Method Summary

Modifier and Type	Method	Description
NamedLock	getLock(String name)	Creates or reuses existing NamedLock.

Method Details

getLock

NamedLock getLock(String name)

Creates or reuses existing NamedLock. Returns instance MUST BE treated as "resource", best in try-with-resource block.

Parameters:

name - the lock name, must not be null.

Returns:

named lock instance, never null.

shutdown

void shutdown()

Performs a clean shut down of the factory.

onFailure

default <E extends Throwable> E onFailure(E failure)

Method to notify factory about locking failure, to make it possible to provide more (factory specific) information about factory state when a locking operation failed. Factory may alter provided failure or provide information via some other side effect (for example via logging).
