Class GeneratedMessage.ExtendableBuilder<MessageType,BuilderType> (3.19.4)

public abstract static class GeneratedMessage.ExtendableBuilder<MessageType,BuilderType> 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 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 Map<Descriptors.FieldDescriptor,Object> getAllFields()

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.

Returns
Type	Description
Map<FieldDescriptor,Object>

Overrides

GeneratedMessage.Builder<BuilderType>.getAllFields()

getField(Descriptors.FieldDescriptor field)

public Object getField(Descriptors.FieldDescriptor field)

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.

Parameter
Name	Description
field	Descriptors.FieldDescriptor

Returns
Type	Description
Object

Overrides

GeneratedMessage.Builder<BuilderType>.getField(Descriptors.FieldDescriptor field)

getRepeatedField(Descriptors.FieldDescriptor field, int index)

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

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.

Overrides

GeneratedMessage.Builder<BuilderType>.getRepeatedField(Descriptors.FieldDescriptor field, int index)

getRepeatedFieldCount(Descriptors.FieldDescriptor field)
