Henriksen (Java Libraries for Stochastic Simulation)

java.lang.Object
- umontreal.iro.lecuyer.simevents.eventlist.Henriksen

All Implemented Interfaces:

java.lang.Iterable<Event>, EventList
```
public class Henriksen
extends java.lang.Object
implements EventList
```
An implementation of EventList using the doubly-linked indexed list of Henriksen (see also).
Events are stored in a normal doubly-linked list. An additionnal index array is added to the structure to allow quick access to the events.

Method Summary

Methods
Modifier and Type	Method and Description
`void`	`add(Event ev)` Adds a new event in the event list, according to the time of `ev`.
`void`	`addAfter(Event ev, Event other)` Same as `add`, but adds the new event `ev` immediately after the event `other` in the list.
`void`	`addBefore(Event ev, Event other)` Same as `add`, but adds the new event `ev` immediately before the event `other` in the list.
`void`	`addFirst(Event ev)` Adds a new event at the beginning of the event list.
`void`	`clear()` Empties the event list, i.e., cancels all events.
`Event`	`getFirst()` Returns the first event in the event list.
`<E extends Event> E`	`getFirstOfClass(java.lang.Class<E> cl)` Returns the first event of the class `E` (a subclass of `Event`) in the event list.
`Event`	`getFirstOfClass(java.lang.String cl)` Returns the first event of the class `cl` (a subclass of `Event`) in the event list.
`boolean`	`isEmpty()` Returns `true` if and only if the event list is empty (no event is scheduled).
`java.util.Iterator<Event>`	`iterator()`
`java.util.ListIterator<Event>`	`listIterator()` Returns a list iterator over the elements of the class `Event` in this list.
`boolean`	`remove(Event ev)` Removes the event `ev` from the event list (cancels this event).
`Event`	`removeFirst()` Removes the first event from the event list (to cancel or execute this event).
`java.lang.String`	`toString()`

  - isEmpty
```
public boolean isEmpty()
```
    Description copied from interface: EventList
    
    Returns true if and only if the event list is empty (no event is scheduled).
    
    Specified by:
    
    isEmpty in interface EventList
    
    Returns:
    true if the event list is empty
  - clear
```
public void clear()
```
    Description copied from interface: EventList
    
    Empties the event list, i.e., cancels all events.
    
    Specified by:
    
    clear in interface EventList
  - add
```
public void add(Event ev)
```
    Description copied from interface: EventList
    
    Adds a new event in the event list, according to the time of ev. If the event list contains events scheduled to happen at the same time as ev, ev must be added after all these events.
    
    Specified by:
    
    add in interface EventList
    
    Parameters:
    ev - event to be added
  - addFirst
```
public void addFirst(Event ev)
```
    Description copied from interface: EventList
    
    Adds a new event at the beginning of the event list. The given event ev will occur at the current simulation time.
    
    Specified by:
    
    addFirst in interface EventList
    
    Parameters:
    ev - event to be added
  - addBefore
```
public void addBefore(Event ev,
             Event other)
```
    Description copied from interface: EventList
    
    Same as add, but adds the new event ev immediately before the event other in the list.
    
    Specified by:
    
    addBefore in interface EventList
    
    Parameters:
    ev - event to be added
    other - reference event before which ev will be added
  - addAfter
```
public void addAfter(Event ev,
            Event other)
```
    Description copied from interface: EventList
    
    Same as add, but adds the new event ev immediately after the event other in the list.
    
    Specified by:
    
    addAfter in interface EventList
    
    Parameters:

    other - reference event after which ev will be added
  - getFirst
```
public Event getFirst()
```
    Description copied from interface: EventList
    
    Returns the first event in the event list. If the event list is empty, returns null.
    
    Specified by:
    
    getFirst in interface EventList
    
    Returns:
    the first event in the event list, or null if the list is empty
  - getFirstOfClass
```
public Event getFirstOfClass(java.lang.String cl)
```
    Description copied from interface: EventList
    
    Returns the first event of the class cl (a subclass of Event) in the event list. If no such event is found, returns null.
    
    Specified by:
    
    getFirstOfClass in interface EventList
    
    Returns:
    the first event of class cl, or null if no such event exists in the list
  - getFirstOfClass
```
public <E extends Event> E getFirstOfClass(java.lang.Class<E> cl)
```
    Description copied from interface: EventList
    
    Returns the first event of the class E (a subclass of Event) in the event list. If no such event is found, returns null.
    
    Specified by:
    
    getFirstOfClass in interface EventList
    
    Returns:
    the first event of class cl, or null if no such event exists in the list
  - iterator
```
public java.util.Iterator<Event> iterator()
```
    Specified by:
    
    iterator in interface java.lang.Iterable<Event>
  - listIterator
```
public java.util.ListIterator<Event> listIterator()
```
    Description copied from interface: EventList
    
    Returns a list iterator over the elements of the class Event in this list.
    
    Specified by:
    
    listIterator in interface EventList
    
    Returns:
    a list iterator over the elements of the class Event in this list
  - remove
```
public boolean remove(Event ev)
```
    Description copied from interface: EventList
    
    Removes the event ev from the event list (cancels this event). Returns true if and only if the event removal has succeeded.
    
    Specified by:
    
    remove in interface EventList
    
    Parameters:
    ev - event to be removed
    
    Returns:
    true if the event was successfully removed from the list
  - removeFirst
```
public Event removeFirst()
```
    Description copied from interface: EventList
    
    Removes the first event from the event list (to cancel or execute this event). Returns the removed event. If the list is empty, then null is returned.
    
    Specified by:
    
    removeFirst in interface EventList
