Description
As a replace is typically seen as two edits, a remove than an insert, this can confuse the formatter and result in odd behavior. For example if you are editing a number, select all the text and replace it with a legal number often times it won't let you as the initial removal results in a bogus value.

EVALUATION The following will be added to AbstractDocument: /** * Deletes the region of text from <code>offset</code> to * <code>offset + length</code>, and replaces it with <code>text</code>. * It is up to the implementation as to how this is implemented, some * implementations may treat this as two distinct operations: a remove * followed by an insert, others may treat the replace as one atomic * operation. * * @param offset Location in Document * @param length Length of text to delete * @param text Text to insert, null indicates no text to insert * @param attrs AttributeSet indicating attributes of inserted text, null * is legal, and typically treated as an empty attributeset, * but exact interpretation is left to the subclass * @exception BadLocationException the given position is not a valid * position within the document * @since 1.4 */ public void replace(int offset, int length, String text, AttributeSet attrs) throws BadLocationException; Similarly javax.swing.text.DocumentFilter will get (there is no @since 1.4 here as DocumentFilter is new in 1.4): /** * Invoked prior to replacing a region of text in the * specified Document. Subclasses that want to conditionally allow * replace should override this and only call supers implementation as * necessary, or call directly into the FilterBypass. * * @param fb FilterBypass that can be used to mutate Document * @param offset Location in Document * @param length Length of text to delete * @param text Text to insert, null indicates no text to insert * @param attrs AttributeSet indicating attributes of inserted text, * null is legal. * @exception BadLocationException the given insert position is not a * valid position within the document */ public void replace(FilterBypass fb, int offset, int length, String text, AttributeSet attrs) throws BadLocationException; And javax.swing.text.DocumentFilter.FilterBypass will get: /** * Deletes the region of text from <code>offset</code> to * <code>offset + length</code>, and replaces it with * <code>text</code>. * * @param offset Location in Document * @param length Length of text to delete * @param text Text to insert, null indicates no text to insert * @param attrs AttributeSet indicating attributes of inserted text, * null is legal. * @exception BadLocationException the given insert is not a * valid position within the document */ public abstract void replace(int offset, int length, String string, AttributeSet attrs) throws BadLocationException; scott.violet@eng 2001-04-24
