Record Components:: type - of elements stored in the list

All Implemented Interfaces:: Serializable, Cloneable, ILongListable

Direct Known Subclasses:: LongBigList.LongBlock, LongGapList.ReadOnlyList

public class LongGapList extends ILongList

Class {link LongGapList} combines the strengths of both ArrayList and LinkedList. It is implemented to offer both efficient random access to elements by index (as ArrayList does) and at the same time efficient adding and removing elements to and from beginning and end (as LinkedList does). It also exploits the locality of reference often seen in applications to further improve performance, e.g. for iterating over the list.

The class can be used as drop-in replacement for ArrayList. It is also source compatible to LinkedList/Deque as it implements all needed methods. It cannot implement Deque however, use

invalid reference

#asDeque

to get a view implementing it.

Note that this implementation is not synchronized.

Note that the iterators provided are not fail-fast.

  Parameters:
  
  array - array to store the list elements
  
  index - index of first element to copy
  
  len - number of elements to copy
- writeObject
  
  private void writeObject(ObjectOutputStream oos) throws IOException
  
  Serialize a LongGapList object.
  
  Parameters:
  
  oos - output stream for serialization
  
  Throws:
  
  IOException - if serialization fails
- readObject
  
  private void readObject(ObjectInputStream ois) throws IOException, ClassNotFoundException
  
  Deserialize a LongGapList object.
  
  Parameters:
  
  ois - input stream for serialization
  
  Throws:
  
  IOException - if serialization fails
  
  ClassNotFoundException - if serialization fails
- doCreate
  
  public LongGapList doCreate(int capacity)
  
  Description copied from class: ILongList
  
  Create list with specified capacity.
  
  Specified by:
  
  doCreate in class ILongList
  
  Parameters:
  
  capacity - initial capacity (use -1 for default capacity)
  
  Returns:
  
  created list
- doRemoveAll
  
  protected void doRemoveAll(int index, int len)
  
  Description copied from class: ILongList
  
  Remove specified range of elements from list.
  
  Overrides:
  
  doRemoveAll in class ILongList
  
  Parameters:
  
  index - index of first element to remove
  
  len - number of elements to remove
- doRemoveAllFast
  
  protected boolean doRemoveAllFast(int index, int len)
  
  Remove specified range of elements from list as specialized fast operation.
  
  Parameters:
  
  index - index of first element to remove
  
  len - number of elements to remove
  
  Returns:
  
  true if removal could be done, false otherwise
- sort
  
  public void sort(int index, int len)
  
  Description copied from class: ILongList
  
  Sort specified elements in the list using the specified comparator.
  Specified by:
  
  sort in class ILongList
  
  Parameters:
  
  index - index of first element to sort
  
  len - number of elements to sort
  
  See Also:
  
  Arrays.sort(int[])
- binarySearch
  
  public int binarySearch(int index, int len, long key)
  
  Description copied from class: ILongList
  Searches the specified range for an object using the binary search algorithm.
  Note that the method is defined to work with an arbitrary type <K>. This allows to search directly for a key field in the object without the need to construct an object containing the key:
  persons.binarySearch("john", new SearchByName()); class SearchByName implements Comparator<Object> { public int compare(Object o1, Object o2) { String s1 = (o1 instanceof String) ? (String) o1 : ((Name) o1).getName(); String s2 = (o2 instanceof String) ? (String) o2 : ((Name) o2).getName(); return s1.compareTo(s2); } }/
  Specified by:
  
  binarySearch in class ILongList
  
  Parameters:
  
  index - index of first element to search
  
  len - number of elements to search
  
  key - the value to be searched for
  
  Returns:
  
  index of the search key, if it is contained in the array; otherwise, (-(insertion point) - 1). The insertion point is defined as the point at which the key would be inserted into the array: the index of the first element greater than the key, or a.length if all elements in the array are less than the specified key. Note that this guarantees that the return value will be >= 0 if and only if the key is found.

  Arrays.binarySearch(long[], long)
- debugCheck
  
  private void debugCheck()
  
  Private method to check invariant of LongGapList. It is only used for debugging.
- debugState
  
  private int debugState()
  
  Private method to determine state of LongGapList. It is only used for debugging.
  
  Returns:
  
  state in which LongGapList is
- debugDump
  
  private void debugDump()
  
  Private method to dump fields of LongGapList. It is only called if the code is run in development mode.
- debugPrint
  
  private String debugPrint(long[] values)
  
  Print array values into string.
  
  Parameters:
  
  values - array with values
  
  Returns:
  
  string representing array values
- debugLog
  
  private void debugLog(String msg)
  
  Private method write logging output. It is only used for debugging.
  
  Parameters:
  
  msg - message to write out
