ReferenceCountingSet<'a>
represents a set of elements having a reference count. this means that an element is contained when it has been added at least once more than removed.
Constructors
| Constructor | Description |
new()
Signature: unit -> ReferenceCountingSet<'a>
|
|
new(initial)
Signature: initial:seq<'a> -> ReferenceCountingSet<'a>
|
|
Instance members
| Instance member | Description |
Add(v)
Signature: v:'a -> bool
|
adds an element to the ReferenceCountingSet and returns true if the element was not contained in the set before this operation. |
Clear()
Signature: unit -> unit
|
clears the entire set |
Contains(v)
Signature: v:'a -> bool
|
checks if the set contains a specific element |
Count
Signature: int
|
returns the number of (distinct) elements contained in the set. |
ExceptWith(items)
Signature: items:seq<'a> -> unit
|
Remove items in other from this set. Modifies this set. |
GetReferenceCount(v)
Signature: v:'?8257 -> int
|
gets the current reference count for the given element |
IntersectWith(other)
Signature: other:seq<'a> -> unit
|
Takes the intersection of this set with other. Modifies this set. |
IsProperSubsetOf(other)
Signature: other:seq<'a> -> bool
|
determines if the set is a proper subset of the given sequence |
IsProperSupersetOf(other)
Signature: other:seq<'a> -> bool
|
determines if the set is a proper superset of the given sequence |
IsSubsetOf(other)
Signature: other:seq<'a> -> bool
|
Sets the contents of the set to other's contents returning a list of Deltas which need to be performed in order to reproduce the transition. Runtime: O[(LookUp + AddRem) * (this.Count + other.Count)] |
IsSupersetOf(other)
Signature: other:seq<'a> -> bool
|
determines if the set is a superset of the given sequence |
Overlaps(other)
Signature: other:seq<'a> -> bool
|
determines if the set and the given sequence overlap |
Remove(v)
Signature: v:'a -> bool
|
removes an element from the ReferenceCountingSet and returns true if the element is no longer contained after the operation. |
SetEquals(other)
Signature: other:seq<'a> -> bool
|
determines if the set is equal (set) to the given sequence |
SymmetricExceptWith(other)
Signature: other:seq<'a> -> unit
|
Takes symmetric difference (XOR) with other and this set. Modifies this set. |
UnionWith(other)
Signature: other:seq<'a> -> unit
|
Take the union of this set with other. Modifies this set. |
