Warning: This does not verify that all required fields are present in the input message.
If you call MessageLite.Builder.build()
without setting all required fields, it will throw an UninitializedMessageException
, which is a RuntimeException
and thus might not be
caught. There are a few good ways to deal with this:
MessageLiteOrBuilder.isInitialized()
to verify that all required fields are set before
building.
buildPartial()
to build, which ignores missing required fields.
Note: The caller should call CodedInputStream.checkLastTagWas(int)
after calling
this to verify that the last tag seen was the appropriate end-group tag, or zero for EOF.

input
and merge it with the message being built.
This is just a small wrapper around MessageLite.Builder.mergeFrom(CodedInputStream)
. Note that this
method always reads the entire input (unless it throws an exception). If you want it
to stop earlier, you will need to wrap your input in some wrapper stream that limits reading.
Or, use MessageLite.writeDelimitedTo(OutputStream)
to write your message and MessageLite.Builder.mergeDelimitedFrom(InputStream)
to read it.
Despite usually reading the entire input, this does not close the stream.

other
into the message being built. other
must have the exact same type
as this
(i.e. getClass().equals(getDefaultInstanceForType().getClass())
).
Merging occurs as follows. For each field:
* For singular primitive fields, if the field is set in other
, then other
's
value overwrites the value in this message.
* For singular message fields, if the field is set in other
, it is merged into the
corresponding sub-message of this message using the same merging rules.
* For repeated fields, the elements in other
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++.
