@CheckReturnValue public final class Descriptors extends java.lang.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 callingMessageType.getDescriptor()
, or (given a message object of the type)message.getDescriptorForType()
. Furthermore, each message is associated with aDescriptors.FileDescriptor
for a relevant.proto
file. You can obtain it by callingDescriptor.getFile()
. ADescriptors.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
.
