FileField

public FileField(FieldImpl field,
                 FileAccessor accessor,
                 int[][] locations)
          throws FieldException,
                 VisADException

Method Detail

getSample

public Data getSample(int index)
               throws VisADException,
                      RemoteException

Description copied from class: FieldImpl

Get the range value at the index-th sample. The actual range value is returned -- not a copy.

This implementation uses FieldImpl.getSample(int, boolean).

Specified by:

getSample in interface Field

Overrides:

getSample in class FieldImpl

Parameters:

index - index of requested range sample

Returns:

Throws:

VisADException

RemoteException

setSample

public void setSample(int index,
                      Data range)
               throws VisADException,
                      RemoteException

Description copied from class: FieldImpl

Set the range value at the index-th sample; makes a local copy

Specified by:

setSample in interface Field

Overrides:

setSample in class FieldImpl

Parameters:

index - index in domain

range - sample at that index

Throws:

VisADException

RemoteException

clone

public Object clone()
             throws CloneNotSupportedException

Clones this instance. This implementation always throws a CloneNotSupportedException.

Overrides:

clone in class FieldImpl

Returns:

A clone of this instance.

Throws:

CloneNotSupportedException - if cloning isn't supported.
