public class HazelcastExpiryPolicy extends Object implements javax.cache.expiry.ExpiryPolicy, IdentifiedDataSerializable, Serializable
Hazelcast provides overloads of the typical cache operations with a custom
ExpiryPolicy
parameter.
This class provides a custom implementation of an ExpiryPolicy
to
react on all three types of policies:
Sample usage:
ICache<Key, Value> unwrappedCache = cache.unwrap( ICache.class ); HazelcastExpiryPolicy customExpiry = new HazelcastExpiryPolicy(20, 30, 40, TimeUnit.SECONDS); unwrappedCache.put("key1", value, customExpiry );
Constructor and Description |
---|
HazelcastExpiryPolicy()
Default constructor to serialize/deserialize
|
HazelcastExpiryPolicy(javax.cache.expiry.Duration create,
javax.cache.expiry.Duration access,
javax.cache.expiry.Duration update)
Constructs an expiry policy with provided values for creation, access and update by providing
instances of the
Duration class. |
HazelcastExpiryPolicy(javax.cache.expiry.ExpiryPolicy expiryPolicy)
Copy Constructor for an already existing
ExpiryPolicy . |
HazelcastExpiryPolicy(long createMillis,
long accessMillis,
long updateMillis)
Constructs an expiry policy with provided values for creation, access and update in milliseconds.
|
HazelcastExpiryPolicy(long createDurationAmount,
long accessDurationAmount,
long updateDurationAmount,
TimeUnit timeUnit)
Constructs an expiry policy with provided values for creation, access and update as well as a
TimeUnit to convert those values to internally used time unites. |
