@CheckReturnValue public interface Message extends MessageLite, MessageOrBuilder
Abstract interface implemented by Protocol Message objects.See also
MessageLite
, which defines most of the methods that typical users care about.Message
adds methods that are not available in the "lite" runtime. The biggest added features are introspection and reflection; that is, getting descriptors for the message type and accessing the field values dynamically.

getParserForType
Parser<? extends Message> getParserForType()
Description copied from interface:MessageLite
Gets the parser for a message of the same type as this message.- Specified by:
getParserForType
in interfaceMessageLite
-
equals
boolean equals(java.lang.Object other)
Compares the specified object with this message for equality. Returnstrue
if the given object is a message of the same type (as defined bygetDescriptorForType()
) and has identical values for all of its fields. Subclasses must implement this; inheritingObject.equals()
is incorrect.- Overrides:
equals
in classjava.lang.Object
- Parameters:
other
- object to be compared for equality with this message- Returns:
true
if the specified object is equal to this message
-
hashCode
int hashCode()
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; inheritingObject.hashCode()
is incorrect.- Overrides:
hashCode
in classjava.lang.Object
- Returns:
- the hash code value for this message
- See Also:
Map.hashCode()
-
toString
java.lang.String toString()
Converts the message to a string in protocol buffer text format. This is just a trivial wrapper aroundTextFormat.Printer.printToString(MessageOrBuilder)
.- Overrides:
toString
in classjava.lang.Object
-
newBuilderForType
Message.Builder newBuilderForType()
Description copied from interface:MessageLite
Constructs a new builder for a message of the same type as this message.- Specified by:
newBuilderForType
in interfaceMessageLite
-
toBuilder
Message.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.- Specified by:
toBuilder
in interfaceMessageLite
