createReference

public ConcurrentReferenceHashMap.Reference<K,V> createReference(ConcurrentReferenceHashMap.Entry<K,V> entry,
                                                                 int hash,
                                                                 ConcurrentReferenceHashMap.Reference<K,V> next)

Factory method used to create a new ConcurrentReferenceHashMap.Reference.

参数:

entry - the entry contained in the reference

hash - the hash

next - the next reference in the chain or null

返回:

a new ConcurrentReferenceHashMap.Reference

pollForPurge

public ConcurrentReferenceHashMap.Reference<K,V> pollForPurge()

Return any reference that has been garbage collected and can be purged from the underlying structure or null if no references need purging. This method must be thread safe and ideally should not block when returning null. References should be returned once and only once.

返回:

a reference to purge or null
