Interface Pretoucher

All Superinterfaces:

AutoCloseable, Closeable

public interface Pretoucher
extends Closeable

A class designed to be called from a long-lived thread. To get an instance of a Pretoucher, call PretouchUtil.createPretoucher(SingleChronicleQueue)

Upon invocation of the execute() method, this object will pre-touch pages in the supplied queue's underlying store file, attempting to keep ahead of any appenders to the queue.

Resources held by this object will be released when the underlying queue is closed.

Alternatively, the close() method can be called to close the supplied queue and release any other resources. Invocation of the execute() method after close() has been called will cause an InvalidEventHandlerException to be thrown.
