Constructor Detail

HashArrayList

public HashArrayList()

public HashArrayList(Collection<? extends E> c)

Creates a new HashArrayList object from a specified Collection.

Parameters:

c - Collection

HashArrayList

public HashArrayList(int initialCapacity)

Constructs an empty HashArrayList with the specified initial capacity.

Parameters:

initialCapacity - the initial capacity of the list

Method Detail

add

public boolean add(E e)

Appends the specified Element to the end of Arraylist and adds the specified Element to the HashSet if it is not already present.

Specified by:

add in interface Collection<E>

Specified by:

add in interface List<E>

Overrides:

add in class ArrayList<E>

Parameters:

e - Element, which should get append

Returns:

True

See Also:

ArrayList.add(java.lang.Object), HashSet.add(java.lang.Object)

add

public void add(int index,
                E element)

Appends the specified Element to the specified index.Shifts the element currently at that position (if any) and any subsequent elements to the right (adds one to their indices). Adds the specified element to the HashSet if it is not already present.

Specified by:

add in interface List<E>

Overrides:

add in class ArrayList<E>

Parameters:

index - index, where the Element should be placed to

element - Element to be appended

See Also:

ArrayList.add(int, java.lang.Object), HashSet.add(java.lang.Object)

addAll

public boolean addAll(Collection<? extends E> c)

This implementation iterates over the specified Collection, and adds each object returned by the iterator to this collection, in turn. Appends the new Objects to the end of the ArrayList

Specified by:

addAll in interface Collection<E>

Specified by:

addAll in interface List<E>

Overrides:

addAll in class ArrayList<E>

Parameters:

c - Collection

Returns:

true if this list changed as a result of the call

See Also:

ArrayList.addAll(java.util.Collection), AbstractCollection.addAll(java.util.Collection)

addAll

public boolean addAll(int index,
                      Collection<? extends E> c)

This implementation iterates over the specified Collection, and adds each object returned by the iterator to this collection, in turn. Inserts all of the elements in the specified collection into the ArrayList, starting at the specified position. Shifts the element currently at that position.

Specified by:

addAll in interface List<E>

Overrides:

addAll in class ArrayList<E>

Parameters:

index - startindex

c - Collection

Returns:

true if this list changed as a result of the call

See Also:

ArrayList.addAll(int, java.util.Collection), AbstractCollection.addAll(java.util.Collection)

clear

public void clear()

Removes all of the elements from this HashArrayList. The ArrayList and the HashSet will be empty after this call returns.

Specified by:

clear in interface Collection<E>

Specified by:

clear in interface List<E>

Overrides:

clear in class ArrayList<E>

See Also:

ArrayList.clear(), HashSet.clear()

clone

public Object clone()

Clones the HashArrayList.

Overrides:

clone in class ArrayList<E>

Returns:

the cloned HashArrayList

contains

public boolean contains(Object o)

Tests whether the ArrayList contains the specified Object or not.

Specified by:

contains in interface Collection<E>

Specified by:

contains in interface List<E>

Overrides:

contains in class ArrayList<E>

Parameters:

o - Object to be tested

Returns:

True, if the ArrayList contains the specified Object

See Also:

ArrayList.contains(java.lang.Object)

remove

public E remove(int index)

Removes the Object on the specified index. The ArrayList shifts any subsequent elements to the left.Removes the element associated with the index in the Hashmap //Note: If the deleted Object was multiple time inside the Arraylist, it could be possible that the Object is inside ArrayList, but not in the HashSet

Specified by:

remove in interface List<E>

Overrides:

remove in class ArrayList<E>

Parameters:

index - index, whose Object to be deleted

Returns:

the Object, that was removed from the HashArrayList

See Also:

ArrayList.remove(int), HashSet.remove(java.lang.Object)

remove

public boolean remove(Object o)

Removes the Object on the specified index. The ArrayList deletes the first occurrence of the specified Object and shifts any subsequent elements to the left.Removes the element associated with the index in the Hashmap //Note: If the deleted Object was multiple time inside the Arraylist, it could be possible that the Object is inside ArrayList, but not in the HashSet

Specified by:

remove in interface Collection<E>

Specified by:

remove in interface List<E>

Overrides:

remove in class ArrayList<E>

Parameters:

o - Object to be deleted

Returns:

the Object, that was removed from the HashArrayList

See Also:

ArrayList.remove(java.lang.Object), HashSet.remove(java.lang.Object)

removeRange

protected void removeRange(int fromIndex,
                           int toIndex)

Removes the Object on the index within the specified range. The ArrayList shifts any subsequent elements to the left.Removes the element associated with the index in the Hashmap //Note: If the deleted Object was multiple time inside the Arraylist, it could be possible that the Object is inside ArrayList, but not in the HashSet

Overrides:

removeRange in class ArrayList<E>

Parameters:

fromIndex - Start IndexRange

toIndex - End IndexRange

See Also:

ArrayList.removeRange(int, int), HashSet.remove(java.lang.Object)

set

public E set(int index,
             E element)

Replaces the element at the specified position in this ArrayList with the specified element. Removes the element associated with the index in the Hashmap and adds the element.

Specified by:

set in interface List<E>

Overrides:

set in class ArrayList<E>

index - index, whose element to be replaced

element - element

Returns:

the element previously at the specified position
