FilteredDocument

public FilteredDocument(java.lang.String allowedChars,
                        boolean numericFlag,
                        int maxNumChars)

Constructs a plain text document.

Parameters:

allowedChars - a String of characters allowed to be entered into the document.

numericFlag - true for valid numeric only

maxNumChars - maximum number of chars allowed

FilteredDocument

public FilteredDocument(java.lang.String specialChars,
                        boolean numericFlag,
                        int maxNumChars,
                        boolean allowFlag)

Constructs a plain text document.

Parameters:

specialChars - a String of characters allowed (or not) into the document.

numericFlag - true for valid numeric only

maxNumChars - maximum number of chars allowed

allowFlag - true to allow only the special characters, false to not allow the special characters.

Method Detail

insertString

public void insertString(int insOffs,
                         java.lang.String insStr,
                         javax.swing.text.AttributeSet aSet)
                  throws javax.swing.text.BadLocationException

Inserts data into the document, filtering it along the way.

Parameters:

insOffs - the starting offset (greater than or equal to zero).

insStr - the string to insert (empty and null strings are ignored).

aSet - the attributes for the inserted content.

Throws:

javax.swing.text.BadLocationException - if the given position is not a valid position within the document.

setMaxValueObj

public void setMaxValueObj(java.lang.Comparable obj)

Sets a maximum value to be allowed for numeric entries (only used if the 'numericFlag' is true).

Parameters:

obj - a "maximum" value object that implements the 'Comparable' interface (or null for no maximum).

getMaxValueObj

public java.lang.Comparable getMaxValueObj()

Returns the maximum value to be allowed for numeric entries, or null if no value has been entered.

Returns:

A "maximum" value object that implements the 'Comparable' interface, or null if no maximum.
