Examples of org.prevayler.PrevaylerFactory

org.prevayler.PrevaylerFactory
Provides easy access to all Prevayler configurations and implementations available in this distribution. Static methods are also provided as short-cuts for the most common configurations.

By default, the Prevayler instances created by this class will write their Transactions to .journal files before executing them. The FileDescriptor.sync() method is called to make sure the Java file write-buffers have been written to the operating system. Many operating systems, including most recent versions of Linux and Windows, allow the hard-drive's write-cache to be disabled. This guarantees no executed Transaction will be lost in the event of a power shortage, for example.

Also by default, the Prevayler instances created by this class will execute deep copies of transactions, not the transactions themselves, so that unrecoverable changes to the prevalent system and unrecoverable uses of reference equality inside transactions fail fast as they would upon recovery. @param < P> The type of object you intend to persist as a Prevalent System.
