The class of value stored in the Map.

Constructor Detail

RestrictedEntrySet

public RestrictedEntrySet(Set set,
                          Class clzKey,
                          Class clzVal)

Constructor.

Parameters:

set - the underlying Entry Set

clzKey - the class of keys that may be stored in the Map

clzVal - the class of values that may be stored in the Map

Method Detail

size

public int size()

Returns the number of elements in this Collection.

Specified by:

size in interface Collection

Specified by:

size in interface Set

Returns:

the number of elements in this Collection

isEmpty

public boolean isEmpty()

Returns true if this Collection contains no elements.

Specified by:

isEmpty in interface Collection

Specified by:

isEmpty in interface Set

Returns:

true if this Collection contains no elements

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

Specified by:

contains in interface Set

Parameters:

o - the object to search for in the Collection

Returns:

true if this Collection contains the specified object

iterator

public Iterator iterator()

Returns an Iterator over the elements contained in this Collection.

Specified by:

iterator in interface Collection

Specified by:

iterator in interface Iterable

Specified by:

iterator in interface Set

Returns:

an Iterator over the elements contained in this Collection

toArray

public Object[] toArray()

Returns an array containing all of the elements in this Collection. Obeys the general contract of Collection.toArray.

Specified by:

toArray in interface Collection

Specified by:

toArray in interface Set

Returns:

an array, whose component type is the class of objects that may be stored in the Collection containing all of the elements in this Collection

toArray

public Object[] toArray(Object[] ao)

Returns an array containing all of the elements in this Collection whose runtime type is that of the specified array. Obeys the general contract of Collection.toArray.

Specified by:

toArray in interface Collection

Specified by:

toArray in interface Set

Parameters:

ao - the array into which the elements of this Collection are to be stored, if it is big enough; otherwise, a new array of the same runtime type is allocated for this purpose

Returns:

an array containing the elements of this Collection

add

public boolean add(Object o)

Ensures that this Collection contains the specified element.

Specified by:

add in interface Collection

Specified by:

add in interface Set

Parameters:

o - element whose presence in this Collection is to be ensured

Returns:

true if the Collection changed as a result of the call

remove

public boolean remove(Object o)

Removes a single instance of the specified element from this Collection, if it is present (optional operation). More formally, removes an element e such that (o==null ? e==null : o.equals(e)), if the Collection contains one or more such elements. Returns true if the Collection contained the specified element (or equivalently, if the Collection changed as a result of the call).

Specified by:

remove in interface Collection

Specified by:

remove in interface Set

Parameters:

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

Returns:

true if the Collection contained the specified element

containsAll

public boolean containsAll(Collection col)

Returns true if this Collection contains all of the elements in the specified Collection.

Specified by:

containsAll in interface Collection

Specified by:

containsAll in interface Set

Parameters:

col - Collection to be checked for containment in this Collection

Returns:

true if this Collection contains all of the elements in the specified Collection

addAll

public boolean addAll(Collection col)

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.)

Specified by:

addAll in interface Collection

Specified by:

addAll in interface Set

Parameters:

col - elements to be inserted into this Collection

Returns:

true if this Collection changed as a result of the call

removeAll

public boolean removeAll(Collection col)

Removes all 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.

Specified by:

removeAll in interface Collection

Specified by:

removeAll in interface Set

Parameters:

col - elements to be removed from this Collection

Returns:

true if this Collection changed as a result of the call

retainAll

public boolean retainAll(Collection col)

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.

Specified by:

retainAll in interface Collection

Specified by:

retainAll in interface Set

Parameters:

col - elements to be retained in this Collection

Returns:

true if this Collection changed as a result of the call

clear

public void clear()

Removes all of the elements from this Collection.

Specified by:

clear in interface Collection

Specified by:

clear in interface Set

equals

public boolean equals(Object o)

Compares the specified object with this collection for equality.

Obeys the general contract of Collection.equals.

Specified by:

equals in interface Collection

Specified by:

equals in interface Set

Overrides:

equals in class Object

Parameters:

Specified by:

hashCode in interface Collection

Specified by:

hashCode in interface Set

Overrides:

hashCode in class Object

Returns:

the hash code value for this collection

toString
