Compares the specified object with this message for equality.Returns a list of field paths (e.g.Returns a comma-delimited list of required fields which are not set in this message object.TODO(jieluo): Clear it when all subclasses have implemented this method.int
Get the number of bytes required to encode this message.int

Method Details
-
isInitialized
public boolean isInitialized()Description copied from interface:MessageLiteOrBuilder
Returns true if all required fields in the message and all embedded messages are set, false otherwise.- Specified by:
isInitialized
in interfaceMessageLiteOrBuilder
-
findInitializationErrors
Description copied from interface:MessageOrBuilder
Returns a list of field paths (e.g. "foo.bar.baz") of required fields which are not set in this message. You should callMessageLiteOrBuilder.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.- Specified by:
findInitializationErrors
in interfaceMessageOrBuilder
-
getInitializationErrorString
Description copied from interface:MessageOrBuilder
Returns a comma-delimited list of required fields which are not set in this message object. You should callMessageLiteOrBuilder.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.- Specified by:
getInitializationErrorString
in interfaceMessageOrBuilder
-
hasOneof
TODO(jieluo): Clear it when all subclasses have implemented this method.- Specified by:
hasOneof
in interfaceMessageOrBuilder
-
getOneofFieldDescriptor
TODO(jieluo): Clear it when all subclasses have implemented this method.- Specified by:
getOneofFieldDescriptor
in interfaceMessageOrBuilder
-
toString
Description copied from interface:Message
Converts the message to a string in protocol buffer text format. This is just a trivial wrapper aroundTextFormat.printToString(MessageOrBuilder)
. -
writeTo
Description copied from interface:MessageLite
Serializes the message and writes it tooutput
. This does not flush or close the stream.- Specified by:
writeTo
in interfaceMessageLite
- Throws:
IOException
-
getSerializedSize
public int getSerializedSize()Description copied from interface:MessageLite
Get the number of bytes required to encode this message. The result is only computed on the first call and memoized after that.- Specified by:
getSerializedSize
in interfaceMessageLite
-
equals
Description copied from interface:Message
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. -
hashCode
public int hashCode()Description copied from interface:Message
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. -
hashFields
Get a hash code for given fields and values, using the given seed.
