AbstractSortedSet

Object Hierarchy:

public abstract class AbstractSortedSet<G> : AbstractSet<G>, SortedSet<G>

Skeletal implementation of the SortedSet interface.

Contains common code shared by all set implementations.

public virtual SortedSet<G> read_only_view { owned get; }
The read-only view of this set.

public abstract G ceil (G element)
Returns the element which is higher or equal then the specified element.
public abstract G first ()
Returns the first element of the sorted set. Set must not be empty.
public abstract G floor (G element)
Returns the element which is lower or equal then the specified element.
public abstract SortedSet<G> head_set (G before)
Returns the sub-set of this sorted set containing elements strictly lower than the specified element.
public abstract G higher (G element)
Returns the element which is strictly higher than the specified element.
public abstract Iterator<G>? iterator_at (G element)
Returns a BidirIterator initially pointed at the specified element.
public abstract G last ()
Returns the last element of the sorted set. Set must not be empty.
public abstract G lower (G element)
Returns the element which is strictly lower than the specified element.
public abstract SortedSet<G> sub_set (G from, G to)
Returns the right-open sub-set of this sorted set, thus containing elements equal or higher than the specified from element, and stricly lower than the specified to element.
public abstract SortedSet<G> tail_set (G after)
Returns the sub-set of this sorted set containing elements equal or higher than the specified element.
