All Implemented Interfaces:

Netcdf

public class RemoteNetcdf

extends AbstractNetcdf

A concrete implementation of the Netcdf interface, this class uses java rmi to access a remote Netcdf.

See Also:

Netcdf

Constructor Summary

RemoteNetcdf(NetcdfRemoteProxy remote)
Given a NetcdfRemoteProxy, construct a RemoteNetcdf.

RemoteNetcdf(java.lang.String remoteHostName, java.lang.String dataSetName)
Open up a remote Netcdf by name.

Constructor Detail

RemoteNetcdf

public RemoteNetcdf(NetcdfRemoteProxy remote)
             throws java.rmi.RemoteException

Given a NetcdfRemoteProxy, construct a RemoteNetcdf. The NetcdfRemoteProxy would be obtained from a directory service like NetcdfService.

RemoteNetcdf

public RemoteNetcdf(java.lang.String remoteHostName,
                    java.lang.String dataSetName)
             throws java.rmi.RemoteException,
                    java.rmi.NotBoundException,
                    java.net.MalformedURLException

Open up a remote Netcdf by name. The remote host needs to be running a NetcdfService which exports the data set.

Parameters:

remoteHostName - String host name or dotted quad

dataSetName - String name of the remote Netcdf

Method Detail

getNetcdfService

public static NetcdfService getNetcdfService(java.lang.String remoteHostName)
                                      throws java.rmi.RemoteException,
                                             java.rmi.NotBoundException,
                                             java.net.MalformedURLException

Get remote dataset directory service from a given host. Convience function which wraps java.rmi.Naming.lookup().

Parameters:

remoteHostName - String host name or dotted quad

Returns:

NetcdfService

close

public void close()
           throws java.rmi.RemoteException

Indicate that you are done with this remote Netcdf. Allows the service to free resources. We name this method close for symmetry with NetcdfFile. You do not have to call this. RMI runtime will eventually (~10 minutes?) call NetcdfRemoteProxyImpl.unreferenced() and accomplish the same thing.

NetcdfRemoteProxy.release()

ioFactory

protected Accessor ioFactory(ProtoVariable proto)
                      throws java.lang.reflect.InvocationTargetException

Description copied from class: AbstractNetcdf

Used when creating variables to populate this. Override in your implementation to provide the correct i/o functionality.

Overrides:

ioFactory in class AbstractNetcdf

finalize

protected void finalize()
                 throws java.lang.Throwable

Ensures that the remote resources associated with this are released when there are no more references to it.

Overrides:

finalize in class java.lang.Object
