Class AbstractDoubleCollection

java.lang.Object
  it.unimi.dsi.fastutil.doubles.AbstractDoubleCollection

All Implemented Interfaces:

Collection, DoubleCollection

Direct Known Subclasses:

AbstractDoubleList, AbstractDoubleSet

public abstract class AbstractDoubleCollection

extends Object

implements DoubleCollection

An abstract class providing basic methods for collections implementing a type-specific interface.

In particular, this class provide iterator(), add(Object), remove(Object) and contains(Object) methods that just call the type-specific counterpart.

Method Summary

boolean	add(double k)
boolean	add(Object o) Delegates to the corresponding type-specific method.
boolean	addAll(Collection c) Adds all elements of the given collection to this collection.
boolean	addAll(DoubleCollection c) Adds all elements of the given type-specific collection to this collection.
void	clear()
boolean	contains(Object o) Delegates to the corresponding type-specific method.
boolean	containsAll(Collection c) Checks whether this collection contains all elements from the given collection.
boolean	containsAll(DoubleCollection c) Checks whether this collection contains all elements from the given type-specific collection.
boolean	isEmpty()
Iterator	iterator() Delegates to the corresponding type-specific method.
boolean	rem(double k) Note that this method should be called remove(), but the clash with the similarly named index-based method in the List interface forces us to use a distinguished name.
boolean	rem(Object o) Delegates to the corresponding type-specific method.
boolean	remove(Object ok)
boolean	removeAll(Collection c) Remove from this collection all elements in the given collection.
boolean	removeAll(DoubleCollection c) Remove from this collection all elements in the given type-specific collection.
boolean	retainAll(Collection c) Retains in this collection only elements from the given collection.
boolean	retainAll(DoubleCollection c) Retains in this collection only elements from the given type-specific collection.
Object[]	toArray()
double[]	toArray(double[] a) Builds a primitive type array containing the items of this collection.
Object[]	toArray(Object[] a)
double[]	toDoubleArray() Returns a primitive type array containing the items of this collection.
double[]	toDoubleArray(double[] a) Builds a primitive type array containing the items of this collection.
String	toString()

Method Detail

toArray

public double[] toArray(double[] a)

Description copied from interface: DoubleCollection

Builds a primitive type array containing the items of this collection.

Specified by:

toArray in interface DoubleCollection

Parameters:

a - if this array is big enough, it will be used to store the collection.

Returns:

a primitive type array containing the items of this collection.

See Also:

Collection.toArray(Object[])

toDoubleArray

public double[] toDoubleArray()

Description copied from interface: DoubleCollection

Returns a primitive type array containing the items of this collection.

Specified by:

toDoubleArray in interface DoubleCollection

Returns:

a primitive type array containing the items of this collection.

See Also:

Collection.toArray()

toDoubleArray

public double[] toDoubleArray(double[] a)

Description copied from interface: DoubleCollection

Builds a primitive type array containing the items of this collection.

Specified by:

toDoubleArray in interface DoubleCollection

Parameters:

a - if this array is big enough, it will be used to store the collection.

Returns:

a primitive type array containing the items of this collection.

See Also:

Collection.toArray(Object[])

addAll

public boolean addAll(DoubleCollection c)

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

Specified by:

addAll in interface DoubleCollection

Parameters:

c - a type-specific collection.

Returns:

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

See Also:

Collection.addAll(Collection)

containsAll

public boolean containsAll(DoubleCollection c)

Checks whether this collection contains all elements from the given type-specific collection.

Specified by:

containsAll in interface DoubleCollection

Parameters:

c - a type-specific collection.

Returns:

true if this collection contains all elements of the argument.

See Also:

Collection.containsAll(Collection)

retainAll

public boolean retainAll(DoubleCollection c)

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

Specified by:

retainAll in interface DoubleCollection

Parameters:

c - a type-specific collection.

Returns:

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

See Also:

Collection.retainAll(Collection)

removeAll

public boolean removeAll(DoubleCollection c)

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

Specified by:

removeAll in interface DoubleCollection

Parameters:

c - a type-specific collection.

Returns:

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

See Also:

Collection.removeAll(Collection)

toArray

public Object[] toArray()

Specified by:

toArray in interface Collection

toArray

public Object[] toArray(Object[] a)

Specified by:

toArray in interface Collection

addAll

public boolean addAll(Collection c)

Adds all elements of the given collection to this collection.

Specified by:

addAll in interface Collection

Parameters:

c - a collection.

Returns:

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

add

public boolean add(double k)

Specified by:

add in interface DoubleCollection

See Also:

Collection.add(Object)

rem

public boolean rem(double k)

Description copied from interface: DoubleCollection

Note that this method should be called remove(), but the clash with the similarly named index-based method in the List interface forces us to use a distinguished name. For simplicity, the set interfaces reinstates remove().

Specified by:

rem in interface DoubleCollection

See Also:

Collection.remove(Object)

remove

public boolean remove(Object ok)

Specified by:

remove in interface Collection

clear

public void clear()

Specified by:

clear in interface Collection

iterator

public Iterator iterator()

Delegates to the corresponding type-specific method.

Specified by:

iterator in interface Collection

add

public boolean add(Object o)

Delegates to the corresponding type-specific method.

Specified by:

add in interface Collection

rem

public boolean rem(Object o)

Delegates to the corresponding type-specific method.

contains

public boolean contains(Object o)

Delegates to the corresponding type-specific method.

Specified by:

contains in interface Collection

containsAll

public boolean containsAll(Collection c)

Checks whether this collection contains all elements from the given collection.

Specified by:

containsAll in interface Collection

Parameters:

c - a collection.

Returns:

true if this collection contains all elements of the argument.

retainAll

public boolean retainAll(Collection c)

Retains in this collection only elements from the given collection.

Specified by:
