Interface Message

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 to it methods that are not available in the "lite" runtime. The biggest added features are introspection and reflection -- i.e., getting descriptors for the message type and accessing the field values dynamically.

Methods

equals(Object other)

public abstract boolean equals(Object other)

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.

Parameter
NameDescription
otherObject

object to be compared for equality with this message

Returns
TypeDescription
boolean

true if the specified object is equal to this message

Overrides

getParserForType()

public abstract Parser<? extends Message> getParserForType()

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

Returns
TypeDescription
Parser<? extends com.google.protobuf.Message>

hashCode()

public abstract 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; inheriting Object.hashCode() is incorrect.

Returns
TypeDescription
int

the hash code value for this message

Overrides

newBuilderForType()

public abstract Message.Builder newBuilderForType()

Constructs a new builder for a message of the same type as this message.

Returns
TypeDescription
Message.Builder

toBuilder()

public abstract Message.Builder toBuilder()

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

Returns
TypeDescription
Message.Builder

toString()

public abstract String toString()

Converts the message to a string in protocol buffer text format. This is just a trivial wrapper around TextFormat.Printer#printToString(MessageOrBuilder).

Returns
TypeDescription
String
