Class Duration.Builder

All Implemented Interfaces:
DurationOrBuilder, MessageLite.Builder, MessageLiteOrBuilder, 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
       
      int64 seconds = 1;
      Returns:
      This builder for chaining.
    • 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;
      Specified by:
      getNanos in interface DurationOrBuilder
      Returns:
      The nanos.
    • 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
       of the same sign as the `seconds` field. Must be from -999,999,999
       to +999,999,999 inclusive.
       
      int32 nanos = 2;
      Parameters:
      value - The nanos to set.
      Returns:
      This builder for chaining.
    • clearNanos

      public Duration.Builder clearNanos()
       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
