GeneratedMessageV3

public abstract static class GeneratedMessageV3.ExtendableMessage<MessageType extends GeneratedMessageV3.ExtendableMessage>
extends GeneratedMessageV3
implements GeneratedMessageV3.ExtendableMessageOrBuilder<MessageType>

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 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 = getFoo();
 int i = foo.getExtension(MyProto.bar);

getExtensionFields

protected Map<Descriptors.FieldDescriptor,Object> getExtensionFields()

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

getAllFieldsRaw

public Map<Descriptors.FieldDescriptor,Object> getAllFieldsRaw()

Description copied from class: GeneratedMessageV3

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 GeneratedMessageV3.getFieldRaw(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.

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

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

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

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
