class Equalizer[L] extends AnyRef

Class used via an implicit conversion to enable any two objects to be compared with === and !== with a Boolean result and no enforced type constraint between two object types. For example:

assert(a === b)
assert(c !== d)

You can also check numeric values against another with a tolerance. Here are some examples:

assert(a === (2.0 +- 0.1))
assert(c !== (2.0 +- 0.1))

    Determines whether an object reference is non-null.

    literalNull

    a null value against which to compare the value passed to the constructor as leftSide for inequality

    returns

    true if the value passed to the constructor as leftSide is non-null.

  3. def !==(spread: Spread[L]): Boolean

    Permalink

    Determine whether a numeric object is outside the passed Spread, returning a Boolean.

    spread

    the Spread against which to compare the value passed to the constructor as leftSide

    returns

    true if the value passed to the constructor as leftSide is not within the Spread passed to this method.

  4. def !==(rightSide: Any)(implicit equality: Equality[L]): Boolean

    Compare two objects for inequality, returning a Boolean, using the Equality type class passed as equality.

    Compare two objects for inequality, returning a Boolean, using the Equality type class passed as equality.

    rightSide

    the object to compare for inequality with leftSide, passed to the constructor

    equality

    an implicit Equality type class that defines a way of calculating equality for objects of type L

    returns

    true if the leftSide and rightSide objects are not equal according to the passed Equality type class.
