Methods
equals(Object other)
public
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.
findInitializationErrors()
public
List<String>
findInitializationErrors
()
Returns a list of field paths (e.g. "foo.bar.baz") of required fields which are not set in this message. You should call MessageLiteOrBuilder#isInitialized() first to check if there are any missing fields, as that method is likely to be much faster than this one even when the message is fully-initialized.
getInitializationErrorString()
public
String
getInitializationErrorString
()
Returns a comma-delimited list of required fields which are not set in this message object. You should call MessageLiteOrBuilder#isInitialized() first to check if there are any missing fields, as that method is likely to be much faster than this one even when the message is fully-initialized.
getOneofFieldDescriptor(Descriptors.OneofDescriptor oneof)
public
Descriptors
.
FieldDescriptor
getOneofFieldDescriptor
(
Descriptors
.
OneofDescriptor
oneof
)
TODO(jieluo): Clear it when all subclasses have implemented this method.
getSerializedSize()
public
int
getSerializedSize
()
Get the number of bytes required to encode this message. The result is only computed on the first call and memoized after that.
If this message requires more than Integer.MAX_VALUE bytes to encode, the return value will be smaller than the actual number of bytes required and might be negative.
hasOneof(Descriptors.OneofDescriptor oneof)
public
boolean
hasOneof
(
Descriptors
.
OneofDescriptor
oneof
)
TODO(jieluo): Clear it when all subclasses have implemented this method.
hashCode()
public
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.
isInitialized()
public
boolean
isInitialized
()
Returns true if all required fields in the message and all embedded messages are set, false otherwise.
newBuilderForType(AbstractMessage.BuilderParent parent)
protected
Message
.
Builder
newBuilderForType
(
AbstractMessage
.
BuilderParent
parent
)
Create a nested builder.
toString()
public
final
String
toString
()
Converts the message to a string in protocol buffer text format. This is just a trivial wrapper around TextFormat.Printer#printToString(MessageOrBuilder) .
writeTo(CodedOutputStream output)
public
void
writeTo
(
CodedOutputStream
output
)
Serializes the message and writes it to output
. This does not flush or close the
stream.
