GeneratedMessage

public abstract static class GeneratedMessage.ExtendableBuilder<MessageType extends GeneratedMessage.ExtendableMessage,BuilderType extends GeneratedMessage.ExtendableBuilder>
extends GeneratedMessage.Builder<BuilderType>
implements GeneratedMessage.ExtendableMessageOrBuilder<MessageType>

Generated message builders for message types that contain extension ranges subclass this.

This class implements type-safe accessors for extensions. They implement all the same operations that you can do with normal fields -- e.g. "get", "set", and "add" -- but for extensions. The extensions are identified using instances of the class GeneratedMessage.GeneratedExtension; the protocol compiler generates a static instance of this class for every extension in its input. Through the magic of generics, all is made type-safe.

For example, imagine you have the .proto file:

 option java_class = "MyProto";

 message Foo {
   extensions 1000 to max;
 }

 extend Foo {
   optional int32 bar;
 }
 

Then you might write code like:

 MyProto.Foo foo =
   MyProto.Foo.newBuilder()
     .setExtension(MyProto.bar, 123)
     .build();

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

Overrides:

getAllFields in class GeneratedMessage.Builder<BuilderType extends GeneratedMessage.ExtendableBuilder>

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.

Overrides:

getRepeatedFieldCount in class GeneratedMessage.Builder<BuilderType extends GeneratedMessage.ExtendableBuilder>

getRepeatedField

public java.lang.Object getRepeatedField(Descriptors.FieldDescriptor field,

setRepeatedField

public BuilderType setRepeatedField(Descriptors.FieldDescriptor field,
                                    int index,
