Examples of LockFile

com.sun.messaging.jmq.jmsserver.util.LockFile
This class encapsulates a broker lock file. The lock file makes sure that no two brokers using the same instance name are running at the same time (using different port numbers). The algorithm goes like this: Try to create a lock file in $JMQ_VARHOME/instances/lock If lock didn't exist previously and was created then we got the lock write :hostname:port\n to lock file and return. Else if lock file already exists read it. If contents of lock file match the instancename, hostname and port of this broker then the lock file was left over from a previous run of this broker and we assume we got the lock and return. Else try to connect to the broker on host:port to see if it is still up. If we connect to broker then we failed to get lock. return. Else assume the lock file is cruft. Remove it and try to acquire again.

org.eclipse.jgit.internal.storage.file.LockFile
Git style file locking and replacement.
To modify a ref file Git tries to use an atomic update approach: we write the new data into a brand new file, then rename it in place over the old name. This way we can just delete the temporary file if anything goes wrong, and nothing has been damaged. To coordinate access from multiple processes at once Git tries to atomically create the new temporary file under a well-known name.

A simple class to support file based stores. Simulates a write lock by creating/removing a physical file on the file system @author Christian
org.sonatype.nexus.bootstrap.LockFile
File locker implementation, inspired by Eclipse Locker. It uses Java NIO {@link FileChannel#tryLock(long,long,boolean)} method to perform locking. As a commodity function, it also writes to a file a payload, making problemdiagnosing a bit easier, as reading (ie. from console) of the lock file content might reveal useful information about lock owner. All the limitations mentioned for {@link FileLock} stands. @since 2.7.0
