The I18n Search Format property editor sets the POSIX regular expression used by the Internationalization wizard and the Internationalize command to identify all strings that should not be internationalized. The Internationalize wizard and command convert all strings that do not match this format into internationalized strings.
By default, this setting returns all strings that are in getString and getBundle method calls. If you append //NOI18N to the regular expression, the IDE will also skip any row that contains a //NOI18N comment.
To open the I18n Search Format property editor, choose Tools Options
from the main window, expand the Editing node, and select the Internationalization.
Then click the ellipsis (...) button for the I18n Search Format property.
You can use the Non-Internationalization Regular Expression Format combo box to choose from one of the IDE's preset regular expressions or write your own. The Arguments section contains a list of variables that you can use in your regular expression.
