 24 hr/day * 365.25 days/year * 10000 years
         
        int64 seconds = 1;
        Specified by:
        getSeconds in interface DurationOrBuilder
        Returns:
        The seconds.
      • setSeconds

        public Duration.Builder setSeconds​(long value)
         Signed seconds of the span of time. Must be from -315,576,000,000
         to +315,576,000,000 inclusive. Note: these bounds are computed from:
         60 sec/min * 60 min/hr * 24 hr/day * 365.25 days/year * 10000 years
         
        int64 seconds = 1;
        Parameters:
        value - The seconds to set.
        Returns:
        This builder for chaining.
      • clearSeconds

        public Duration.Builder clearSeconds()
         Signed seconds of the span of time. Must be from -315,576,000,000
         to +315,576,000,000 inclusive. Note: these bounds are computed from:
         60 sec/min * 60 min/hr * 24 hr/day * 365.25 days/year * 10000 years

      • getNanos

        public int getNanos()
         Signed fractions of a second at nanosecond resolution of the span
         of time. Durations less than one second are represented with a 0
         `seconds` field and a positive or negative `nanos` field. For durations
         of one second or more, a non-zero value for the `nanos` field must be
         of the same sign as the `seconds` field. Must be from -999,999,999
         to +999,999,999 inclusive.
         
        int32 nanos = 2;

      • setNanos

        public Duration.Builder setNanos​(int value)
         Signed fractions of a second at nanosecond resolution of the span
         of time. Durations less than one second are represented with a 0
         `seconds` field and a positive or negative `nanos` field. For durations
         of one second or more, a non-zero value for the `nanos` field must be
