Method Detail

getParserForType

public final Parser<MessageType> getParserForType()

Description copied from interface: MessageLite

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

Specified by:

getParserForType in interface MessageLite

getDefaultInstanceForType

public final MessageType getDefaultInstanceForType()

Description copied from interface: MessageLiteOrBuilder

Get an instance of the type with no fields set. Because no fields are set, all getters for singular fields will return default values and repeated fields will appear empty. This may or may not be a singleton. This differs from the getDefaultInstance() method of generated message classes in that this method is an abstract method of the MessageLite interface whereas getDefaultInstance() is a static method of a specific class. They return the same thing.

Specified by:

getDefaultInstanceForType in interface MessageLiteOrBuilder

newBuilderForType

public final BuilderType newBuilderForType()

Description copied from interface: MessageLite

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

Specified by:

newBuilderForType in interface MessageLite

parseUnknownField

protected static boolean parseUnknownField(CodedInputStream input,
                        UnknownFieldSetLite.Builder unknownFields,
                        ExtensionRegistryLite extensionRegistry,
                        int tag)
                                    throws IOException

Called by subclasses to parse an unknown field. For use by generated code only.

Returns:

true unless the tag is an end-group tag.

Throws:

IOException

isInitialized

public final boolean isInitialized()

Description copied from interface: MessageLiteOrBuilder

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

See also: MessageOrBuilder.getInitializationErrorString()

Specified by:

isInitialized in interface MessageLiteOrBuilder

toBuilder

public final BuilderType toBuilder()

Description copied from interface: MessageLite

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

Specified by:

toBuilder in interface MessageLite

dynamicMethod

protected abstract Object dynamicMethod(GeneratedMessageLite.MethodToInvoke method,
                   Object arg0,
                   Object arg1)

A method that implements different types of operations described in GeneratedMessageLite.MethodToInvoke. Theses different kinds of operations are required to implement message-level operations for builders in the runtime. This method bundles those operations to reduce the generated methods count.

• PARSE_PARTIAL_FROM is parameterized with an CodedInputStream and ExtensionRegistryLite. It consumes the input stream, parsing the contents into the returned protocol buffer. If parsing throws an InvalidProtocolBufferException, the implementation wraps it in a RuntimeException
• NEW_INSTANCE returns a new instance of the protocol buffer
• IS_INITIALIZED is parameterized with a Boolean detailing whether to memoize. It returns null for false and the default instance for true. We optionally memoize to support the Builder case, where memoization is not desired.
• NEW_BUILDER returns a BuilderType instance.
• MERGE_FROM is parameterized with a MessageType and merges the fields from that instance into this instance.
• MAKE_IMMUTABLE sets all internal fields to an immutable state.

This method, plus the implementation of the Builder, enables the Builder class to be proguarded away entirely on Android.

For use by generated code only.

protected Object dynamicMethod(GeneratedMessageLite.MethodToInvoke method,
                   Object arg0)

For use by generated code only.
