Handy util method for WizardPages

Consider this familiar New Java class wizard.





It has to keep track of the status of the source folder, package, enclosing type, name, ... When ever there is a change in these fields, the WizardPage's status has to be updated. The algorithm goes like this: find the most severe status and update the wizard page with that status. This is a very common operation can be applied to any WizardPage. So I've written a helper method which I usually use it in almost all of the WizardPage I create. Let me know if it can be improved



public static void applyStatus(WizardPage page, IStatus[] statuses) {



IStatus severeStatus = statuses[0];

for (IStatus status : statuses) {

severeStatus = severeStatus.getSeverity() >= status.getSeverity() ? severeStatus : status;

}



String message = severeStatus.getMessage();

switch (severeStatus.getSeverity()) {

case IStatus.OK:

page.setMessage(null, IMessageProvider.NONE);

page.setErrorMessage(null);

break;

case IStatus.WARNING:

page.setMessage(message, IMessageProvider.WARNING);

page.setErrorMessage(null);

break;

case IStatus.INFO:

page.setMessage(message, IMessageProvider.INFORMATION);

page.setErrorMessage(null);

break;

default:

if (message.length() == 0) {

message = null;

}

page.setMessage(null);

page.setErrorMessage(message);

break;

}

}
