All Implemented Interfaces:

Message, MessageLite, MessageLiteOrBuilder, MessageOrBuilder, java.io.Serializable

Direct Known Subclasses:

DescriptorProtos.DescriptorProto, DescriptorProtos.DescriptorProto.ExtensionRange, DescriptorProtos.EnumDescriptorProto, DescriptorProtos.EnumValueDescriptorProto, DescriptorProtos.FieldDescriptorProto, DescriptorProtos.FileDescriptorProto, DescriptorProtos.FileDescriptorSet, DescriptorProtos.MethodDescriptorProto, DescriptorProtos.ServiceDescriptorProto, DescriptorProtos.SourceCodeInfo, DescriptorProtos.SourceCodeInfo.Location, DescriptorProtos.UninterpretedOption, DescriptorProtos.UninterpretedOption.NamePart, GeneratedMessage.ExtendableMessage

public abstract class GeneratedMessage
extends AbstractMessage
implements java.io.Serializable

All generated protocol message classes extend this class. This class implements most of the Message and Builder interfaces using Java reflection. Users can ignore this class and pretend that generated messages implement the Message interface directly.

Field Detail

alwaysUseFieldBuilders

protected static boolean alwaysUseFieldBuilders

For testing. Allows a test to disable the optimization that avoids using field builders for nested messages until they are requested. By disabling this optimization, existing tests can be reused to test the field builders.

Method Detail

getParserForType

public Parser<? extends Message> getParserForType()

Description copied from interface: MessageLite

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

Specified by:

getParserForType in interface Message

Specified by:

getParserForType in interface MessageLite

internalGetFieldAccessorTable

protected abstract GeneratedMessage.FieldAccessorTable internalGetFieldAccessorTable()

Get the FieldAccessorTable for this type. We can't have the message class pass this in to the constructor because of bootstrapping trouble with DescriptorProtos.

getDescriptorForType

public Descriptors.Descriptor getDescriptorForType()

Description copied from interface: MessageOrBuilder

Get the message's type's descriptor. This differs from the getDescriptor() method of generated message classes in that this method is an abstract method of the Message interface whereas getDescriptor() is a static method of a specific class. They return the same thing.

Specified by:

getDescriptorForType in interface MessageOrBuilder

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.

See also: MessageOrBuilder.getInitializationErrorString()

Specified by:

isInitialized in interface MessageLiteOrBuilder

Overrides:

isInitialized in class AbstractMessage

getAllFields

public java.util.Map<Descriptors.FieldDescriptor,java.lang.Object> getAllFields()

Description copied from interface: MessageOrBuilder

Returns a collection of all the fields in this message which are set and their corresponding values. A singular ("required" or "optional") field is set iff hasField() returns true for that field. A "repeated" field is set iff getRepeatedFieldSize() is greater than zero. The values are exactly what would be returned by calling MessageOrBuilder.getField(Descriptors.FieldDescriptor) for each field. The map is guaranteed to be a sorted map, so iterating over it will return fields in order by field number.
If this is for a builder, the returned map may or may not reflect future changes to the builder. Either way, the returned map is itself unmodifiable.

Specified by:

getAllFields in interface MessageOrBuilder

hasField

public boolean hasField(Descriptors.FieldDescriptor field)

Description copied from interface: MessageOrBuilder

Returns true if the given field is set. This is exactly equivalent to calling the generated "has" accessor method corresponding to the field.

Specified by:

hasField in interface MessageOrBuilder

getField

public java.lang.Object getField(Descriptors.FieldDescriptor field)

Description copied from interface: MessageOrBuilder

Obtains the value of the given field, or the default value if it is not set. For primitive fields, the boxed primitive value is returned. For enum fields, the EnumValueDescriptor for the value is returned. For embedded message fields, the sub-message is returned. For repeated fields, a java.util.List is returned.

Specified by:

getField in interface MessageOrBuilder

getRepeatedFieldCount

public int getRepeatedFieldCount(Descriptors.FieldDescriptor field)

Description copied from interface: MessageOrBuilder

Gets the number of elements of a repeated field. This is exactly equivalent to calling the generated "Count" accessor method corresponding to the field.

Specified by:

getRepeatedFieldCount in interface MessageOrBuilder

getRepeatedField

public java.lang.Object getRepeatedField(Descriptors.FieldDescriptor field,
                                         int index)

Description copied from interface: MessageOrBuilder

Gets an element of a repeated field. For primitive fields, the boxed primitive value is returned. For enum fields, the EnumValueDescriptor for the value is returned. For embedded message fields, the sub-message is returned.

Specified by:

getRepeatedField in interface MessageOrBuilder

getUnknownFields

public UnknownFieldSet getUnknownFields()

Description copied from interface: MessageOrBuilder

Get the UnknownFieldSet for this message.

Specified by:

getUnknownFields in interface MessageOrBuilder

parseUnknownField

protected boolean parseUnknownField(CodedInputStream input,
                                    UnknownFieldSet.Builder unknownFields,
                                    ExtensionRegistryLite extensionRegistry,
                                    int tag)
                             throws java.io.IOException

Called by subclasses to parse an unknown field.

Returns:

true unless the tag is an end-group tag.

Throws:

java.io.IOException

makeExtensionsImmutable

protected void makeExtensionsImmutable()

Used by parsing constructors in generated classes.

newBuilderForType

protected abstract Message.Builder newBuilderForType(GeneratedMessage.BuilderParent parent)

newMessageScopedGeneratedExtension

                                                                                                                                                Message defaultInstance)

For use by generated code only.

newFileScopedGeneratedExtension

public static <ContainingType extends Message,Type> GeneratedMessage.GeneratedExtension<ContainingType,Type> newFileScopedGeneratedExtension(java.lang.Class singularType,
                                                                                                                                             Message defaultInstance)

For use by generated code only.

writeReplace

protected java.lang.Object writeReplace()
                                 throws java.io.ObjectStreamException

Replaces this object in the output stream with a serialized form. Part of Java's serialization magic. Generated sub-classes must override this method by calling return super.writeReplace();

Returns:

a SerializedForm of this message

Throws:

java.io.ObjectStreamException
