com.tangosol.net.cache.CompactSerializationCache.InternalEvictionPolicy
protected abstract class CompactSerializationCache.InternalEvictionPolicy
InternalEvictionPolicy is an abstract base implementation of an CompactSerializationCache.InternalEvictionPolicy
used by this CompactSerializationCache.
Nested Class Summary | |
---|---|
protected class |
CompactSerializationCache.InternalEvictionPolicy.EvictionCandidate EvictionCandidate represents a candidate for eviction during the calculation of the eviction set, representing the key, its relative "weight" as assigned by the configured CompactSerializationCache.InternalEvictionPolicy as well as its size in units. |
protected class |
CompactSerializationCache.InternalEvictionPolicy.EvictionVisitor SafeEntryVisitor implementation that calculates the set of eviction candidates. |
Field Summary | |
---|---|
protected BinaryLongMap.EntryVisitor |
f_visitorTouchCount The singleton stateless visitor to update the touch-count map. |
protected BinaryLongMap.EntryVisitor |
f_visitorTouchTime The singleton stateless visitor to update the touch-time map. |
protected long |
m_ldtLastEvict The date-time of the last eviction. |

protected abstract long |
calculateWeight(Binary binKey) Calculate the "weight" of the entry associated with the specified key. |
void |
entryTouched(Binary binKey) This method is called by the cache to indicate that the entry for the specified key has been touched. |

entryTouched(ConfigurableCacheMap.Entry entry) This method is called by the cache to indicate that an entry has been touched. |
protected abstract ConfigurableCacheMap.EvictionPolicy |
getConfiguredPolicy() Return the configured EvictionPolicy instance. |
java.lang.String |
getName() Obtain the name of the eviction policy. |
void |
requestEviction(int cMaximum) This method is called by the cache when the cache requires the eviction policy to evict entries. |
protected void |
touchInternal(Binary binKey) Update the internally maintained "touch"-related statistics for the specified key (e.g. touch time and touch count). |
