length - number of dummy elements to be inserted.

Throws:

IndexOutOfBoundsException - if index < 0 || index > size().

binarySearch

public int binarySearch(double key)

Searches the receiver for the specified value using the binary search algorithm. The receiver must must be sorted (as by the sort method) prior to making this call. If it is not sorted, the results are undefined: in particular, the call may enter an infinite loop. If the receiver contains multiple elements equal to the specified object, there is no guarantee which instance will be found.

Parameters:

key - the value to be searched for.

Returns:

index of the search key, if it is contained in the receiver; otherwise, (-(insertion point) - 1). The insertion point is defined as the the point at which the value would be inserted into the receiver: the index of the first element greater than the key, or receiver.size(), if all elements in the receiver 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

binarySearchFromTo

public int binarySearchFromTo(double key,
                     int from,
                     int to)

Searches the receiver for the specified value using the binary search algorithm. The receiver must must be sorted (as by the sort method) prior to making this call. If it is not sorted, the results are undefined: in particular, the call may enter an infinite loop. If the receiver contains multiple elements equal to the specified object, there is no guarantee which instance will be found.

Parameters:

key - the value to be searched for.

from - the leftmost search position, inclusive.

to - the rightmost search position, inclusive.

Returns:

index of the search key, if it is contained in the receiver; otherwise, (-(insertion point) - 1). The insertion point is defined as the the point at which the value would be inserted into the receiver: the index of the first element greater than the key, or receiver.size(), if all elements in the receiver 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.

elements

public double[] elements()

Returns the elements currently stored, possibly including invalid elements between size and capacity. WARNING: For efficiency reasons and to keep memory usage low, this method may decide not to copy the array. So if subsequently you modify the returned array directly via the [] operator, be sure you know what you're doing.

Returns:

the elements currently stored.

elements

public AbstractDoubleList elements(double[] elements)

Sets the receiver's elements to be the specified array. The size and capacity of the list is the length of the array. WARNING: For efficiency reasons and to keep memory usage low, this method may decide not to copy the array.

Parameters:

elements - the new elements to be stored.

Returns:

the receiver itself.

ensureCapacity

public abstract void ensureCapacity(int minCapacity)

Ensures that the receiver can hold at least the specified number of elements without needing to allocate new internal memory. If necessary, allocates new internal memory and increases the capacity of the receiver.

Parameters:

minCapacity - the desired minimum capacity.

equals

public boolean equals(Object otherObj)

Compares the specified Object with the receiver. Returns true if and only if the specified Object is also an ArrayList of the same type, both Lists have the same size, and all corresponding pairs of elements in the two Lists are identical. In other words, two Lists are defined to be equal if they contain the same elements in the same order.

Overrides:

equals in class Object

Parameters:

otherObj - the Object to be compared for equality with the receiver.

Returns:

true if the specified Object is equal to the receiver.

Applies a procedure to each element of the receiver, if any. Starts at index 0, moving rightwards.

Parameters:

procedure - the procedure to be applied. Stops iteration if the procedure returns false, otherwise continues.

Returns:

false if the procedure stopped before all elements where iterated over, true otherwise.

get

public double get(int index)

Returns the element at the specified position in the receiver.

Parameters:

index - index of element to return.

Throws:

IndexOutOfBoundsException - index is out of range (index < 0 || index >= size()).

getQuick

protected abstract double getQuick(int index)

Returns the element at the specified position in the receiver; WARNING: Does not check preconditions. Provided with invalid parameters this method may return invalid elements without throwing any exception! You should only use this method when you are absolutely sure that the index is within bounds. Precondition (unchecked): index >= 0 && index < size(). This method is normally only used internally in large loops where bounds are explicitly checked before the loop and need no be rechecked within the loop. However, when desperately, you can give this method public visibility in subclasses.

Parameters:

index - index of element to return.

indexOf

public int indexOf(double element)

Returns the index of the first occurrence of the specified element. Returns -1 if the receiver does not contain this element.

Parameters:

element - the element to be searched for.

Returns:

the index of the first occurrence of the element in the receiver; returns -1 if the element is not found.

indexOfFromTo

public int indexOfFromTo(double element,
                int from,
                int to)

IndexOutOfBoundsException - index is out of range (size()>0 && (from<0 || from>to || to>=size())).

lastIndexOf

public int lastIndexOf(double element)

Returns the index of the last occurrence of the specified element. Returns -1 if the receiver does not contain this element.

the index of the last occurrence of the element in the receiver; returns -1 if the element is not found.

lastIndexOfFromTo

public int lastIndexOfFromTo(double element,
                    int from,
                    int to)

Returns the index of the last occurrence of the specified element. Returns -1 if the receiver does not contain this element. Searches beginning at to, inclusive until from, inclusive. Tests for identity.

Parameters:

element - element to search for.

mergeSortFromTo

public void mergeSortFromTo(int from,
                   int to)

Sorts the specified range of the receiver into ascending order. The sorting algorithm is a modified mergesort (in which the merge is omitted if the highest element in the low sublist is less than the lowest element in the high sublist). This algorithm offers guaranteed n*log(n) performance, and can approach linear performance on nearly sorted lists.

You should never call this method unless you are sure that this particular sorting algorithm is the right one for your data set. It is generally better to call sort() or sortFromTo(...) instead, because those methods automatically choose the best sorting algorithm.

Specified by:

mergeSortFromTo in class AbstractList

Parameters:

from - the index of the first element (inclusive) to be sorted.

to - the index of the last element (inclusive) to be sorted.

Throws:

IndexOutOfBoundsException - index is out of range (size()>0 && (from<0 || from>to || to>=size())).

mergeSortFromTo

public void mergeSortFromTo(int from,
                   int to,
                   DoubleComparator c)

Sorts the receiver according to the order induced by the specified comparator. All elements in the range must be mutually comparable by the specified comparator (that is, c.compare(e1, e2) must not throw a ClassCastException for any elements e1 and e2 in the range).

This sort is guaranteed to be stable: equal elements will not be reordered as a result of the sort.

The sorting algorithm is a modified mergesort (in which the merge is omitted if the highest element in the low sublist is less than the lowest element in the high sublist). This algorithm offers guaranteed n*log(n) performance, and can approach linear performance on nearly sorted lists.

Parameters:

from - the index of the first element (inclusive) to be sorted.

to - the index of the last element (inclusive) to be sorted.

c - the comparator to determine the order of the receiver.

Throws:

ClassCastException - if the array contains elements that are not mutually comparable using the specified comparator.

IllegalArgumentException - if fromIndex > toIndex

ArrayIndexOutOfBoundsException - if fromIndex < 0 or toIndex > a.length

IndexOutOfBoundsException - index is out of range (size()>0 && (from<0 || from>to || to>=size())).

                            int to)

Returns a new list of the part of the receiver between from, inclusive, and to, inclusive.

Parameters:

from - the index of the first element (inclusive).

to - the index of the last element (inclusive).

Returns:

a new list

Throws:

IndexOutOfBoundsException - index is out of range (size()>0 && (from<0 || from>to || to>=size())).

quickSortFromTo

public void quickSortFromTo(int from,
                   int to)

Sorts the specified range of the receiver into ascending numerical order. The sorting algorithm is a tuned quicksort, adapted from Jon L. Bentley and M. Douglas McIlroy's "Engineering a Sort Function", Software-Practice and Experience, Vol. 23(11) P. 1249-1265 (November 1993). This algorithm offers n*log(n) performance on many data sets that cause other quicksorts to degrade to quadratic performance.

You should never call this method unless you are sure that this particular sorting algorithm is the right one for your data set. It is generally better to call sort() or sortFromTo(...) instead, because those methods automatically choose the best sorting algorithm.

Specified by:

quickSortFromTo in class AbstractList

Parameters:

from - the index of the first element (inclusive) to be sorted.

to - the index of the last element (inclusive) to be sorted.

Throws:

IndexOutOfBoundsException - index is out of range (size()>0 && (from<0 || from>to || to>=size())).

quickSortFromTo

public void quickSortFromTo(int from,
                   int to,
                   DoubleComparator c)

Sorts the receiver according to the order induced by the specified comparator. All elements in the range must be mutually comparable by the specified comparator (that is, c.compare(e1, e2) must not throw a ClassCastException for any elements e1 and e2 in the range).

The sorting algorithm is a tuned quicksort, adapted from Jon L. Bentley and M. Douglas McIlroy's "Engineering a Sort Function", Software-Practice and Experience, Vol. 23(11) P. 1249-1265 (November 1993). This algorithm offers n*log(n) performance on many data sets that cause other quicksorts to degrade to quadratic performance.

Parameters:

from - the index of the first element (inclusive) to be sorted.

to - the index of the last element (inclusive) to be sorted.

c - the comparator to determine the order of the receiver.

Throws:

ClassCastException - if the array contains elements that are not mutually comparable using the specified comparator.

IllegalArgumentException - if fromIndex > toIndex

ArrayIndexOutOfBoundsException - if fromIndex < 0 or toIndex > a.length

IndexOutOfBoundsException - index is out of range (size()>0 && (from<0 || from>to || to>=size())).

from - index of first element to be removed.

to - index of last element to be removed.

Throws:

IndexOutOfBoundsException - index is out of range (size()>0 && (from<0 || from>to || to>=size())).

                         int otherFrom)

Replaces a number of elements in the receiver with the same number of elements of another list. Replaces elements in the receiver, between from (inclusive) and to (inclusive), with elements of other, starting from otherFrom (inclusive).

Parameters:

from - the position of the first element to be replaced in the receiver

to - the position of the last element to be replaced in the receiver

If from > to, then inserts other part before from.

Parameters:

from - the first element of the receiver (inclusive)

to - the last element of the receiver (inclusive)

other - the other list (may be identical with receiver)

otherFrom - the first element of the other list (inclusive)

Replaces the element at the specified position in the receiver with the specified element; WARNING: Does not check preconditions. Provided with invalid parameters this method may access invalid indexes without throwing any exception! You should only use this method when you are absolutely sure that the index is within bounds. Precondition (unchecked): index >= 0 && index < size(). This method is normally only used internally in large loops where bounds are explicitly checked before the loop and need no be rechecked within the loop. However, when desperately, you can give this method public visibility in subclasses.

Parameters:

index - index of element to replace.

element - element to be stored at the specified position.

setSizeRaw

protected void setSizeRaw(int newSize)

Sets the size of the receiver without modifying it otherwise. This method should not release or allocate new memory but simply set some instance variable like size. If your subclass overrides and delegates size changing methods to some other object, you must make sure that those overriding methods not only update the size of the delegate but also of this class. For example: public DatabaseList extends AbstractDoubleList { ... public void removeFromTo(int from,int to) { myDatabase.removeFromTo(from,to); this.setSizeRaw(size-(to-from+1)); } }

shuffleFromTo

public void shuffleFromTo(int from,
                 int to)

Randomly permutes the part of the receiver between from (inclusive) and to (inclusive).

Specified by:

shuffleFromTo in class AbstractList

Parameters:

from - the index of the first element (inclusive) to be permuted.

to - the index of the last element (inclusive) to be permuted.

Throws:

IndexOutOfBoundsException - index is out of range (size()>0 && (from<0 || from>to || to>=size())).

size

public int size()

Returns the number of elements contained in the receiver.

Specified by:

size in class AbstractCollection

times

public AbstractDoubleList times(int times)

Returns a list which is a concatenation of times times the receiver.

Parameters:

times - the number of times the receiver shall be copied.

toList

public ArrayList toList()

Returns a java.util.ArrayList containing all the elements in the receiver.

Specified by:

toList in class AbstractCollection

toString

public String toString()

Returns a string representation of the receiver, containing the String representation of each element.

Overrides:
