Method Detail

getValues

public V[] getValues()

getExpirationTime

public long getExpirationTime()

Description copied from interface: Expirable

Gets the expiration time for this object

Specified by:

getExpirationTime in interface Expirable

Returns:

an expiration time, in milliseconds since the Unix epoch. The special value 0 indicates that the object is valid indefinitely.

expire

public void expire()

Description copied from interface: Expirable

An operation to be executed when an item expires. Turns the object into a "tombstone" which occupies minimal memory in the expiration heap. This is an alternative to removing an object from the heap, which is expensive; the tombstone exists until it expires, but must not be used.

Specified by:

expire in interface Expirable

isExpired

public boolean isExpired()

Description copied from interface: Expirable

Tests the object for "tombstone" status

Specified by:

isExpired in interface Expirable

Returns:

whether this object is a tombstone which must not be used

compareByExpirationTime

public int compareByExpirationTime(Solution<V> other)

hashCode

public int hashCode()

Overrides:

hashCode in class Object

equals

public boolean equals(Object other)

Overrides:

equals in class Object
