Detailed Description

This class represents a data field from a file read by an instance of a class implementing DataReader.

Constructor & Destructor Documentation

◆ DataField() [1/2]

DataField	(	String	label,
		Object	data
	)

Constructor.

Creates a field named label of value data.

Parameters

label	name of the field
data	value of the field

◆ DataField() [2/2]

DataField	(	String	label,
		Object	data,
