Methods

o out 
 public final void out()
Removes this item from the list (if any) that it is currently in. If it is not currently in a list, the call has no effect.

o follow 
 public final void follow(simset.Linkage ptr)
Inserts this item after a specified item.

The item is inserted after the one referred to by the parameter, after having removed it from the list (if any) that is currently in. If the parameter refers to a Head, the effect is to put this object into first place in the list. If the parameter is null or does not belong to a list and is not a Head object, the effect is the same as out().

Parameters:
ptr - a pointer to the Linkage after which this item is to be inserted.
o precede 
 public final void precede(simset.Linkage ptr)
Inserts this item before a specified item.

The item is inserted before the one referred to by the parameter, after having removed it from the list (if any) that is currently in. If the parameter refers to a Head, the effect is to put this object into last place in the list. If the parameter is null or does not belong to a list and is not a Head object, the effect is the same as out().

Parameters:
ptr - a pointer to the Linkage after which this item is to be inserted.
o into 
 public final void into(simset.Head s)
Inserts this item as the last member of a list.

The item is inserted last in the list referred to by the parameter, after having removed it from any list that is currently in. If the parameter is null, the effect is the same as out().

Parameters:
ptr - a pointer to the list into which this item is to be inserted.
