Hi,

I think I found a small error in the page 495 of EMF Book second
edition. It concerns XMLResource.OPTION_USE_DEPRECATED_METHODS.
The documentation says that default is true, and that we could turn this
option to false to improve deserialization performance. But in the 495
page there is a resource factory implementation example with recommended
options for perfomance, where XMLResource.OPTION_USE_DEPRECATED_METHODS
is set to true.

So is it a mistake or did I miss something ?

BTW the book is great and helpful :)

Best Regards,

Mariot

Mariot,

Yes, that doesn't sound quite right. I've CC'd Dave...

Hi Mariot,

Yup, that is an error in the example. It's one of three known errors so
far:

Page 467 (Section 15.3.1). The second paragraph following the output
fragment (beginning with "Notice that we waited") should be deleted
entirely.

Page 495 (Section 15.5). In the example code, the value of
OPTION_USE_DEPRECATED_METHODS should be Boolean.FALSE. Loading
performance is improved by disabling deprecated methods (they're enabled
by default).

Page 561 (Section 18.3). The value in the second row, last column of
Table 18.2 should be "2007-01-01".

Unfortunately, there have been delays with the publisher getting the
Errata posted on the book's Web site. In the mean time, I decided to put
it up on the Eclipse wiki:

http://wiki.eclipse.org/EMF_Book_Errata

Please feel free to add to the list there if you see any other problems.

Thanks,
Dave
