Constructor Detail

HubAutoSequence

public HubAutoSequence()

HubAutoSequence

public HubAutoSequence(Hub hub,
                       String propertyName,
                       int startNumber)

Create a new HubAutoSequence.

Parameters:

propertyName - is int property for storing number.

HubAutoSequence

public HubAutoSequence(Hub hub,
                       String propertyName,
                       int startNumber,
                       boolean bKeepSeq)

Create a new HubAutoSequence.

Parameters:

propertyName - is int property for storing number.

bKeepSeq, - if false then seq numbers are not updated when an object is removed

HubAutoSequence

public HubAutoSequence(Hub hub,
                       String propertyName,
                       int startNumber,
                       boolean bKeepSeq,
                       boolean bServerSideOnly)

Parameters:

hub -

propertyName -

startNumber -

bKeepSeq -

bServerSideOnly - this is used by Hub.setAutoSequence(...) so that the server will control the seq property and send CS messages to clients. If true, then the property changes (for seq prop) will need to be sent to clients.

HubAutoSequence

public HubAutoSequence(Hub hub,
                       String propertyName)

Create a new HubAutoSequence.

Parameters:

propertyName - is int property for storing number.
