    • Method Detail

      • canExpire

        public final boolean canExpire()
        Returns:
        true if the entry can expire, false otherwise
      • canExpireMaxIdle

        public boolean canExpireMaxIdle()
        Returns:
        true if this entry can expire via max idle, false otherwise
      • setMaxIdle

        public void setMaxIdle​(long maxIdle)
      • getCreated

        public long getCreated()
        Returns:
        timestamp when the entry was created
      • getLastUsed

        public final long getLastUsed()
        Returns:
        timestamp when the entry was last used
      • getLifespan

        public long getLifespan()
        Returns:
        retrieves the lifespan of this entry. -1 means an unlimited lifespan.
      • getExpiryTime

        public long getExpiryTime()
        Description copied from interface: InternalCacheEntry
        Only used with entries that have a lifespan, this determines when an entry is due to expire.
        Returns:
        timestamp when the entry is due to expire, or -1 if it doesn't have a lifespan
      • getMaxIdle

        public final long getMaxIdle()
        Returns:
        the maximum allowed time for which this entry can be idle, after which it is considered expired.
      • toInternalCacheValue

        public InternalCacheValue<?> toInternalCacheValue()
        Description copied from interface: InternalCacheEntry
        Creates a representation of this entry as an InternalCacheValue. The main purpose of this is to provide a representation that does not have a reference to the key. This is useful in situations where the key is already known or stored elsewhere, making serialization and deserialization more efficient.

        Note that this should not be used to optimize memory overhead, since the saving of an additional reference to a key (a single object reference) does not warrant the cost of constructing an InternalCacheValue. This only makes sense when marshalling is involved, since the cost of marshalling the key again can be sidestepped using an InternalCacheValue if the key is already known/marshalled.

        Returns:
        a new InternalCacheValue encapsulating this InternalCacheEntry's value and expiration information.
