public abstract static class GeneratedMessageV3.ExtendableBuilder<MessageType extends GeneratedMessageV3.ExtendableMessage,BuilderType extends GeneratedMessageV3.ExtendableBuilder<MessageType,BuilderType>>
extends GeneratedMessageV3.Builder<BuilderType>
implements GeneratedMessageV3.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();

extensionsAreInitialized

protected boolean extensionsAreInitialized()

Called by subclasses to check if all extensions are initialized.

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.

getAllFields

public Map<Descriptors.FieldDescriptor,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 getRepeatedFieldCount() 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 GeneratedMessageV3.Builder<BuilderType extends GeneratedMessageV3.ExtendableBuilder<MessageType,BuilderType>>

getField

public 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

Overrides:

getField in class GeneratedMessageV3.Builder<BuilderType extends GeneratedMessageV3.ExtendableBuilder<MessageType,BuilderType>>

getFieldBuilder

public Message.Builder getFieldBuilder(Descriptors.FieldDescriptor field)

Description copied from interface: Message.Builder

Get a nested builder instance for the given field.

Normally, we hold a reference to the immutable message object for the message type field. Some implementations(the generated message builders), however, can also hold a reference to the builder object (a nested builder) for the field.

If the field is already backed up by a nested builder, the nested builder will be returned. Otherwise, a new field builder will be created and returned. The original message field (if exist) will be merged into the field builder, which will then be nested into its parent builder.

NOTE: implementations that do not support nested builders will throw UnsupportedOperationException.

Specified by:

getFieldBuilder in interface Message.Builder

Overrides:

getFieldBuilder in class GeneratedMessageV3.Builder<BuilderType extends GeneratedMessageV3.ExtendableBuilder<MessageType,BuilderType>>

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

Overrides:

getRepeatedFieldCount in class GeneratedMessageV3.Builder<BuilderType extends GeneratedMessageV3.ExtendableBuilder<MessageType,BuilderType>>

getRepeatedField

public 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

Overrides:

getRepeatedField in class GeneratedMessageV3.Builder<BuilderType extends GeneratedMessageV3.ExtendableBuilder<MessageType,BuilderType>>

getRepeatedFieldBuilder

public Message.Builder getRepeatedFieldBuilder(Descriptors.FieldDescriptor field,
                                               int index)

Description copied from interface: Message.Builder

Get a nested builder instance for the given repeated field instance.

Normally, we hold a reference to the immutable message object for the message type field. Some implementations(the generated message builders), however, can also hold a reference to the builder object (a nested builder) for the field.

If the field is already backed up by a nested builder, the nested builder will be returned. Otherwise, a new field builder will be created and returned. The original message field (if exist) will be merged into the field builder, which will then be nested into its parent builder.

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

Overrides:

hasField in class GeneratedMessageV3.Builder<BuilderType extends GeneratedMessageV3.ExtendableBuilder<MessageType,BuilderType>>

setField

public BuilderType setField(Descriptors.FieldDescriptor field,
                            Object value)

Description copied from interface: Message.Builder

Sets a field to the given value. The value must be of the correct type for this field, i.e. the same type that MessageOrBuilder.getField(Descriptors.FieldDescriptor) would return.

Specified by:

setField in interface Message.Builder

Overrides:

setField in class GeneratedMessageV3.Builder<BuilderType extends GeneratedMessageV3.ExtendableBuilder<MessageType,BuilderType>>

clearField

public BuilderType clearField(Descriptors.FieldDescriptor field)

Description copied from interface: Message.Builder

Clears the field. This is exactly equivalent to calling the generated "clear" accessor method corresponding to the field.

Specified by:

clearField in interface Message.Builder

Overrides:

clearField in class GeneratedMessageV3.Builder<BuilderType extends GeneratedMessageV3.ExtendableBuilder<MessageType,BuilderType>>

setRepeatedField

                                    Object value)

Description copied from interface: Message.Builder

Sets an element of a repeated field to the given value. The value must be of the correct type for this field, i.e. the same type that MessageOrBuilder.getRepeatedField(Descriptors.FieldDescriptor,int) would return.

Specified by:

setRepeatedField in interface Message.Builder

Overrides:

setRepeatedField in class GeneratedMessageV3.Builder<BuilderType extends GeneratedMessageV3.ExtendableBuilder<MessageType,BuilderType>>

addRepeatedField in interface Message.Builder

Overrides:

addRepeatedField in class GeneratedMessageV3.Builder<BuilderType extends GeneratedMessageV3.ExtendableBuilder<MessageType,BuilderType>>

newBuilderForField

public Message.Builder newBuilderForField(Descriptors.FieldDescriptor field)

Description copied from interface: Message.Builder

Create a builder for messages of the appropriate type for the given field. The builder is NOT nested in the current builder. However, messages built with the builder can then be passed to the Message.Builder.setField(Descriptors.FieldDescriptor, Object), Message.Builder.setRepeatedField(Descriptors.FieldDescriptor, int, Object), or Message.Builder.addRepeatedField(Descriptors.FieldDescriptor, Object) method of the current builder.

To obtain a builder nested in the current builder, use Message.Builder.getFieldBuilder(Descriptors.FieldDescriptor) instead.
