Constructor Detail

Standard

public Standard(int capacity,
                int mergeFac)

Constructor for the Standard object. Calling this constructor merely creates an instance of the superclass.

Method Detail

setState

public void setState(Properties state)

Use the given properties for this object.

Parameters:

state - the desired properties

getState

public Properties getState(Properties p)

Return the properties of this Standard.

Parameters:

p - the properties which will be also returned for your convenience

Returns:

the properties of this Standard

add

public void add(BarrelReader reader)

Append a new barrel to the existing data structure. When the algorithm decides that it has to rebuild the actual barrel structures it calls merger.

Specified by:

add in class Dynamizer

Parameters:

reader - the data structure to append

add

public void add(BarrelReader reader,
                String srcLocation)

Description copied from class: Dynamizer

Pullovers (moves) a new barrel to the existing data structure. When the algorithm decides that it has to rebuild the actual barrel structures it must optimize.

Specified by:

add in class Dynamizer

srcLocation - location of the structure to be pulled over

optimize

public void optimize(boolean useSoftDelete)

Optimize the data structure following a delete (or remove) operation on the managed Barrels. Call this method only after first removing an element.

Specified by:

optimize in class Dynamizer

Parameters:

useSoftDelete - true meand don't delete barrels directly, only log them as dead barrels. false means direct delete

lock

public boolean lock()

Not implemented, transactions are not supported.

Returns:

true

unlock

public boolean unlock()

Not implemented, transactions are not supported.

Returns:

true
