Constructor Detail

NumericDocument

public NumericDocument(int b,
                       String s)

Constructs a new NumericDocument.

Parameters:

b - The radix in which the numeric content is represented.

s - The initial content of the document.

Method Detail

insertString

public void insertString(int offs,
                         String str,
                         AttributeSet a)
                  throws BadLocationException

Inserts the given String into the document, removing any illegal characters.

Specified by:

insertString in interface Document

Overrides:

insertString in class PlainDocument

Parameters:

offs - The offset at which the String is inserted.

str - The String to be inserted.

a - The attributes for the inserted content.

Throws:

BadLocationException - If offs does not represent a valid insertion location.

isModified

public boolean isModified()

Returns true iff this NumericDocument has been modified since its creation.

remove

public void remove(int offs,
                   int len)
            throws BadLocationException

Removes the specified substring from this NumericDocument. If the content has not been modified since its creation, the removal is suppressed. This forces the first modification to be an insertion, which in fact replaces any content entirely.

Specified by:

remove in interface Document

Overrides:

remove in class AbstractDocument

Throws:

BadLocationException - If the given remove position is not a valid position within the document.
