CopiedOnHeapValueHolder

protected CopiedOnHeapValueHolder(long id,
                                  V value,
                                  long creationTime,
                                  long expirationTime,
                                  Copier<V> valueCopier)

CopiedOnHeapValueHolder

public CopiedOnHeapValueHolder(Store.ValueHolder<V> valueHolder,
                               V value,
                               Copier<V> valueCopier,
                               long now,
                               Duration expiration)

Constructor to build this value holder from another value holder. As such we assume that the passed in value is internal and so has been copied for write already elsewhere.

Parameters:

valueHolder - reference value holder

value - the value

valueCopier - the copier to use for copyForRead

now - timestamp in millis

expiration - computed expiration duration

CopiedOnHeapValueHolder

public CopiedOnHeapValueHolder(V value,
                               long creationTime,
                               Copier<V> valueCopier)

CopiedOnHeapValueHolder

public CopiedOnHeapValueHolder(V value,
                               long creationTime,
                               long expirationTime,
                               Copier<V> valueCopier)
