Public Function Get ( _ key As CacheableKey, _ callback As IGFSerializable _ ) As IGFSerializable
public: IGFSerializable^ Get ( CacheableKey^ key, IGFSerializable^ callback )
key whose associated value is to be returned -- the key object must implement the Equals and GetHashCode methods.
An argument passed into the CacheLoader if loader is used. Has to be Serializable (i.e. implement IGFSerializable); can be null.
Return Valuevalue, or null if the value is not found and can't be loaded
If the value is not present locally then it is requested from the java server. If even that is unsuccessful then a local CacheLoader will be invoked if there is one.
The value returned by get is not copied, so multi-threaded applications should not modify the value directly, but should use the update methods.
Updates the LastModifiedTime (if a new value is loaded) for this region and the entry., , and
