Method Detail

clear

public void clear()

Removes all of the elements from this Collection by clearing the underlying Map.

Specified by:

clear in interface Collection<V>

Overrides:

clear in class AbstractCollection<V>

contains

public boolean contains(Object o)

Returns true if this collection contains the specified element. More formally, returns true if and only if this collection contains at least one element e such that (o==null ? e==null : o.equals(e)).

Specified by:

contains in interface Collection<V>

Overrides:

contains in class AbstractCollection<V>

Parameters:

o - object to be checked for containment in this collection

Returns:

true if this collection contains the specified element

isEmpty

public boolean isEmpty()

Returns true if this Set is empty.

Specified by:

isEmpty in interface Collection<V>

Overrides:

isEmpty in class AbstractCollection<V>

Returns:

true if this Set is empty

iterator

public Iterator<V> iterator()

Returns an iterator over the elements contained in this collection.

Specified by:

iterator in interface Iterable<V>

Specified by:

iterator in interface Collection<V>

Specified by:

iterator in class AbstractCollection<V>

Returns:

an iterator over the elements contained in this collection

remove

public boolean remove(Object o)

Removes the specified element from this Collection of values if it is present by removing the associated key/value mapping from the underlying Map.

Specified by:

remove in interface Collection<V>

Overrides:

remove in class AbstractCollection<V>

Parameters:

o - object to be removed from this Collection, if present

Returns:

true if the Collection contained the specified element

size

public int size()

Returns the number of elements in this collection.

Specified by:

size in interface Collection<V>

Specified by:

size in class AbstractCollection<V>

Returns:

the number of elements in this collection

instantiateIterator

protected Iterator<V> instantiateIterator()

Factory pattern: Create a values Iterator.

Returns:

a new instance of an Iterator over the values Collection
