Constructor Details

Entry

public Entry(Object oKey,
 Object oValue)

Construct an Entry.

Parameters:

oKey - the Entry key

oValue - the Entry value (optional)

Method Details

getValue

public Object getValue()

Returns the value corresponding to this entry.

Specified by:

getValue in interface InvocableMap.Entry

Specified by:

getValue in interface Map.Entry

Overrides:

getValue in class AbstractKeyBasedMap.EntrySet.Entry

Returns:

the value corresponding to this entry

touch

public void touch()

Indicate to the entry that it has been touched, such as when it is accessed or modified.

Specified by:

touch in interface ConfigurableCacheMap.Entry

getTouchCount

public int getTouchCount()

Determine the number of times that the cache entry has been touched (since the touch count was last reset).

Specified by:

getTouchCount in interface ConfigurableCacheMap.Entry

Returns:

the number of times that the cache entry has been touched

getLastTouchMillis

public long getLastTouchMillis()

Determine when the cache entry was last touched.

Specified by:

getLastTouchMillis in interface ConfigurableCacheMap.Entry

Returns:

the date/time value, in millis, when the entry was most recently touched

getExpiryMillis

public long getExpiryMillis()

Determine when the cache entry will expire, if ever.

Specified by:

getExpiryMillis in interface ConfigurableCacheMap.Entry

Returns:

the date/time value, in millis, when the entry will (or did) expire; zero indicates no expiry

setExpiryMillis

public void setExpiryMillis(long lMillis)

Specify when the cache entry will expire, or disable expiry. Note that if the cache is configured for automatic expiry, each subsequent update to this cache entry will reschedule the expiry time.

Specified by:

setExpiryMillis in interface ConfigurableCacheMap.Entry

Parameters:

lMillis - pass the date/time value, in millis, for when the entry will expire, or pass zero to disable automatic expiry

getUnits

public int getUnits()

Determine the number of cache units used by this Entry.

Specified by:

getUnits in interface ConfigurableCacheMap.Entry

Returns:

an integer value 0 or greater, with a larger value signifying a higher cost; -1 implies that the Entry has been discarded

setUnits

public void setUnits(int cUnits)

Specify the number of cache units used by this Entry.

Specified by:

setUnits in interface ConfigurableCacheMap.Entry

Parameters:

cUnits - an integer value 0 or greater, with a larger value signifying a higher cost

setCacheEntry

protected void setCacheEntry(ConfigurableCacheMap.Entry entryBacking)

Configure the backing map cache entry.

Parameters:

entryBacking - the entry to delegate most of this entry's operations to

getCacheEntry

protected ConfigurableCacheMap.Entry getCacheEntry()

Obtain the actual cache entry from the partition-specific backing map.

Returns:

the actual underlying cache entry
