public abstract class DataImpl
extends ThingImpl
implements Data

DataImpl is the superclass for VisAD's data hierarchy, inheriting the Data interface. Data objects are immutable except for the range values of Field objects.

VisAD Data objects are finite approximations to math objects that include scalars, tuples (i.e., n-dimensional vectors), functions, and certain forms of sets. Hence, all Data objects possess a MathType, which identifies the corresponding concept and is not a synonym for the Data class, even though the class names for a Data object and its corresponding MathType object (Set and SetType, e.g.) may be similar. In order to approximate their corresponding mathematical entities, Data objects may use text strings or finite representations of real numbers. Also, any Data object may take the value 'missing', and any sub-object of a Data object may take the value 'missing'.

All of the Java arithmetical operations are defined for Data objects, to the extent that they make sense for the types involved.

Returns:

for DataImpl return clone(), and for RemoteDataImpl return clone() inherited from UnicastRemoteObject

clone

Clones this instance. Information on the parent object of this instance is not cloned, so -- following the general contract of the clone() method -- subclasses should not test for equality of the parent object in any equals(Object) method.

This implementation never throws CloneNotSupportedException.

Overrides:

clone in class ThingImpl

Returns:

A clone of this instance.

Throws:

CloneNotSupportedException - if cloning isn't supported.

toString

public String toString()

Overrides:

toString in class Object

Returns:

a String representation of this
