MessageLite.Builder
Message.Builder mergeFrom(Message other)
other into the message being built.
other must have the exact same type as
this (i.e.
getDescriptorForType() == other.getDescriptorForType()). Merging occurs as follows. For each field:
other, then
other's value overwrites the value in this message.
other, it is merged into the corresponding sub-message of this message using the same merging rules.
other are concatenated with the elements in this message. This is equivalent to the
Message::MergeFrom method in C++.
Messagebuild()
MessageLite.Builder
MessagebuildPartial()
MessageLite.Builder
MessageLite.Builder.build() , but does not throw an exception if the message is missing required fields. Instead, a partial message is returned. Subsequent changes to the Builder will not affect the returned message.
Message.Builder clone()
MessageLite.Builder
clone in interface
MessageLite.Builder
Object.clone()
Message.Builder mergeFrom(CodedInputStream input) throws IOException
MessageLite.Builder
Warning: This does not verify that all required fields are present in the input message. If you call MessageLite 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 after calling this to verify that the last tag seen was the appropriate end-group tag, or zero for EOF.

Message.Builder mergeFrom(CodedInputStream input, ExtensionRegistryLite extensionRegistry) throws IOException
MessageLite.Builder
MessageLite.Builder.mergeFrom(CodedInputStream) , but also parses extensions. The extensions that you want to be able to parse must be registered in
extensionRegistry. Extensions not in the registry will be treated as unknown fields.

IOException
Descriptors.Descriptor getDescriptorForType()
MessageOrBuilder.getDescriptorForType() .
Message.Builder newBuilderForField(Descriptors .FieldDescriptor field)
Message.Builder getFieldBuilder(Descriptors .FieldDescriptor field)
Normally, we hold a reference to the immutable message object for the message type field. Some implementations(the generated message builders), however, can also hold a reference to the builder object (a nested builder) for the field.
If the field is already backed up by a nested builder, the nested builder will be returned. Otherwise, a new field builder will be created and returned. The original message field (if exist) will be merged into the field builder, which will then be nested into its parent builder.
NOTE: implementations that do not support nested builders will throw UnsupportedException.
Message.Builder setField(Descriptors .FieldDescriptor field, Object value)
MessageOrBuilder.getField(Descriptors.FieldDescriptor) would return.
Message.Builder clearField(Descriptors .FieldDescriptor field)
Message.Builder clearOneof(Descriptors .OneofDescriptor oneof)
Message.Builder setRepeatedField(Descriptors .FieldDescriptor field, int index, Object value)
MessageOrBuilder.getRepeatedField(Descriptors.FieldDescriptor,int) would return.
IllegalArgumentException - The field is not a repeated field, or
field.getContainingType() != getDescriptorForType().
Message.Builder addRepeatedField(Descriptors .FieldDescriptor field, Object value)
setRepeatedField, but appends the value as a new element.
IllegalArgumentException - The field is not a repeated field, or
field.getContainingType() != getDescriptorForType().
Message.Builder setUnknownFields(UnknownFieldSet unknownFields)
UnknownFieldSet for this message.
Message.Builder mergeUnknownFields(UnknownFieldSet unknownFields)
UnknownFieldSet for this message.

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.
