Method Detail

getEventlineObjectsIterator

public java.util.Iterator<T> getEventlineObjectsIterator(ITimeSpan span)

Description copied from interface: IEventlineModel

Returns an iterator for those eventline objects that are placed on the eventline during the given span.

Specified by:

getEventlineObjectsIterator in interface IEventlineModel<T extends IEventlineObject>

Parameters:

span - the time span for which to return the timeline objects

Returns:

an iterator for timeline objects on the eventline (for the given time span)

getTimeSpan

public ITimeSpan getTimeSpan(T eventlineObject)

Description copied from interface: IEventlineModel

Returns the time span allocated to the given object.

Specified by:

getTimeSpan in interface IEventlineModel<T extends IEventlineObject>

Parameters:

eventlineObject - the timeline object

Returns:

a time span for the given object

setTimeSpan

public void setTimeSpan(T eventlineObject,
                        ITimeSpan span)

Sets a new time span on the given eventline object.

Parameters:

eventlineObject - the eventline object that will get a new time span allocation

span - the new time span
