Class Number_Document

  extended by javax.swing.text.AbstractDocument
      extended by javax.swing.text.PlainDocument
          extended by HiRISE.HiPlan.Utilities.Number_Document
All Implemented Interfaces:
Serializable, Document

public class Number_Document
extends PlainDocument

A PlainDocument that allows only those characters suitable for an English decimal number. These include the ten digits, the decimal point ('.'), the comma (','), the plus sign ('+'), and the minus sign ('-'). All other characters are ignored and never become part of the Number_Document's content.

NOTE: No attempt is made to ensure that the contents of the document form a valid number. The document may read '..+++---,' for example, which is not a valid number but which contains only valid number characters.
