All Implemented Interfaces:

NfsRequest

public class Nfs3ReadlinkRequest
extends NfsReadlinkRequest

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

This method reads the data associated with a symbolic link. The data is an ASCII string that is opaque to the server. That is, whether created by the NFS version 3 protocol software from a client or created locally on the server, the data in a symbolic link is not interpreted when created, but is simply stored.

A symbolic link is nominally a pointer to another file. The data is not necessarily interpreted by the server, just stored in the file. It is possible for a client implementation to store a path name that is not meaningful to the server operating system in a symbolic link. A READLINK operation returns the data to the client for interpretation. If different implementations want to share access to symbolic links, then they must agree on the interpretation of the data in the symbolic link.

Nfs3ReadlinkRequest

public Nfs3ReadlinkRequest(byte[] fileHandle,
                           Credential credential)
                    throws java.io.FileNotFoundException

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

This method reads the data associated with a symbolic link. The data is an ASCII string that is opaque to the server. That is, whether created by the NFS version 3 protocol software from a client or created locally on the server, the data in a symbolic link is not interpreted when created, but is simply stored.

A symbolic link is nominally a pointer to another file. The data is not necessarily interpreted by the server, just stored in the file. It is possible for a client implementation to store a path name that is not meaningful to the server operating system in a symbolic link. A READLINK operation returns the data to the client for interpretation. If different implementations want to share access to symbolic links, then they must agree on the interpretation of the data in the symbolic link.

Parameters:

fileHandle - the fileHandle for the symbolic link

credential - The credential used for RPC authentication.

Throws:

java.io.FileNotFoundException
