- GeneratedMessageV3
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
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 callingMessageOrBuilder.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:

getField
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:

getFieldBuilder
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) 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 is returned. Otherwise, a new field builder is created and returned. The original message field (if one exists) is merged into the field builder, which is then nested into its parent builder.

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 theMessage.Builder.setField(Descriptors.FieldDescriptor, Object)
,Message.Builder.setRepeatedField(Descriptors.FieldDescriptor, int, Object)
