类 MapField<K,V>

java.lang.Object

com.baidu.bjf.remoting.protobuf.MapField<K,V>

类型参数:

K - the key type

V - the value type

public class MapField<K,V>
extends Object

Internal representation of map fields in generated messages. This class supports accessing the map field as a Map to be used in generated API and also supports accessing the field as a List to be used in reflection API. It keeps track of where the data is currently stored and do necessary conversions between map and list. This class is a protobuf implementation detail. Users shouldn't use this class directly. THREAD-SAFETY NOTE: Read-only access is thread-safe. Users can call getMap() and getList() concurrently in multiple threads. If write-access is needed, all access must be synchronized.
