equals
Deprecated.Description copied from interface:XGettingCollection
Performs an equality comparison according to the specification inCollection
.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 asCollection
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)
- Specified by:
equals
in interfaceXGettingCollection<E>

-
equalsContent
public boolean equalsContent(XGettingCollection<? extends E> samples, Equalator<? super E> equalator)Description copied from interface:XGettingCollection
Returnstrue
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 inCollection
). 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 interfaceXGettingCollection<E>
equalator

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

hasVolatileElements
public 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 areWeakReference
ofSoftReference
or implementations of collection entries that remove the element contained in an entry by some means outside the collection.
Note thatWeakReference
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 interfaceExtendedCollection<E>
- Specified by:
hasVolatileElements
in interfaceXGettingCollection<E>
- Returns:
true
if the collection contains volatile elements.

Description copied from interface:XGettingCollection
Returns the first contained element matching the passed sample as defined by the collection's equality logic or null, if no fitting element is contained. (For collections using referential equality, this method is basically just a variation ofXGettingCollection.contains(Object)
with a different return type. For collections with data-dependant equality, the returned element might be the same as the passed one or a data-wise equal one, depending on the content of the collection)- Specified by:
