Method Detail

getInstanceOf

public static DefaultUniqueIdGenerator getInstanceOf()

Return the singleton of the DefaultUniqueIdGenerator. Should be use in place of the constructor of the present class.

Returns:

- The singleton of the unique id generator.

getCurrentPropertyId

public int getCurrentPropertyId()

Return the current maximum Id of Properties

Returns:

getCurrentCharacteristicId

public int getCurrentCharacteristicId()

Return the current maximum Id of Characteristics

Returns:

incrementAndGetPropertyId

public int incrementAndGetPropertyId()

Get a new id, incremented on one and add it in the list.

Returns:

- a new and incremented of one single id.

incrementAndGetCharacteristicId

public int incrementAndGetCharacteristicId()

Get a new id, incremented on one and add it in the list.

Returns:

- a new and incremented of one single id.

incrementAndGetPropertyId

public int incrementAndGetPropertyId(int increment)

Get a new id, incremented on one and add it in the list.

Parameters:

increment - - increment for the new id w.r.p the current Id.

Returns:

- a new and incremented of the given increment single id.

incrementAndGetCharacteristicId

public int incrementAndGetCharacteristicId(int increment)

Get a new id, incremented on one and add it in the list.

Parameters:

increment - - increment for the new id w.r.p the current Id.

Returns:

- a new and incremented of the given increment single id.

tryToAddPropertyId

public boolean tryToAddPropertyId(int id)

If the id list does not contains the given Id, the present method tries to add it into the id list or return false otherwise. If the given id is higher than the current id this last one is set equal to the given id.

Parameters:

id - - Given input id.

Returns:

true if the id has been successfully added to the id list, false otherwise.

tryToAddCharacteristicId

public boolean tryToAddCharacteristicId(int id)
