Returns:

true if this big list changed as a result of the call

See Also:

List.addAll(int, Collection)

addAll

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

Description copied from class: AbstractShortBigList

Adds all of the elements in the specified collection to this collection (optional operation). The behavior of this operation is undefined if the specified collection is modified while the operation is in progress. (This implies that the behavior of this call is undefined if the specified collection is this collection, and this collection is nonempty.)

This implementation iterates over the specified collection, and adds each object returned by the iterator to this collection, in turn.

Note that this implementation will throw an UnsupportedOperationException unless add is overridden (assuming the specified collection is non-empty).

This implementation delegates to the type-specific version of BigList.addAll(long, Collection).

Specified by:

addAll in interface Collection<Short>

Overrides:

addAll in class AbstractShortBigList

Parameters:

c - collection containing elements to be added to this collection

Returns:

true if this collection changed as a result of the call

See Also:

AbstractCollection.add(Object)

removeAll

public boolean removeAll(Collection<?> c)

Description copied from class: java.util.AbstractCollection

Removes all of this collection's elements that are also contained in the specified collection (optional operation). After this call returns, this collection will contain no elements in common with the specified collection.

This implementation iterates over this collection, checking each element returned by the iterator in turn to see if it's contained in the specified collection. If it's so contained, it's removed from this collection with the iterator's remove method.

Note that this implementation will throw an UnsupportedOperationException if the iterator returned by the iterator method does not implement the remove method and this collection contains one or more elements in common with the specified collection.

Specified by:

removeAll in interface Collection<Short>

Overrides:

removeAll in class AbstractCollection<Short>

Parameters:

c - collection containing elements to be removed from this collection

Returns:

true if this collection changed as a result of the call

See Also:

AbstractCollection.remove(Object), AbstractCollection.contains(Object)

retainAll

public boolean retainAll(Collection<?> c)

Description copied from class: java.util.AbstractCollection

Retains only the elements in this collection that are contained in the specified collection (optional operation). In other words, removes from this collection all of its elements that are not contained in the specified collection.

This implementation iterates over this collection, checking each element returned by the iterator in turn to see if it's contained in the specified collection. If it's not so contained, it's removed from this collection with the iterator's remove method.

Note that this implementation will throw an UnsupportedOperationException if the iterator returned by the iterator method does not implement the remove method and this collection contains one or more elements not present in the specified collection.

Specified by:

retainAll in interface Collection<Short>

Overrides:

retainAll in class AbstractCollection<Short>

Parameters:

c - collection containing elements to be retained in this collection

Returns:

true if this collection changed as a result of the call

See Also:

AbstractCollection.remove(Object), AbstractCollection.contains(Object)

addAll

public boolean addAll(ShortBigList c)

Description copied from class: AbstractShortBigList

Appends all of the elements in the specified type-specific big list to the end of this type-specific big list (optional operation).

This implementation delegates to the type-specific list version of AbstractShortBigList.addAll(long, Collection).

Specified by:

addAll in interface ShortBigList

Overrides:

addAll in class AbstractShortBigList

See Also:

List.addAll(int,java.util.Collection)

addAll

public boolean addAll(long i,
                      ShortBigList c)

Description copied from class: AbstractShortBigList

Inserts all of the elements in the specified type-specific big list into this type-specific big list at the specified position (optional operation).

This implementation delegates to the type-specific version of AbstractShortBigList.addAll(long, Collection).

Specified by:

addAll in interface ShortBigList

Overrides:

addAll in class AbstractShortBigList

See Also:

List.addAll(int,java.util.Collection)

Adds all elements of the given type-specific collection to this collection.

This implementation delegates to the type-specific version of AbstractShortBigList.addAll(long, Collection).

Specified by:

addAll in interface ShortCollection

Overrides:

addAll in class AbstractShortBigList

Parameters:

c - a type-specific collection.

Returns:

true if this collection changed as a result of the call.

See Also:

Collection.addAll(Collection)

removeAll

public boolean removeAll(ShortCollection c)

Description copied from interface: ShortCollection

Remove from this collection all elements in the given type-specific collection.

Specified by:

removeAll in interface ShortCollection

Overrides:

removeAll in class AbstractShortCollection

Parameters:

c - a type-specific collection.

Returns:

true if this collection changed as a result of the call.

See Also:

retainAll

public boolean retainAll(ShortCollection c)

Description copied from interface: ShortCollection

Retains in this collection only elements from the given type-specific collection.

Specified by:

retainAll in interface ShortCollection

Overrides:

retainAll in class AbstractShortCollection

Parameters:

c - a type-specific collection.

Returns:

true if this collection changed as a result of the call.

See Also:

Collection.retainAll(Collection)

clear

public void clear()

Description copied from class: AbstractShortBigList

Removes all of the elements from this collection (optional operation). The collection will be empty after this method returns.

This implementation iterates over this collection, removing each element using the Iterator.remove operation. Most implementations will probably choose to override this method for efficiency.

Note that this implementation will throw an UnsupportedOperationException if the iterator returned by this collection's iterator method does not implement the remove method and this collection is non-empty.

This implementation delegates to AbstractShortBigList.removeElements(long, long).

Specified by:

clear in interface Collection<Short>

Overrides:

clear in class AbstractShortBigList

size64

public long size64()

Description copied from interface: Size64

Returns the size of this data structure as a long.

Specified by:

size64 in interface Size64

Returns:

the size of this data structure.

clone

public Object clone()

Description copied from class: java.lang.Object

Creates and returns a copy of this object. The precise meaning of "copy" may depend on the class of the object. The general intent is that, for any object x, the expression:

 x.clone() != x

will be true, and that the expression:

 x.clone().getClass() == x.getClass()

will be true, but these are not absolute requirements. While it is typically the case that:

 x.clone().equals(x)

will be true, this is not an absolute requirement.

By convention, the returned object should be obtained by calling super.clone. If a class and all of its superclasses (except Object) obey this convention, it will be the case that x.clone().getClass() == x.getClass().

By convention, the object returned by this method should be independent of this object (which is being cloned). To achieve this independence, it may be necessary to modify one or more fields of the object returned by super.clone before returning it. Typically, this means copying any mutable objects that comprise the internal "deep structure" of the object being cloned and replacing the references to these objects with references to the copies. If a class contains only primitive fields or references to immutable objects, then it is usually the case that no fields in the object returned by super.clone need to be modified.

The method clone for class Object performs a specific cloning operation. First, if the class of this object does not implement the interface Cloneable, then a CloneNotSupportedException is thrown. Note that all arrays are considered to implement the interface Cloneable and that the return type of the clone method of an array type T[] is T[] where T is any reference or primitive type. Otherwise, this method creates a new instance of the class of this object and initializes all its fields with exactly the contents of the corresponding fields of this object, as if by assignment; the contents of the fields are not themselves cloned. Thus, this method performs a "shallow copy" of this object, not a "deep copy" operation.

The class Object does not itself implement the interface Cloneable, so calling the clone method on an object whose class is Object will result in throwing an exception at run time.

Overrides:

clone in class Object

Returns:

a clone of this instance.
