| Element | | final public class Element implements Serializable,Cloneable(Code) | | A Cache Element, consisting of a key, value and attributes.
From ehcache-1.2, Elements can have keys and values that are Serializable or Objects. To preserve backward
compatibility, special accessor methods for Object keys and values are provided:
Element.getObjectKey() and
Element.getObjectValue() . If placing Objects in ehcache, developers must use the new getObject... methods to
avoid CacheExceptions. The get... methods are reserved for Serializable keys and values.

| Method Summary | |
| final public Object | clone()
Clones an Element. | | final public boolean | equals(Object object)
Equals comparison with another element, based on the key. | | final public long | getCreationTime()
Gets the creationTime attribute of the ElementAttributes object. | | public long | getExpirationTime()
Returns the expiration time based on time to live. | | final public long | getHitCount()
Gets the hit count on this element. | | final public Serializable | getKey()
Gets the key attribute of the Element object.
The key value. | | final public long | getLastAccessTime()
Gets the last access time.
Access means a get. | | public long | getLastUpdateTime()
If there is an Element in the Cache and it is replaced with a new Element for the same key,
then both the version number and lastUpdateTime should be updated to reflect that. | | final public long | getNextToLastAccessTime()
Gets the next to last access time. | | final public Object | getObjectKey()
Gets the key attribute of the Element object.
This method is provided for those wishing to use ehcache as a memory only cache
and enables retrieval of non-Serializable values from elements.
The key as an Object. | | final public Object | getObjectValue()
Gets the value attribute of the Element object as an Object.
This method is provided for those wishing to use ehcache as a memory only cache
and enables retrieval of non-Serializable values from elements.
The value as an Object. | | final public long | getSerializedSize()
The size of this object in serialized form. | | public int | getTimeToIdle()
| | public int | getTimeToLive()
| | final public Serializable | getValue()
Gets the value attribute of the Element object.
The value which must be Serializable. | | final public long | getVersion()
Gets the version attribute of the ElementAttributes object. | | final public int | |
