- com.google.protobuf.AbstractMessageLite
- - com.google.protobuf.AbstractMessage

    - - com.google.protobuf.Empty

All Implemented Interfaces:: EmptyOrBuilder , Message , MessageLite , MessageLiteOrBuilder , MessageOrBuilder , java.io.Serializable

public final class Empty 
extends com.google.protobuf.GeneratedMessageV3
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

    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:

```
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 com.google.protobuf.GeneratedMessageV3

    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:

  - 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:

    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

  - 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.
