示例1: mergeMapEntry
import com.google.protobuf.nano.MapFactories.MapFactory; //導入依賴的package包/類
/**
* Merges the map entry into the map field. Note this is only supposed to
* be called by generated messages.
*
* @param map the map field; may be null, in which case a map will be
* instantiated using the {@link MapFactories.MapFactory}
* @param input the input byte buffer
* @param keyType key type, as defined in InternalNano.TYPE_*
* @param valueType value type, as defined in InternalNano.TYPE_*
* @param value an new instance of the value, if the value is a TYPE_MESSAGE;
* otherwise this parameter can be null and will be ignored.
* @param keyTag wire tag for the key
* @param valueTag wire tag for the value
* @return the map field
* @throws IOException
