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

类型参数:

K - the key type

V - the value type

所有已实现的接口:

Serializable, Cloneable, Map<K,V>

public final class MapFieldLite<K,V>
extends LinkedHashMap<K,V>

Internal representation of map fields in generated lite-runtime messages. This class is a protobuf implementation detail. Users shouldn't use this class directly.

mergeFrom

public void mergeFrom(MapFieldLite<K,V> other)

Merge from.

参数:

other - the other

entrySet

public Set<Map.Entry<K,V>> entrySet()

指定者:

entrySet 在接口中 Map<K,V>

覆盖:

entrySet 在类中 LinkedHashMap<K,V>

clear

public void clear()

指定者:

clear 在接口中 Map<K,V>

覆盖:

clear 在类中 LinkedHashMap<K,V>

put

public V put(K key,
 V value)

指定者:

put 在接口中 Map<K,V>

覆盖:

put 在类中 HashMap<K,V>

put

public V put(Map.Entry<K,V> entry)

Put.

参数:

entry - the entry

返回:

the v

putAll

public void putAll(Map<? extends K,? extends V> m)

指定者:

putAll 在接口中 Map<K,V>

覆盖:

putAll 在类中 HashMap<K,V>

remove

public V remove(Object key)

指定者:

remove 在接口中 Map<K,V>

覆盖:

remove 在类中 HashMap<K,V>

equals

public boolean equals(Object object)

Checks whether two map fields are equal.

指定者:

equals 在接口中 Map<K,V>

覆盖:

equals 在类中 AbstractMap<K,V>

返回:

the map field lite

makeImmutable

public void makeImmutable()

Makes this field immutable. All subsequent modifications will throw an UnsupportedOperationException.

isMutable

public boolean isMutable()

Checks if is mutable.

返回:

true, if is mutable
