Examples of com.google.protobuf.MessageLite

com.google.protobuf.MessageLite
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 {@code optimize_for = CODE_SIZE}. This will make the generated code smaller while still supporting all the same features (at the expense of speed). {@code optimize_for = LITE_RUNTIME} is best when you only have asmall number of message types linked into your binary, in which case the size of the protocol buffers runtime itself is the biggest problem. @author kenton@google.com Kenton Varda
