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.
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 (durations.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;
}

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.

GeneratedMessageLiteGeneratedMessageLite.MethodToInvoke.
Theses 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.
MERGE_FROM_STREAM is parameterized with an CodedInputStream and
ExtensionRegistryLite. It consumes the input stream, parsing the contents into the
returned protocol buffer. If parsing throws an InvalidProtocolBufferException, the
implementation wraps it in a RuntimeException.
NEW_INSTANCE returns a new instance of the protocol buffer that has not yet been
made immutable. See MAKE_IMMUTABLE.
IS_INITIALIZED is parameterized with a Boolean detailing whether to
memoize. It returns null for false and the default instance for true. We optionally
memoize to support the Builder case, where memoization is not desired.
NEW_BUILDER returns a BuilderType instance.
VISIT is parameterized with a Visitor and a MessageType and
recursively iterates through the fields side by side between this and the instance.
MAKE_IMMUTABLE sets all internal fields to an immutable state.
For use by generated code only.
