All Implemented Interfaces:

Iterable<D>, Collection<D>, Set<D>

public class RtArraySet2<D>
extends AbstractSet<D>

A set implementation for real-time application. Based on an array of references. "Lock-Free" variant of a "Real-Time Array Set".
DISCUSS: not yet clear whether the old dynamic form for "size()" is more efficient, -- it needs one "atomic" variable less. (!?)
ATTENTION: This class restricts the contract of "Iterator": Once "hasNext()==false" has returned, all following behaviour is unspecified and further usage forbidden. (The Iterator object will be recycled.)

hashCode in interface Set<D>

Overrides:

hashCode in class AbstractSet<D>

add

public boolean add(D obj)

Specified by:

add in interface Collection<D>

Specified by:

add in interface Set<D>

Overrides:

add in class AbstractCollection<D>

capacity

public int capacity()

size

public int size()

ATTENTION however implemented, there is always a race condition between the result of "size()" and the following number of contained elements, unless ADDITIONALLY enclosed in some "critical section", or sim.

Specified by:

size in interface Collection<D>

Specified by:

size in interface Set<D>

Specified by:

size in class AbstractCollection<D>

clear

public void clear()

Specified by:

clear in interface Collection<D>

Specified by:

clear in interface Set<D>

Overrides:

clear in class AbstractCollection<D>

iterator

public Iterator<D> iterator()

Specified by:

iterator in interface Collection<D>

iterator in class AbstractCollection<D>

remove

public boolean remove(Object obj)

Specified by:

remove in interface Collection<D>

Specified by:

remove in interface Set<D>

Overrides:

remove in class AbstractCollection<D>

any

@Opt
public D any()

Get one arbitrarily chosen element and remove it.
(This is an dditional method not in the "java.util.Set" interface.)

forEach

public void forEach(Consumer<? super D> acc)

Apply code to all elements.
