Detailed Description
Abstract interface implemented by Protocol Message objects.
This interface is implemented by all protocol message objects. Non-lite messages additionally implement the Message interface, which is a subclass of MessageLite. Use MessageLite instead when you only need the subset of features which it supports – namely, nothing that uses descriptors or reflection. You can instruct the protocol compiler to generate classes which implement only MessageLite, not the full Message interface, by adding the follow line to the .proto file:
option optimize_for = LITE_RUNTIME;
This is particularly useful on resource-constrained systems where the full protocol buffers runtime library is too big.
Note that on non-constrained systems (e.g. servers) when you need to link in lots of protocol definitions, a better way to reduce total code footprint is to use
. This will make the generated code smaller while still supporting all the same features (at the expense of speed).
is best when you only have a small number of message types linked into your binary, in which case the size of the protocol buffers runtime itself is the biggest problem.

◆ writeDelimitedTo() [1/2]
| void com.google.protobuf.MessageLite.writeDelimitedTo | ( | OutputStream | output | ) | throws IOException |
Like writeTo(OutputStream), but writes the size of the message as a varint before writing the data.

◆ writeTo() [1/4]
| void com.google.protobuf.MessageLite.writeTo | ( | CodedOutputStream | output | ) | throws IOException |

◆ writeTo() [3/4]
| void com.google.protobuf.MessageLite.writeTo | ( | OutputStream | output | ) | throws IOException |
Serializes the message and writes it to
. This is just a trivial wrapper around writeTo(CodedOutputStream). This does not flush or close the stream.
NOTE: Protocol Buffers are not self-delimiting. Therefore, if you write any more data to the stream after the message, you must somehow ensure that the parser on the receiving end does not interpret this as being part of the protocol message. This can be done e.g. by writing the size of the message before the data, then making sure to limit the input to that size on the receiving end (e.g. by wrapping the InputStream in one which limits the input). Alternatively, just use writeDelimitedTo(OutputStream).
Implemented in com.google.protobuf.UnknownFieldSet, com.google.protobuf.UnknownFieldSet, com.google.protobuf.AbstractMessageLite< MessageType extends AbstractMessageLite< MessageType, BuilderType, BuilderType extends AbstractMessageLite.Builder< MessageType, BuilderType >, and com.google.protobuf.AbstractMessageLite< MessageType extends AbstractMessageLite< MessageType, BuilderType, BuilderType extends AbstractMessageLite.Builder< MessageType, BuilderType >.
