              Set<Class<? extends SciJavaEvent>> highlighted)

Gets the recorded event history as an HTML string.

Parameters:

filtered - Set of event types to filter out from the history.

highlighted - Set of event types to highlight in the history.

Returns:

An HTML string representing the recorded event history.

addListener

void addListener(EventHistoryListener l)

Adds an event history listener. This mechanism exists (rather than using the event bus) to avoid event feedback loops when reporting history changes.

removeListener

void removeListener(EventHistoryListener l)

Removes an event history listener. This mechanism exists (rather than using the event bus) to avoid event feedback loops when reporting history changes.
