Method Detail

addChangeListener

public void addChangeListener(ChangeListener<E> changeListener)

Description copied from interface: ChangeGenerator

Allow Notify all ChangeListeners about a change

Specified by:

addChangeListener in interface ChangeGenerator<E extends TokenEvent<T>>

getListeners

public List<ChangeListener<E>> getListeners()

Description copied from interface: ChangeGenerator

Get list directly. Support DI; like Spring IOC

Specified by:

getListeners in interface ChangeGenerator<E extends TokenEvent<T>>

Returns:

the listeners

setListeners

public void setListeners(List<ChangeListener<E>> listeners)

Description copied from interface: ChangeGenerator

Set list directly. Support DI; like Spring IOC

Specified by:

setListeners in interface ChangeGenerator<E extends TokenEvent<T>>

Parameters:

listeners - the listeners to set

notifyAllListeners

public void notifyAllListeners(E event)

Notify all listeners with updates to TokenEvent.

If TokenEvent is of type SupplierTokenEvent and was not Consumable.wasConsumed() then Some actions maybe in Supplier SupplierTokenEvent.getTokens(), so execute them nevertheless by default incase there.

Specified by:

notifyAllListeners in interface ChangeGenerator<E extends TokenEvent<T>>
