Package com.google.protobuf

Class MapEntryLite<K,V>

java.lang.Object

com.google.protobuf.MapEntryLite<K,V>

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.

Method Summary

Modifier and Type	Method	Description
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()
V	getValue()
static <K, V> MapEntryLite<K,V>	newDefaultInstance(WireFormat.FieldType keyType, K defaultKey, WireFormat.FieldType valueType, V defaultValue)	Creates a default MapEntryLite message instance.
Map.Entry<K,V>	parseEntry(ByteString bytes, ExtensionRegistryLite extensionRegistry)	Parses an entry off of the input as a Map.Entry.
void	parseInto(MapFieldLite<K,V> map, CodedInputStream input, ExtensionRegistryLite extensionRegistry)	Parses an entry off of the input into the map.
void	serializeTo(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.

Method Details

getKey

public K getKey()

getValue

public V getValue()

newDefaultInstance

public static <K,
V> MapEntryLite<K,V> newDefaultInstance(WireFormat.FieldType keyType,
 K defaultKey,
 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.

serializeTo

public void serializeTo(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.

Throws:

IOException

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.

parseEntry

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

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

Throws:

IOException

parseInto

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

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

Throws:

IOException
