Method Detail

initialize

PersistenceStorer<M> initialize()

Ensures the storer instance is initialized, i.e. ready to perform storing. This method is idempotent. For a forced (re)initialization, see Storer.reinitialize().

Specified by:

initialize in interface Storer

Returns:

this.

initialize

PersistenceStorer<M> initialize(long initialCapacity)

Ensures the storer instance is initialized, i.e. ready to perform storing. If the storer instance needs to be initialized as a consequence of this call, the passed initialCapacityis considered as an estimate for the number of unique instances to be handled until the next commit. This method is idempotent, meaning if this instance is already initialized, the passed value might not have any effect. For a forced (re)initialization, see Storer.reinitialize(long).

Specified by:

initialize in interface Storer

Returns:

this.

reinitialize

PersistenceStorer<M> reinitialize()

Enforces the instance to be initialized, discarding any previous state (clearing it) if necessary prior to calling Storer.initialize().

Specified by:

reinitialize in interface Storer

Returns:

this.

reinitialize

PersistenceStorer<M> reinitialize(long initialCapacity)

Enforces the instance to be initialized, discarding any previous state (clearing it) if necessary prior to calling Storer.initialize().

Specified by:

reinitialize in interface Storer

Returns:

this.

ensureCapacity

PersistenceStorer<M> ensureCapacity(long desiredCapacity)

Ensures that the instance's internal state is prepared for handling an amount of unique instance equal to the passed value. Note that is explicitly does not have to mean that the instance's internal state actually reserves as much space, only makes a best effort to prepare for that amount. Example: an internal hash table's hash length might still remain at 2^30, despite the passed value being much higher.

Specified by:

ensureCapacity in interface Storer

Parameters:

desiredCapacity - the amount of unique instances that this instance shall prepare to handle.

Returns:

this
