Interface RemoteBufferFileHandle
-
- All Superinterfaces:
BufferFileHandle,java.rmi.Remote
public interface RemoteBufferFileHandle extends BufferFileHandle, java.rmi.Remote
RemoteBufferFileHandlefacilitates access to a remote BufferFile via RMI.Methods from
BufferFileHandlemust be re-declared here so they may be properly marshalled for remote invocation via RMI. This became neccessary with an OpenJDK 11.0.6 change made toRemoteObjectInvocationHandler.
