All Implemented Interfaces:

public final class Empty
extends GeneratedMessage
implements EmptyOrBuilder

Protobuf type google.protobuf.Empty

 A generic empty message that you can re-use to avoid defining duplicated
 empty messages in your APIs. A typical example is to use it as the request
 or the response type of an API method. For instance:
     service Foo {
       rpc Bar(google.protobuf.Empty) returns (google.protobuf.Empty);
     }
 The JSON representation for `Empty` is empty JSON object `{}`.

Method Detail

getUnknownFields

public final UnknownFieldSet getUnknownFields()

Description copied from interface: MessageOrBuilder

Get the UnknownFieldSet for this message.

Specified by:

getUnknownFields in interface MessageOrBuilder

Overrides:

getUnknownFields in class GeneratedMessage

getDescriptor

public static final Descriptors.Descriptor getDescriptor()

isInitialized

public final boolean isInitialized()

Description copied from interface: MessageLiteOrBuilder

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

See also: MessageOrBuilder.getInitializationErrorString()

Specified by:

isInitialized in interface MessageLiteOrBuilder

Overrides:

isInitialized in class GeneratedMessage

writeTo

public void writeTo(CodedOutputStream output)
             throws java.io.IOException

Description copied from interface: MessageLite

Serializes the message and writes it to output. This does not flush or close the stream.

Specified by:

writeTo in interface MessageLite

Overrides:

writeTo in class GeneratedMessage

Throws:

java.io.IOException

getSerializedSize

public int getSerializedSize()

Description copied from interface: MessageLite

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

Specified by:

getSerializedSize in interface MessageLite

Overrides:

getSerializedSize in class GeneratedMessage

equals

public boolean equals(java.lang.Object obj)

Description copied from interface: Message

Compares the specified object with this message for equality. Returns true if the given object is a message of the same type (as defined by getDescriptorForType()) and has identical values for all of its fields. Subclasses must implement this; inheriting Object.equals() is incorrect.

Specified by:

equals in interface Message

Overrides:

equals in class AbstractMessage

Parameters:

obj - object to be compared for equality with this message

Returns:

true if the specified object is equal to this message

hashCode

public int hashCode()

Description copied from interface: Message

Returns the hash code value for this message. The hash code of a message should mix the message's type (object identity of the descriptor) with its contents (known and unknown field values). Subclasses must implement this; inheriting Object.hashCode() is incorrect.

Specified by:

hashCode in interface Message

Overrides:

hashCode in class AbstractMessage

Returns:

the hash code value for this message

Specified by:

newBuilderForType in interface Message

Specified by:

newBuilderForType in interface MessageLite

newBuilder

public static Empty.Builder newBuilder()

newBuilder

public static Empty.Builder newBuilder(Empty prototype)

toBuilder

public Empty.Builder toBuilder()

Description copied from interface: MessageLite

Constructs a builder initialized with the current message. Use this to derive a new message from the current one.

getDefaultInstance

public static Empty getDefaultInstance()

parser

public static Parser<Empty> parser()

getParserForType

public Parser<Empty> getParserForType()

Description copied from interface: MessageLite

Gets the parser for a message of the same type as this message.

Specified by:

getParserForType in interface Message

Specified by:

getParserForType in interface MessageLite

Overrides:

getParserForType in class GeneratedMessage

getDefaultInstanceForType

public Empty getDefaultInstanceForType()

Description copied from interface: MessageLiteOrBuilder

Get an instance of the type with no fields set. Because no fields are set, all getters for singular fields will return default values and repeated fields will appear empty. This may or may not be a singleton. This differs from the getDefaultInstance() method of generated message classes in that this method is an abstract method of the MessageLite interface whereas getDefaultInstance() is a static method of a specific class. They return the same thing.

getDefaultInstanceForType in interface MessageLiteOrBuilder
