类 MapEntryLite<K,V>

java.lang.Object

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

类型参数:

K - the key type

V - the value type

public class MapEntryLite<K,V>
extends Object

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. Protobuf internal. Users shouldn't use.

方法概要

限定符和类型	方法和说明
int	computeMessageSize(int fieldNumber, K key, V value) Computes the message size for the provided key and value as though they were wrapped by a MapEntryLite.
K	getKey() Gets the key.
V	getValue() Gets the value.
static <K,V> MapEntryLite<K,V>	newDefaultInstance(com.google.protobuf.WireFormat.FieldType keyType, K defaultKey, com.google.protobuf.WireFormat.FieldType valueType, V defaultValue) Creates a default MapEntryLite message instance.
Map.Entry<K,V>	parseEntry(com.google.protobuf.ByteString bytes, com.google.protobuf.ExtensionRegistryLite extensionRegistry) Parses an entry off of the input as a Map.Entry.
void	parseInto(MapFieldLite<K,V> map, com.google.protobuf.CodedInputStream input, com.google.protobuf.ExtensionRegistryLite extensionRegistry) Parses an entry off of the input into the map.
void	serializeTo(com.google.protobuf.CodedOutputStream output, int fieldNumber, K key, V value) Serializes the provided key and value as though they were wrapped by a MapEntryLite to the output stream.

方法详细资料

getKey

public K getKey()

Gets the key.

返回:

the key

getValue

public V getValue()

Gets the value.

返回:

the value

newDefaultInstance

public static <K,V> MapEntryLite<K,V> newDefaultInstance(com.google.protobuf.WireFormat.FieldType keyType,
                                                         K defaultKey,
                                                         com.google.protobuf.WireFormat.FieldType valueType,
                                                         V defaultValue)

Creates a default MapEntryLite message instance. 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.

类型参数:

K - the key type

V - the value type

参数:

keyType - the key type

defaultKey - the default key

valueType - the value type

defaultValue - the default value

返回:

the map entry lite

serializeTo

public void serializeTo(com.google.protobuf.CodedOutputStream output,
                        int fieldNumber,
                        K key,
                        V value)
                 throws IOException

Serializes the provided key and value as though they were wrapped by a MapEntryLite to the output stream. This helper method avoids allocation of a MapEntryLite built with a key and value and is called from generated code directly.

参数:

output - the output

fieldNumber - the field number

key - the key

value - the value

抛出:

IOException - Signals that an I/O exception has occurred.

computeMessageSize

public int computeMessageSize(int fieldNumber,
                              K key,
                              V value)

Computes the message size for the provided key and value as though they were wrapped by a MapEntryLite. This helper method avoids allocation of a MapEntryLite built with a key and value and is called from generated code directly.

参数:

fieldNumber - the field number

key - the key

value - the value

返回:

the int

parseEntry

public Map.Entry<K,V> parseEntry(com.google.protobuf.ByteString bytes,
                                 com.google.protobuf.ExtensionRegistryLite extensionRegistry)
                          throws IOException

Parses an entry off of the input as a Map.Entry. This helper requires an allocation so using parseInto(com.baidu.bjf.remoting.protobuf.MapFieldLite<K, V>, com.google.protobuf.CodedInputStream, com.google.protobuf.ExtensionRegistryLite) is preferred if possible.

参数:

bytes - the bytes

extensionRegistry - the extension registry

返回:

the map. entry

抛出:

IOException - Signals that an I/O exception has occurred.

parseInto

public void parseInto(MapFieldLite<K,V> map,
                      com.google.protobuf.CodedInputStream input,
                      com.google.protobuf.ExtensionRegistryLite extensionRegistry)
               throws IOException

Parses an entry off of the input into the map. This helper avoids allocaton of a MapEntryLite by parsing directly into the provided MapFieldLite.

参数:

map - the map

input - the input

extensionRegistry - the extension registry

抛出:

IOException - Signals that an I/O exception has occurred.
