one.microstream.collections.ListAccessor<E>

All Implemented Interfaces:

Iterable<E>, CapacityCarrying, ExtendedBag<E>, ExtendedCollection<E>, ExtendedList<E>, ExtendedSequence<E>, ReleasingCollection<E>, Sized, Sortable<E>, XGettingBag<E>, XGettingCollection<E>, XGettingList<E>, XGettingSequence<E>, XIndexIterable<E>, XIterable<E>, XJoinable<E>, XOrderingSequence<E>, XReplacingBag<E>, XReplacingCollection<E>, XSettingList<E>, XSettingSequence<E>, XSortableSequence<E>, Copyable

public class ListAccessor<E>
extends Object
implements XSettingList<E>

Wrapper class that reduces the services provided by any wrapped XSettingList to only those ofXSettingList, effectively making the wrapped XSettingList instance structural unmodifiable if used through an instance of this class.

All methods declared in XSettingList are transparently passed to the wrapped list.
All structural modifying methods declared in Collection and List(all variations of add~(), remove~() and retain~() as well as clear()) immediately throw an UnsupportedOperationException when called.

This concept can be very useful if a class wants to provide public read and write access to an internal list without either the danger of the list being structurally modified from the outside or the need to copy the whole list on every access.

This is one of many useful concepts that are missing in the JDK Collections Framework and thus so far lead to either inefficient or unneccessary verbose program code (or both).

Method Detail

equality

public final Equalator<? super E> equality()

Specified by:

equality in interface XGettingCollection<E>

hasVolatileElements

public final boolean hasVolatileElements()

Description copied from interface: XGettingCollection

Tells if this collection contains volatile elements.
An element is volatile, if it can become no longer reachable by the collection without being removed from the collection. Examples are WeakReference of SoftReference or implementations of collection entries that remove the element contained in an entry by some means outside the collection.
Note that WeakReference instances that are added to a a simple (non-volatile) implementation of a collection do NOT make the collection volatile, as the elements themselves (the reference instances) are still strongly referenced.

Specified by:

hasVolatileElements in interface ExtendedCollection<E>

Specified by:

hasVolatileElements in interface XGettingCollection<E>

Returns:

true if the collection contains volatile elements.

Returns:

whether this collection contains exactely the given element.

equals

@Deprecated
public final boolean equals(Object o)

Deprecated.

Description copied from interface: XGettingCollection

Performs an equality comparison according to the specification in Collection.

Note that it is this interface's author opinion that the whole concept of equals() in standard Java, especially in the collection implementations, is flawed.
The reason is because all different kinds of comparison types that actually depend on the situation have to be mixed up in a harcoded fashion in one method, from identity comparison over data indentity comparison to content comparison.
In order to get the right behavior in every situation, one has to distinct between different types of equality

This means several things:
1.) You can't just say for example an ArrayList is the "same" as a LinkedList just because they contain the same content.
There are different implementations for a good reason, so you have to distinct them when comparing. There are simple code examples which create massive misbehavior that will catastrophically ruin the runtime behavior of a programm due to this error in Java / JDK / Sun / whatever.
2.) You can't always determine equality of two collections by determining equality of each element as Collection defines it.

As a conclusion: don't use this method!
Be clear what type of comparison you really need, then use one of the following methods and proper comparators:
XGettingCollection.equals(XGettingCollection,Equalator)
XGettingCollection.equalsContent(XGettingCollection,Equalator)

equals in interface XGettingCollection<E>

equals

public final boolean equals(XGettingCollection<? extends E> samples,
                            Equalator<? super E> equalator)

Description copied from interface: XGettingCollection

Returns true if the passed collection is of the same type as this collection andthis.equalsContent(list, equalator) yields true.

Specified by:

equals in interface XGettingCollection<E>

equalsContent

public final boolean equalsContent(XGettingCollection<? extends E> samples,
                                   Equalator<? super E> equalator)

Description copied from interface: XGettingCollection

Returns true if all elements of this list and the passed list are sequentially equal as defined by the passed equalator.

Note that for colletion types that don't have a defined order of elements, this method is hardly usable (as is XGettingCollection.equals(Object) for them as defined in Collection). The core problem of comparing collections that have no defined order is that they aren't really reliably comparable to any other collection.

Specified by:

equalsContent in interface XGettingCollection<E>

equalator - the equalator to use to determine the equality of each element

true if this list is equal to the passed list, false otherwise
