public static final class Duration.Builder
extends GeneratedMessageV3.Builder<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".Protobuf type

Get the FieldAccessorTable for this type. We can't have the message class pass this in to the constructor because of bootstrapping trouble with DescriptorProtos.- Specified by:

- Overrides:

-
getDefaultInstanceForType
Description copied from interface:MessageLiteOrBuilder
Get an instance of the type with no fields set. Because no fields are set, all getters for singular fields will return default values and repeated fields will appear empty. This may or may not be a singleton. This differs from thegetDefaultInstance()
method of generated message classes in that this method is an abstract method of theMessageLite
interface whereasgetDefaultInstance()
is a static method of a specific class. They return the same thing.- Specified by:

mergeFrom
Description copied from interface:Message.Builder
Mergeother
into the message being built.other
must have the exact same type asthis
(i.e.getDescriptorForType() == other.getDescriptorForType()
).Merging occurs as follows. For each field:
* For singular primitive fields, if the field is set inother
, thenother
's value overwrites the value in this message.
* For singular message fields, if the field is set inother
, it is merged into the corresponding sub-message of this message using the same merging rules.
* For repeated fields, the elements inother
are concatenated with the elements in this message.
* For oneof groups, if the other message has one of the fields set, the group of this message is cleared and replaced by the field of the other message, so that the oneof constraint is preserved.This is equivalent to the
Message::MergeFrom
method in C++.- Specified by:
