public abstract class AbstractMessage extends AbstractMessageLite implements Message
A partial implementation of the Message interface which implements as many methods of
that interface as possible in terms of other methods.

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()
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
newBuilderForType(AbstractMessage.BuilderParent parent)
protected Message.Builder newBuilderForType(AbstractMessage.BuilderParent parent)
Parameter
Returns
toString()
public final String toString()
Returns
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.
