public final class Duration
extends GeneratedMessageLite<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".

dynamicMethod
protected final Object dynamicMethod(GeneratedMessageLite.MethodToInvoke method, Object arg0, Object arg1) Description copied from class:GeneratedMessageLiteA method that implements different types of operations described inGeneratedMessageLite.MethodToInvoke. These different kinds of operations are required to implement message-level operations for builders in the runtime. This method bundles those operations to reduce the generated methods count.NEW_INSTANCEreturns a new instance of the protocol buffer that has not yet been made immutable. SeeMAKE_IMMUTABLE.IS_INITIALIZEDreturnsnullfor false and the default instance for true. It doesn't use or modify any memoized value.GET_MEMOIZED_IS_INITIALIZEDreturns the memoizedisInitializedbyte value.SET_MEMOIZED_IS_INITIALIZEDsets the memoizedisInitializedbyte value to 1 if the first parameter is not null, or to 0 if the first parameter is null.NEW_BUILDERreturns aBuilderTypeinstance.
For use by generated code only.
