Class GeneratedMessageV3.ExtendableMessage<MessageType> (3.19.4)

Generated message classes 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. "has", "get", and "getCount" -- but for extensions. The extensions are identified using instances of the class 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 = getFoo(); int i = foo.getExtension(MyProto.bar);

Check if a singular extension is present.

Check if a singular extension is present.

Check if a singular extension is present.

Called by subclasses to check if all extensions are initialized.

Called by subclasses to compute the size of extensions.

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 getRepeatedFieldCount() is greater than zero. The values are exactly what would be returned by calling #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.

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.

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.

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

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

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

Used by parsing constructors in generated classes.

Called by subclasses to parse an unknown field.

Delegates to parseUnknownField. This method is obsolete, but we must retain it for compatibility with older generated code.
