- abstract def +=(entry: E)(implicit tx: T): SkipList.this.type
- abstract def -=(key: A)(implicit tx: T): SkipList.this.type
- abstract def ceil(key: A)(implicit tx: T): Option[E]
Finds the entry with the smallest key which is greater than or equal to the search key.
Finds the entry with the smallest key which is greater than or equal to the search key.
- key
the search key
- returns
the found entry, or
Noneif there is no key greater than or equal to the search key (e.g. the list is empty)
- abstract def clear()(implicit tx: T): Unit
- abstract def contains(key: A)(implicit tx: T): Boolean
Searches for the Branch of a given key.
Searches for the Branch of a given key.
- key
the key to search for
- returns
trueif the key is in the list,falseotherwise

- abstract def firstKey(implicit tx: T): A
- abstract def floor(key: A)(implicit tx: T): Option[E]
Finds the entry with the largest key which is smaller than or equal to the search key.
Finds the entry with the largest key which is smaller than or equal to the search key.
- key
the search key
- returns
the found entry, or
Noneif there is no key smaller than or equal to the search key (e.g. the list is empty)
- abstract def head(implicit tx: T): E
Returns the first element.
Returns the first element. Throws an exception if the list is empty.
- abstract def headOption(implicit tx: T): Option[E]
Returns the first element, or
Noneif the list is empty. - abstract def height(implicit tx: T): Int
The number of levels in the skip list.
- abstract def id: Ident[T]
- Definition Classes
- Identified
- abstract def isEmpty(implicit tx: T): Boolean
- abstract def isomorphicQuery(compare: (A) => Int)(implicit tx: T): (E, Int)
Finds the nearest item equal or greater than an unknown item from an isomorphic set.
Finds the nearest item equal or greater than an unknown item from an isomorphic set. The isomorphism is represented by a comparison function which guides the binary search.
- compare
a function that guides the search. should return -1 if the argument is smaller than the search key, 0 if both are equivalent, or 1 if the argument is greater than the search key. E.g., using some mapping, the function could look like
mapping.apply(_).compare(queryKey)- returns
the nearest item, or the maximum item
- abstract def iterator(implicit tx: T): Iterator[E]
- abstract def keyFormat: TFormat[T, A]
- abstract def last(implicit tx: T): E
Returns the last element.
Returns the last element. Throws an exception if the list is empty.
- abstract def lastKey(implicit tx: T): A
- abstract def lastOption(implicit tx: T): Option[E]
Returns the last element, or
Noneif the list is empty. - abstract def maxGap: Int
The maximum gap within elements of each skip level.
- abstract def minGap: Int
The minimum gap within elements of each skip level.
- abstract def nonEmpty(implicit tx: T): Boolean
- implicit abstract def ordering: TOrdering[T, A]
The ordering used for the keys of this list.
- abstract def size(implicit tx: T): Int
Reports the number of keys in the skip list (size of the bottom level).
Reports the number of keys in the skip list (size of the bottom level). This operation may take up to O(n) time, depending on the implementation.
