Constructor Detail

RestrictedCollections.RestrictedSortedSet

public RestrictedCollections.RestrictedSortedSet(java.util.SortedSet set,
                                                 java.lang.Class clz)

Constructor.

Parameters:

set - the underlying SortedSet

clz - the class of objects that may be stored in the SortedSet

Method Detail

comparator

public java.util.Comparator comparator()

Returns the comparator associated with this sorted set, or null if it uses its elements' natural ordering.

Specified by:

comparator in interface java.util.SortedSet

Returns:

the comparator associated with this sorted set, or null if it uses its elements' natural ordering

subSet

public java.util.SortedSet subSet(java.lang.Object fromElement,
                                  java.lang.Object toElement)

Returns a view of the portion of this sorted set whose elements range from fromElement, inclusive, to toElement, exclusive. (If fromElement and toElement are equal, the returned sorted set is empty.) The returned sorted set is backed by this sorted set, so changes in the returned sorted set are reflected in this sorted set, and vice-versa. The returned sorted set supports all optional set operations that this sorted set supports.

Obeys the general contract of SortedSet.subSet.

Specified by:

subSet in interface java.util.SortedSet

Parameters:

fromElement - low endpoint (inclusive) of the subSet

toElement - high endpoint (exclusive) of the subSet

Returns:

a view of the specified range within this sorted set

headSet

public java.util.SortedSet headSet(java.lang.Object toElement)

Returns a view of the portion of this sorted set whose elements are strictly less than toElement. The returned sorted set is backed by this sorted set, so changes in the returned sorted set are reflected in this sorted set, and vice-versa. The returned sorted set supports all optional set operations.

Obeys the general contract of SortedSet.headSet.

Specified by:

headSet in interface java.util.SortedSet

Parameters:

toElement - high endpoint (exclusive) of the headSet

Returns:

a view of the specified initial range of this sorted set

tailSet

public java.util.SortedSet tailSet(java.lang.Object fromElement)

Returns a view of the portion of this sorted set whose elements are greater than or equal to fromElement. The returned sorted set is backed by this sorted set, so changes in the returned sorted set are reflected in this sorted set, and vice-versa. The returned sorted set supports all optional set operations.

Obeys the general contract of SortedSet.tailSet.

Specified by:

tailSet in interface java.util.SortedSet

Parameters:

fromElement - low endpoint (inclusive) of the tailSet

Returns:

a view of the specified final range of this sorted set

first

public java.lang.Object first()

Returns the first (lowest) element currently in this sorted set.

Specified by:

first in interface java.util.SortedSet

Returns:

the first (lowest) element currently in this sorted set

Throws:

NoSuchElementException - sorted set is empty

last

public java.lang.Object last()

Returns the last (highest) element currently in this sorted set.

Specified by:

last in interface java.util.SortedSet

Returns:

the last (highest) element currently in this sorted set

Throws:

NoSuchElementException - sorted set is empty
