Constructor Detail

NfsCommitResponse

public NfsCommitResponse(int nfsVersion)

Creates the response, as specified by RFC 1813 (https://tools.ietf.org/html/rfc1813).

Procedure COMMIT forces or flushes data to stable storage that was previously written with a WRITE procedure call with the stable field set to UNSTABLE.

Parameters:

nfsVersion - The NFS version number. This is ignored for now, as only NFSv3 is supported, but is included to allow future support for other versions.

Method Detail

unmarshalling

public void unmarshalling(Xdr xdr)
                   throws RpcException

Description copied from class: RpcResponse

Load this structure from the response data, as specified by RFC 1831 (https://tools.ietf.org/html/rfc1831).

Overrides:

unmarshalling in class NfsResponseBase

Parameters:

xdr - The xdr response data.

Throws:

RpcException

getVerf

public long getVerf()

Returns:

A cookie that the client can use to determine whether the server has rebooted between a call to WRITE and a subsequent call to COMMIT. This cookie must be consistent during a single boot session and must be unique between instances of the NFS version 3 protocol server where uncommitted data may be lost.

getFileWccData

public NfsWccData getFileWccData()

Returns:

Weak cache consistency data for the file.
