publicclassMapEntryLite<K,V>
Implements the lite version of map entry messages.
This class serves as an utility class to help do serialization/parsing of map entries. It's
used in generated code and also in the full version MapEntry message.
This method is used by generated code to create the default instance for a map entry
message. The created default instance should be used to create new map entry messages of the
same type. For each map entry message, only one default instance should be created.
Computes the message size for the provided key and value as though they were wrapped by aMapEntryLite. This helper method avoids allocation of aMapEntryLitebuilt with
a key and value and is called from generated code directly.
Serializes the provided key and value as though they were wrapped by aMapEntryLiteto
the output stream. This helper method avoids allocation of aMapEntryLitebuilt with a
key and value and is called from generated code directly.
