Inheritance diagram for Loyc.Collections.Set< T >:

Remarks

An immutable set.

This is the immutable version of MSet<T>. It does not allow changes to the set, but it provides operators (&, |, ^, -) for intersecting, merging, and subtracting sets, and it can be converted to a mutable MSet<T> in O(1) time. You can also add single items to the set using operators + and -.

For more information, please read the documentation of Set<T> and Impl.InternalSet<T>.

Performance warning: GetHashCode() XORs the hashcodes of all items in the set, while Equals() is a synonym for SetEquals(). Be aware that these methods are very slow for large sets.

CountMemory()

long Loyc.Collections.Set< T >.CountMemory ( int  sizeOfT )

inline

Measures the total size of all objects allocated to this collection, in bytes, including the size of this object itself; see Impl.InternalSet<T>.CountMemory.

IsSubsetOf()

bool Loyc.Collections.Set< T >.IsSubsetOf ( IEnumerable< T >  other )

inline

Returns true if all items in this set are present in the other set.

Referenced by Loyc.Collections.Set< Loyc.LLParserGenerator.AndPred >.IsProperSubsetOf(), and Loyc.Collections.Set< Loyc.LLParserGenerator.AndPred >.SetEquals().

IsSupersetOf()

bool Loyc.Collections.Set< T >.IsSupersetOf ( IEnumerable< T >  other )

inline

Returns true if all items in the other set are present in this set.

Referenced by Loyc.Collections.Set< Loyc.LLParserGenerator.AndPred >.IsProperSupersetOf().

Overlaps()

bool Loyc.Collections.Set< T >.Overlaps ( IEnumerable< T >  other )

inline

Returns true if this set contains at least one item from 'other'.

Where()

Set<T> Loyc.Collections.Set< T >.Where ( Predicate< T >  match )

inline

Returns a new set that contains only items that match the specified predicate (i.e. for which the predicate returns true).
