NfsReaddirRequest

public NfsReaddirRequest(byte[] fileHandle,
 long cookie,
 long cookieverf,
 int count,
 Credential credential,
 int nfsVersion)
                  throws FileNotFoundException

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

Procedure READDIR retrieves a variable number of entries, in sequence, from a directory and returns the name and file identifier for each, with information to allow the client to request additional directory entries in a subsequent READDIR request.

Parameters:

fileHandle - The file handle for the directory to be read.

cookie - This should be set to 0 in the first request to read the directory. On subsequent requests, it should be a cookie as returned by the server.

cookieverf - This should be set to 0 in the first request to read the directory. On subsequent requests, it should be a cookieverf as returned by the server. The cookieverf must match that returned by the READDIR in which the cookie was acquired.

count - The maximum size of the READDIR3resok structure, in bytes. The size must include all XDR overhead. The server is free to return less than count bytes of data.

credential - The credential used for RPC authentication.

nfsVersion - The NFS version number

Throws:

FileNotFoundException
