Hash<T> class abstract

A type class used to represent a hashing scheme for objects of a given type.

For any two instances x and y that are considered equivalent under the equivalence relation defined by this object, hash(x) should equal hash(y).

Properties

hashCode → int

Methods

and(Eq<T> eq) → Eq<T>

Return an Eq that gives the result of and of eq1 and eq2.

inherited

contramap<A>(T map(A)) → Eq<A>

Return an Eq instance based on a parameter of type T extracted from a class A.

inherited

eqv(T x, T y) → bool

Returns true if x and y are equivalent, false otherwise.

inherited

hash(T x) → int

Returns the hash code of the given object under this hashing scheme.

override

neqv(T x, T y) → bool

Returns false if x and y are equivalent, true otherwise.

inherited

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

or(Eq<T> eq) → Eq<T>

Return an Eq that gives the result of or of this Eq and eq.

inherited

toString() → String

A string representation of this object.

inherited

xor(Eq<T> eq) → Eq<T>

Return an Eq that gives the result of xor of this Eq and eq.

inherited

Operators

operator ==(Object other) → bool

The equality operator.

Static Methods

fromUniversalHashCode<A>() → Hash<A>

Constructs a Hash instance by using the universal hashCode function and the universal equality relation.
