public interface IElementAttributes
Interface for cache element attributes classes. Every item is the cache is associated with an element attributes object. It is used to track the life of the object as well as to restrict its behavior. By default, elements get a clone of the region's attributes.

Method Detail |
---|
void setMaxLifeSeconds(long mls)
mls
- The new MaxLifeSeconds valuelong getMaxLifeSeconds()
If this is exceeded the element will not be returned, instead it will be removed. It will be removed on retrieval, or removed actively if the memory shrinker is turned on.
void setIdleTime(long idle)
If this is exceeded the element will not be returned, instead it will be removed. It will be removed on retrieval, or removed actively if the memory shrinker is turned on.
idle
- The new idleTime valuevoid setSize(int size)
size
- The new size valueint getSize()
long getCreateTime()
This should be the current time in milliseconds returned by the sysutem call when the element is put in the cache.
Putting an item in the cache overrides any existing items.
long getLastAccessTime()
void setLastAccessTimeNow()
long getIdleTime()
long getTimeToLiveSeconds()
This is the (max life + create time) - current time.

boolean getIsSpool()
By default this is true.
void setIsSpool(boolean val)
By default this is true.
val
- The new isSpool valueboolean getIsLateral()
By default this is true.
void setIsLateral(boolean val)
By default this is true.
val
- The new isLateral valueboolean getIsRemote()
By default this is true.
void setIsRemote(boolean val)
By default this is true.

- The new isRemote valueboolean getIsEternal()
void setIsEternal(boolean val)
val
- The new isEternal valuevoid addElementEventHandler(IElementEventHandler eventHandler)
eventHandler
- The feature to be added to the ElementEventHandlerArrayList getElementEventHandlers()
Event handlers are transient. The only events defined are in memory events. All handlers are lost if the item goes to disk.
