Constructor Detail

WithInlineEviction

public WithInlineEviction(ElementMatcher<? super S> matcher,
                          ConcurrentMap<? super S,Boolean> map,
                          int evictionSize)

Creates a new caching matcher with inlined cache eviction.

Parameters:

matcher - The underlying matcher to apply for non-cached targets.

map - A map that serves as a cache for previous matches. This match is strongly referenced and can cause a memory leak if it is not evicted while keeping this matcher alive.

evictionSize - The maximum amount of entries in this map before removing a random entry from the map.

Method Detail

onCacheMiss

protected boolean onCacheMiss(@MaybeNull
                              S target)

Invoked if the cache is not hit.

Overrides:

onCacheMiss in class CachingMatcher<S>

Parameters:

target - The element to be matched.

Returns:

true if the element is matched.
