Constructor Detail

Nfs3File

public Nfs3File(Nfs3 nfs,
                java.lang.String path)
         throws java.io.IOException

The basic constructor.

Parameters:

nfs - The supporting NFS client.

path - The full path of the file, starting with the mount point.

Throws:

java.io.IOException

Nfs3File

public Nfs3File(Nfs3 nfs,
                java.lang.String path,
                LinkTracker<Nfs3,Nfs3File> linkTracker)
         throws java.io.IOException

The basic constructor plus link tracking.

Parameters:

nfs - The supporting NFS client.

path - The full path of the file, starting with the mount point.

linkTracker - The tracker to use. This must be passed so that monitoring is continued until the link resolves to a file that is not a symbolic link.

Throws:

java.io.IOException

Nfs3File

public Nfs3File(Nfs3File parent,
                java.lang.String child)
         throws java.io.IOException

The most efficient constructor if the parent file already exists.

Parameters:

parent - The parent file, stored to reduce lookup overhead

child - The short name of the file, starting from the parent path.

Throws:

java.io.IOException

Method Detail
