Field Detail

• STRICT_SORT_ORDER

  public static final int STRICT_SORT_ORDER

  Sorting mode where elements are always in sorted order, even if this requires that elements be moved from one index to another when their value is changed.

  Constant Field Values

• AVOID_MOVING_ELEMENTS

  public static final int AVOID_MOVING_ELEMENTS

  Sorting mode where elements aren't moved when their value is changed, even if this means they are no longer in perfect sorted order. This mode is useful in editable lists and tables because it is annoying for the current element to move if its value changes.

  Constant Field Values

Constructor Detail

• SortedList

  public SortedList(EventList<E> source)

  Creates a SortedList that sorts the specified EventList. Because this constructor takes no Comparator argument, all elements in the specified EventList must implement Comparable or a ClassCastException will be thrown.

  Usage of factory method create(EventList) is preferable.

  Parameters:

  source - the EventList to be sorted

• SortedList

  public SortedList(EventList<E> source,
                    java.util.Comparator<? super E> comparator)

  Creates a SortedList that sorts the specified EventList using the specified Comparator to determine sort order. If the specified Comparator is null, then this List will be unsorted.

Method Detail

• create

  public static <E extends java.lang.Comparable<? super E>> SortedList<E> create(EventList<E> source)

  Creates a SortedList that sorts the specified EventList. All elements in the specified EventList must implement Comparable.

  Parameters:

  source - the EventList to be sorted

• setMode

  public void setMode(int mode)

  Modify the behaviour of this SortedList to one of the predefined modes.

  Parameters:

  mode - either STRICT_SORT_ORDER or AVOID_MOVING_ELEMENTS.

• getMode

  public int getMode()

  Get the behaviour mode for this SortedList.

  Returns:

  one of STRICT_SORT_ORDER (default) or AVOID_MOVING_ELEMENTS.

• listChanged

  public void listChanged(ListEvent<E> listChanges)

  When the underlying list changes, this notification allows the object to repaint itself or update itself as necessary.

  It is mandatory that the calling thread has obtained the write lock on the source list. This is because the calling thread will have written to the source list to cause this event. This condition guarantees that no writes can occur while the listener is handling this event. It is an error to write to the source list while processing an event.

  Specified by:

  listChanged in interface ListEventListener<E>

  Specified by:

  listChanged in class TransformedList<E,E>

  Parameters:

  listChanges - a ListEvent describing the changes to the list

• getSourceIndex

  protected int getSourceIndex(int mutationIndex)

  Gets the index in the source EventList that corresponds to the specified index. More formally, returns the index such that
  this.get(i) == source.get(getSourceIndex(i)) for all legal values of i.

  Overrides:

  getSourceIndex in class TransformedList<E,E>

• isWritable

  protected boolean isWritable()

  Gets whether the source EventList is writable via this API.

  Extending classes must override this method in order to make themselves writable.

  Specified by:

  isWritable in class TransformedList<E,E>

• getComparator

  public java.util.Comparator<? super E> getComparator()

  Gets the Comparator that is being used to sort this list.

  Returns:

  the Comparator in use, or null if this list is currently unsorted. If this is an EventList of Comparable elements in natural order, then a ComparableComparator} will be returned.

• setComparator

  public void setComparator(java.util.Comparator<? super E> comparator)

  Set the Comparator in use in this EventList. This will sort the source EventList into a new order.

  Performance Note: sorting will take O(N * Log N) time.

  Warning: This method is thread ready but not thread safe. See EventList for an example of thread safe code.

  Parameters:

  comparator - the Comparator to specify how to sort the list. If the source EventList elements implement Comparable, you may use a GlazedLists.comparableComparator() to sort them in their natural order. You may also specify null to put this SortedList in unsorted order.

• indexOf

  public int indexOf(java.lang.Object object)

  Returns the index in this list of the first occurrence of the specified element, or -1 if this list does not contain this element. More formally, returns the lowest index i such that (o==null ? get(i)==null : o.equals(get(i))), or -1 if there is no such index.

  Specified by:

  indexOf in interface java.util.List<E>

  Overrides:

  indexOf in class AbstractEventList<E>

  Parameters:

  object - element to search for.

  Returns:

  the index in this list of the first occurrence of the specified element, or -1 if this list does not contain this element.

• lastIndexOf

  public int lastIndexOf(java.lang.Object object)

  Returns the index in this list of the last occurrence of the specified element, or -1 if this list does not contain this element. More formally, returns the highest index i such that (o==null ? get(i)==null : o.equals(get(i))), or -1 if there is no such index.

  Specified by:

  lastIndexOf in interface java.util.List<E>

  Overrides:

  lastIndexOf in class AbstractEventList<E>

  Parameters:

  object - element to search for.

  Returns:

  the index in this list of the last occurrence of the specified element, or -1 if this list does not contain this element.

• sortIndex

  public int sortIndex(java.lang.Object object)

  Returns the first index of the object's sort location or the first index at which the object could be positioned if inserted.

  Unlike indexOf(java.lang.Object) this method does not guarantee the given object equals the element at the returned index. Instead, they are indistinguishable according to the sorting Comparator.

  Returns:

  a value in [0, size()] inclusive

• lastSortIndex

  public int lastSortIndex(java.lang.Object object)

  Returns the last index of the object's sort location or the last index at which the object could be positioned if inserted.

  Unlike lastIndexOf(java.lang.Object) this method does not guarantee the given object equals the element at the returned index. Instead, they are indistinguishable according to the sorting Comparator.

  Returns:

  a value in [0, size()] inclusive

• indexOfSimulated

  public int indexOfSimulated(java.lang.Object object)

  Deprecated. Deprecated as of 12/11/2005. Replaced with sortIndex(Object) which has cleaner semantics.
  Returns the index in this list of the first occurrence of the specified element, or the index where that element would be in the list if it were inserted.

  Returns:

  the index in this list of the first occurrence of the specified element, or the index where that element would be in the list if it were inserted. This will return a value in [0, size()], inclusive.

• contains

  public boolean contains(java.lang.Object object)

  Returns true if this list contains the specified element. More formally, returns true if and only if this list contains at least one element e such that (o==null ? e==null : o.equals(e)).

  Specified by:

  contains in interface java.util.Collection<E>

  Specified by:

  contains in interface java.util.List<E>

  Overrides:

  contains in class AbstractEventList<E>

  Parameters:

  object - element whose presence in this list is to be tested.

  Returns:

  true if this list contains the specified element.

• iterator

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

  Returns an iterator over the elements in this list in proper sequence.

  The returned Iterator will become inconsistent if the EventList that it views is modified. To overcome this problem, use AbstractEventList.listIterator(). When used concurrently, the returned Iterator requires locking via this list's ReadWriteLock.

  Specified by:

  iterator in interface java.lang.Iterable<E>

  Specified by:

  iterator in interface java.util.Collection<E>

  Specified by:

  iterator in interface java.util.List<E>

  Overrides:

  iterator in class AbstractEventList<E>

  Returns:

  an iterator over the elements in this list in proper sequence.
