Method Summary

Method Detail

refreshedURLCache

void refreshedURLCache(URLCache uc,
                       boolean refreshSuccessful,
                       java.io.IOException reasonForFailure)

This method is called when a call to URLCache.refresh() completes. This method is to return quickly as a hold-up here delays the completion of a call to URLCache.refresh()! The object monitor of the given URLCache instance is held while this method executes, which blocks further refresh() calls; it does not block access to previously cached data, however.

Parameters:

uc - The URLCache object that performed the refresh

refreshSuccessful - indicating whether the cache was successfully updated;

reasonForFailure - contains the exception that caused the refresh to fail; is null if update was successful
