public class StoredSortedValueSet extends StoredValueSet implements java.util.SortedSet
In addition to the standard SortedSet methods, this class provides the following methods for stored sorted value sets only. Note that the use of these methods is not compatible with the standard Java collections interface.

StoredSortedValueSet(Database database,
EntityBinding valueEntityBinding,
boolean writeAllowed)
Creates a sorted value set entity view of a
Database . |
Modifier and Type | Method and Description |
---|---|
java.util.Comparator |
comparator()
Returns null since comparators are not supported.
|
java.lang.Object |
first()
Returns the first (lowest) element currently in this sorted set.
|
java.util.SortedSet |
headSet(java.lang.Object toValue)
Returns a view of the portion of this sorted set whose elements are
strictly less than toValue.
|
java.util.SortedSet |
headSet(java.lang.Object toValue,
boolean toInclusive)
Returns a view of the portion of this sorted set whose elements are
strictly less than toValue, optionally including toValue.
|
java.lang.Object |
last()
Returns the last (highest) element currently in this sorted set.
|
java.util.SortedSet |
subSet(java.lang.Object fromValue,
boolean fromInclusive,
java.lang.Object toValue,
boolean toInclusive)
Returns a view of the portion of this sorted set whose elements are
strictly greater than fromValue and strictly less than toValue,
optionally including fromValue and toValue.
|
java.util.SortedSet |
subSet(java.lang.Object fromValue,
java.lang.Object toValue)
Returns a view of the portion of this sorted set whose elements range
from fromValue, inclusive, to toValue, exclusive.
|
java.util.SortedSet |
tailSet(java.lang.Object fromValue)
Returns a view of the portion of this sorted set whose elements are
greater than or equal to fromValue.
|
java.util.SortedSet |
tailSet(java.lang.Object fromValue,
boolean fromInclusive)
Returns a view of the portion of this sorted set whose elements are
strictly greater than fromValue, optionally including fromValue.
