Method Detail

copy
public XGettingSequence<E> copy()
Description copied from interface:XGettingSequenceCreates a true copy of this list which references th same elements in the same order as this list does at the time the method is called. The elements themselves are NOT copied (no deep copying).
The type of the returned list is the same as of this list if possible (i.e.: a SubList can not meaningful return a true copy that references its elements but still is a SubList)- Specified by:
copyin interfaceCopyable- Specified by:
copyin interfaceXGettingCollection<E>- Specified by:

-
containsId
public boolean containsId(E element)
Description copied from interface:XGettingCollectionSpecial version of contains() that guarantees to use identity comparison (" == ") when searching for the given element regardless of the collection's internal logic.
This method has the same behavior asXGettingCollection.containsSearched(Predicate)with aPredicateimplementation that checks for object identity. The only difference is a performance and usability advantage- Specified by:
containsIdin interfaceXGettingCollection<E>- Parameters:
element- the element to be searched in the collection by identity.- Returns:
- whether this collection contains exactely the given element.

Description copied from interface:XGettingCollectionReturnstrueif the passed collection is of the same type as this collection andthis.equalsContent(list, equalator)yieldstrue.- Specified by:
equalsin interfaceXGettingCollection<E>
-
equalsContent
public boolean equalsContent(XGettingCollection<? extends E> samples, Equalator<? super E> equalator)
Description copied from interface:XGettingCollectionReturnstrueif 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:
equalsContentin interfaceXGettingCollection<E>equalator- the equalator to use to determine the equality of each element- Returns:
trueif this list is equal to the passed list, false otherwise
-
except
public <T extends Consumer<? super E>> T except(XGettingCollection<? extends E> other, Equalator<? super E> equalator, T target)
- Specified by:
exceptin interfaceXGettingCollection<E>
-
hasVolatileElements
public boolean hasVolatileElements()
Description copied from interface:XGettingCollectionTells 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 areWeakReferenceofSoftReferenceor implementations of collection entries that remove the element contained in an entry by some means outside the collection.
Note thatWeakReferenceinstances 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:
hasVolatileElementsin interfaceExtendedCollection<E>- Specified by:
hasVolatileElementsin interfaceXGettingCollection<E>- Returns:
trueif the collection contains volatile elements.

-
seek
public E seek(E sample)
Description copied from interface:XGettingCollectionReturns 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:

-
maximumCapacity
public long maximumCapacity()
Description copied from interface:CapacityCarryingReturns the maximum amount of elements this carrier instance can contain.
The actual value may be depend on the configuration of the concrete instance or may depend only on the implementation of the carrier (meaning it is constant for all instances of the implementation, e.g.Integer.MAX_VALUE)- Specified by:

- the maximum amount of elements this carrier instance can contain.
