Method Detail

forDescriptor

public static ProtoDynamicMessageSchema forDescriptor(ProtoDomain domain,
                                                      java.lang.String messageName)

Create a new ProtoDynamicMessageSchema from a ProtoDomain and for a message. The message need to be in the domain and needs to be the fully qualified name.

forDescriptor

public static ProtoDynamicMessageSchema<com.google.protobuf.DynamicMessage> forDescriptor(ProtoDomain domain,
                                                                                          com.google.protobuf.Descriptors.Descriptor descriptor)

Create a new ProtoDynamicMessageSchema from a ProtoDomain and for a descriptor. The descriptor is only used for it's name, that name will be used for a search in the domain.
