Class AdaptSizeTraceReader

java.lang.Object

com.github.benmanes.caffeine.cache.simulator.parser.AbstractTraceReader

com.github.benmanes.caffeine.cache.simulator.parser.TextTraceReader

com.github.benmanes.caffeine.cache.simulator.parser.adapt_size.AdaptSizeTraceReader

All Implemented Interfaces:

TraceReader

public final class AdaptSizeTraceReader
extends TextTraceReader

A reader for the trace files provided by the authors of the AdaptSize algorithm. See traces.

The AdaptSize simulator treats identical keys with different weights as unique entries, rather than as an update to that entry's size. This behavior is emulated by a key hash.

The event features that this trace supports.

events

public Stream<AccessEvent> events()

Description copied from interface: TraceReader

Creates a stream that lazily reads the trace source.

If timely disposal of underlying resources is required, the try-with-resources construct should be used to ensure that the stream's close method is invoked after the stream operations are completed.

Returns:

a lazy stream of cache events
