Data Format



 
String              asciiName

String              contents

Description

An unknown text object is used to transport unknown data found in a text file. It is an encapsulated replica of that unknown data. In the usual case, an unknown text object contains an ill-formed object specification. Your file reading program may be designed to transport the data contained in an unknown text object, to validate and convert the data to a specification of a known object, or to discard the data.

An unknown text object may occur in a binary file as well as in a text file.

Parent Hierarchy

Shared, shape.

Parent Objects

Any object that may have a child object may be a parent object to an unknown text object.

Child Objects

None.

Example



 
UnknownText (

    "Sphere"                                     # unknown object type

    "1 0 0      0 1 0       0 0 1       0 0 a"   # illegal specification

)
