Class MapEntry<K,V> (3.19.4) 

public final class MapEntry<K,V> extends AbstractMessage

Implements MapEntry messages.

In reflection API, map fields will be treated as repeated message fields and each map entry is accessed as a message. This MapEntry class is used to represent these map entry messages in reflection API.

Protobuf internal. Users shouldn't use this class.

Static Methods

<K,V>newDefaultInstance(Descriptors.Descriptor descriptor, WireFormat.FieldType keyType, K defaultKey, WireFormat.FieldType valueType, V defaultValue)

public static MapEntry<K,V> <K,V>newDefaultInstance(Descriptors.Descriptor descriptor, WireFormat.FieldType keyType, K defaultKey, WireFormat.FieldType valueType, V defaultValue)

Create a default MapEntry instance. A default MapEntry instance should be created only once for each map entry message type. Generated code should store the created default instance and use it later to create new MapEntry messages of the same type.

Parameters
Name Description
descriptor Descriptors.Descriptor
keyType WireFormat.FieldType
defaultKey K
valueType WireFormat.FieldType
defaultValue V
Returns
Type Description
MapEntry<K,V>

getSerializedSize()

public int getSerializedSize()

Get the number of bytes required to encode this message. The result is only computed on the first call and memoized after that.

If this message requires more than Integer.MAX_VALUE bytes to encode, the return value will be smaller than the actual number of bytes required and might be negative.

Returns

Parameter
Name Description
field Descriptors.FieldDescriptor
Returns
Type Description
boolean

isInitialized()

public boolean isInitialized()

Returns true if all required fields in the message and all embedded messages are set, false otherwise.
