Returns a deep copy of this instance.

toXMLString

public String toXMLString()

Description copied from interface: Displayable

Returns a well-formed XML string representing the Displayable. The Displayable should be reconstructable via this representation. Therefore it must at least include the type of Displayable (classname) and a representation of its value. PROBABLE FUTURE DESIGN: The Displayables themselves will provide a method to reconstruct their value from the XML representation they provided.

Specified by:

toXMLString in interface Displayable

Overrides:

toXMLString in class AbstractAttribute

Returns:

string holding an XML representation of this Displayable
