refresh

public void refresh()

Description copied from interface: IRefreshee

refreshes the listeners of this particular object.

Specified by:

refresh in interface IRefreshee

setRefreshInterval

public void setRefreshInterval(int milliSeconds)

setRefreshInterval sets the refresh interval for the EntityList. This interval decides how often an entity is polled to see if its value has changed. The default value is 1000, that is, the entity is polled once a second.

Parameters:

milliSeconds - an int value

getRefreshInterval

public int getRefreshInterval()

getRefreshInterval gets the refresh-interval for the entity list. The default value is 1000 milliseconds.

Returns:

an int value which is the refresh-interval

stopRefresher

public void stopRefresher()

startRefresher

public void startRefresher()

startRefresher starts the default refresher thread for the entity list,which sleeps for refreshInterval seconds.
