Enclosing class:

Empty

public static final class Empty.Builder
extends GeneratedMessageV3.Builder<Empty.Builder>
implements EmptyOrBuilder

 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 `{}`.
 

Protobuf type google.protobuf.Empty

Method Detail

getDescriptor

public static final Descriptors.Descriptor getDescriptor()

internalGetFieldAccessorTable

protected GeneratedMessageV3.FieldAccessorTable internalGetFieldAccessorTable()

Description copied from class: GeneratedMessageV3.Builder

Get the FieldAccessorTable for this type. We can't have the message class pass this in to the constructor because of bootstrapping trouble with DescriptorProtos.

Specified by:

internalGetFieldAccessorTable in class GeneratedMessageV3.Builder<Empty.Builder>

clear

public Empty.Builder clear()

Description copied from class: GeneratedMessageV3.Builder

Called by the initialization and clear code paths to allow subclasses to reset any of their builtin fields back to the initial values.

Specified by:

clear in interface Message.Builder

Specified by:

clear in interface MessageLite.Builder

Overrides:

clear in class GeneratedMessageV3.Builder<Empty.Builder>

getDescriptorForType

public Descriptors.Descriptor getDescriptorForType()

Description copied from interface: Message.Builder

Get the message's type's descriptor. See MessageOrBuilder.getDescriptorForType().

Specified by:

getDescriptorForType in interface Message.Builder

Specified by:

getDescriptorForType in interface MessageOrBuilder

Overrides:

getDescriptorForType in class GeneratedMessageV3.Builder<Empty.Builder>

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.

Specified by:

getDefaultInstanceForType in interface MessageLiteOrBuilder

Specified by:

getDefaultInstanceForType in interface MessageOrBuilder

build

public Empty build()

Description copied from interface: MessageLite.Builder

Constructs the message based on the state of the Builder. Subsequent changes to the Builder will not affect the returned message.

Specified by:

build in interface Message.Builder

Specified by:

build in interface MessageLite.Builder

buildPartial

public Empty buildPartial()

Description copied from interface: MessageLite.Builder

Like MessageLite.Builder.build(), but does not throw an exception if the message is missing required fields. Instead, a partial message is returned. Subsequent changes to the Builder will not affect the returned message.

Specified by:

buildPartial in interface Message.Builder

Specified by:

buildPartial in interface MessageLite.Builder

clone

public Empty.Builder clone()

Description copied from interface: MessageLite.Builder

Clones the Builder.

Specified by:

clone in interface Message.Builder

Specified by:

clone in interface MessageLite.Builder

Overrides:

clone in class GeneratedMessageV3.Builder<Empty.Builder>

See Also:

Object.clone()

setField

public Empty.Builder setField(Descriptors.FieldDescriptor field,
                              Object value)

Description copied from interface: Message.Builder

Sets a field to the given value. The value must be of the correct type for this field, i.e. the same type that MessageOrBuilder.getField(Descriptors.FieldDescriptor) would return.

Specified by:

setField in interface Message.Builder

Overrides:

setField in class GeneratedMessageV3.Builder<Empty.Builder>

clearField

public Empty.Builder clearField(Descriptors.FieldDescriptor field)

Description copied from interface: Message.Builder

Clears the field. This is exactly equivalent to calling the generated "clear" accessor method corresponding to the field.

Specified by:

clearField in interface Message.Builder

Overrides:

clearField in class GeneratedMessageV3.Builder<Empty.Builder>

clearOneof

public Empty.Builder clearOneof(Descriptors.OneofDescriptor oneof)

Description copied from class: AbstractMessage.Builder

TODO(jieluo): Clear it when all subclasses have implemented this method.

Specified by:

clearOneof in interface Message.Builder

Overrides:

clearOneof in class GeneratedMessageV3.Builder<Empty.Builder>

setRepeatedField

public Empty.Builder setRepeatedField(Descriptors.FieldDescriptor field,
                                      int index,
                                      Object value)

Description copied from interface: Message.Builder

Sets an element of a repeated field to the given value. The value must be of the correct type for this field, i.e. the same type that MessageOrBuilder.getRepeatedField(Descriptors.FieldDescriptor,int) would return.

Specified by:

setRepeatedField in interface Message.Builder

Overrides:

setRepeatedField in class GeneratedMessageV3.Builder<Empty.Builder>

addRepeatedField

public Empty.Builder addRepeatedField(Descriptors.FieldDescriptor field,
                                      Object value)

Description copied from interface: Message.Builder

Like setRepeatedField, but appends the value as a new element.

Specified by:

addRepeatedField in interface Message.Builder

Overrides:

addRepeatedField in class GeneratedMessageV3.Builder<Empty.Builder>

mergeFrom

public Empty.Builder mergeFrom(Message other)

Description copied from interface: Message.Builder

Merge other into the message being built. other must have the exact same type as this (i.e. getDescriptorForType() == other.getDescriptorForType()).

Merging occurs as follows. For each field:
* For singular primitive fields, if the field is set in other, then other's value overwrites the value in this message.
* For singular message fields, if the field is set in other, it is merged into the corresponding sub-message of this message using the same merging rules.
* For repeated fields, the elements in other are concatenated with the elements in this message.
* For oneof groups, if the other message has one of the fields set, the group of this message is cleared and replaced by the field of the other message, so that the oneof constraint is preserved.

This is equivalent to the Message::MergeFrom method in C++.

Specified by:

mergeFrom in interface Message.Builder

Overrides:

mergeFrom in class AbstractMessage.Builder<Empty.Builder>

mergeFrom

public Empty.Builder mergeFrom(Empty other)

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 GeneratedMessageV3.Builder<Empty.Builder>

mergeFrom

public Empty.Builder mergeFrom(CodedInputStream input,
                               ExtensionRegistryLite extensionRegistry)
                        throws IOException

Description copied from interface: MessageLite.Builder

Like MessageLite.Builder.mergeFrom(CodedInputStream), but also parses extensions. The extensions that you want to be able to parse must be registered in extensionRegistry. Extensions not in the registry will be treated as unknown fields.

Specified by:

mergeFrom in interface Message.Builder

Specified by:

mergeFrom in interface MessageLite.Builder

Overrides:

mergeFrom in class AbstractMessage.Builder<Empty.Builder>

Throws:

IOException
