toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object

add

public final void add(E e)

Returns the number of events presently stored.

Returns:

the number of events

capacity

public int capacity()

Returns the capacity

Returns:

the capacity

iterator

public final java.util.Iterator<E> iterator()

Returns the iterator over events. This iterator starts with the most recently added event and ends with the first event added or with the capacity event if more have been added than the buffer's capacity.

Specified by:

iterator in interface java.lang.Iterable<E extends BasicEvent>

Returns:

an iterator that can iterate over past events. Starts with most recently added event.
