Interface RemoteBufferFileHandle

All Superinterfaces:

BufferFileHandle, Remote

public interface RemoteBufferFileHandle
extends BufferFileHandle, Remote

RemoteBufferFileHandle facilitates access to a remote BufferFile via RMI.

Methods from BufferFileHandle must 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 to RemoteObjectInvocationHandler.
