Descriptors

```
public final class Descriptors
extends Object
```
Contains a collection of classes which describe protocol message types. Every message type has a Descriptors.Descriptor, which lists all its fields and other information about a type. You can get a message type's descriptor by calling MessageType.getDescriptor(), or (given a message object of the type) message.getDescriptorForType(). Furthermore, each message is associated with a Descriptors.FileDescriptor for a relevant .proto file. You can obtain it by calling Descriptor.getFile(). A Descriptors.FileDescriptor contains descriptors for all the messages defined in that file, and file descriptors for all the imported .proto files. Descriptors are built from DescriptorProtos, as defined in google/protobuf/descriptor.proto.
