Static Methods

hashBoolean(boolean b) (deprecated)

protected static int hashBoolean(boolean b)

Deprecated. from v3.0.0-beta-3+, for compatibility with v2.5.0 and v2.6.1 generated code.

Parameter
Name Description
b boolean
Returns
Type Description
int

hashEnum(Internal.EnumLite e) (deprecated)

protected static int hashEnum(Internal.EnumLite e)

Deprecated. from v3.0.0-beta-3+, for compatibility with v2.5.0 and v2.6.1 generated code.

Parameter
Name Description
e Internal.EnumLite
Returns
Type Description
int

hashEnumList(List<? extends Internal.EnumLite> list) (deprecated)

protected static int hashEnumList(List<? extends Internal.EnumLite> list)

Deprecated. from v3.0.0-beta-3+, for compatibility with v2.5.0 and v2.6.1 generated code.

Parameter
Name Description
list List<? extends com.google.protobuf.Internal.EnumLite>
Returns
Type Description
int

hashFields(int hash, Map<Descriptors.FieldDescriptor,Object> map)

protected static int hashFields(int hash, Map<Descriptors.FieldDescriptor,Object> map)

Get a hash code for given fields and values, using the given seed.

Parameters
Name Description
hash int
map Map<FieldDescriptor,Object>
Returns
Type Description
int

hashLong(long n) (deprecated)

protected static int hashLong(long n)

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.

Parameter
Name Description
other Object
Returns
Type Description
boolean
Overrides

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.

Returns
Type Description
List<String>

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.

Returns
Type Description
String

getOneofFieldDescriptor(Descriptors.OneofDescriptor oneof)

public Descriptors.FieldDescriptor getOneofFieldDescriptor(Descriptors.OneofDescriptor oneof)

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

Parameter
Name Description
oneof Descriptors.OneofDescriptor
Returns
Type Description
Descriptors.FieldDescriptor

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.

Returns
Type Description
int

hasOneof(Descriptors.OneofDescriptor oneof)

public boolean hasOneof(Descriptors.OneofDescriptor oneof)

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

Parameter
Name Description
oneof Descriptors.OneofDescriptor
Returns
Type Description
boolean

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.

Returns
Type Description
int
Overrides

isInitialized()

public boolean isInitialized()

Returns true if all required fields in the message and all embedded messages are set, false otherwise.

See also: MessageOrBuilder#getInitializationErrorString()

Returns
Type Description
boolean

newBuilderForType(AbstractMessage.BuilderParent parent)

protected Message.Builder newBuilderForType(AbstractMessage.BuilderParent parent)

Create a nested builder.

Parameter
Name Description
parent AbstractMessage.BuilderParent
Returns
Type Description
Message.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).

Returns
Type Description
String
Overrides

writeTo(CodedOutputStream output)

public void writeTo(CodedOutputStream output)

Serializes the message and writes it to output. This does not flush or close the stream.

Parameter
Name Description
output CodedOutputStream
Exceptions
Type Description
IOException
