setValue

void setValue(V value)

Sets the value of this NearCacheRecord.

Parameters:

value - the value for this NearCacheRecord

setCreationTime

void setCreationTime(long time)

Sets the creation time of this Evictable in milliseconds.

Parameters:

time - the creation time for this Evictable in milliseconds

setAccessTime

void setAccessTime(long time)

Sets the access time of this Evictable in milliseconds.

Parameters:

time - the latest access time of this Evictable in milliseconds

setAccessHit

Sets the access hit count of this Evictable.

Parameters:

hit - the access hit count for this Evictable

incrementAccessHit

void incrementAccessHit()

Increases the access hit count of this Evictable by 1.

resetAccessHit

void resetAccessHit()

Resets the access hit count of this Evictable to 0.

isIdleAt

boolean isIdleAt(long maxIdleMilliSeconds,
                 long now)

Checks whether the maximum idle time is passed with respect to the provided time without any access during this time period as maxIdleSeconds.

Parameters:

maxIdleMilliSeconds - maximum idle time in milliseconds

now - current time in milliseconds
