NoDGC.MarshalContext(NoDGC dgc)

Method Detail

localReferenceMarshaled

public java.lang.Object localReferenceMarshaled(SingleRemoteClientRef ref,
                                                RemoteServerRef dgcObject)

Description copied from class: DGCMarshalContext

Called by a remote reference while it is serialized to a marshal stream and the dgc object for the resulting object is a local DGC.

Specified by:

localReferenceMarshaled in class DGCMarshalContext

Returns:

a new dgcInfo object

remoteReferenceMarshaled

public java.lang.Object remoteReferenceMarshaled(SingleRemoteClientRef ref)

Description copied from class: DGCMarshalContext

Called by a remote reference while it is serialized and the dgc object for the resulting object is no local DGC.

Specified by:

remoteReferenceMarshaled in class DGCMarshalContext

Returns:

a new dgcInfo object

done

public boolean done()

Description copied from class: DGCMarshalContext

Called when all objects of a call are marshaled to the stream.

Specified by:

done in class DGCMarshalContext

Returns:

whether the DGC algorithm needs a notification about the successful arrival of the remote reference at the remote address space. A reference has arrived successfully, if it has connected to the garbage collector on the remote side.

reset

public void reset()

Description copied from class: DGCMarshalContext

Reset context for reuse

Specified by:

reset in class DGCMarshalContext

proxyRequired

public boolean proxyRequired(SingleRemoteClientRef ref)

Description copied from class: DGCMarshalContext

Decides whether a proxy is required for DGC purpose only. If a remote reference is marshaled to another VM, and the server implementation is proven to be accessible from that VM, the DGC can still request to build a proxy.

Specified by:

proxyRequired in class DGCMarshalContext
