CheckingEqualizer

class CheckingEqualizer[L](val leftSide: L)

Class used via an implicit conversion to enable two objects to be compared with === and !== with a Boolean result and an 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))
Value parameters:
leftSide

An object to convert to Equalizer, which represents the value on the left side of a === or !== invocation.

Value members

Concrete methods

def !==[R](rightSide: R)(implicit constraint: CanEqual[L, R]): Boolean

Compare two objects for inequality, returning a Boolean, using the Constraint instance passed as constraint.

Compare two objects for inequality, returning a Boolean, using the Constraint instance passed as constraint.

Value parameters:
constraint

an implicit Constraint instance that enforces a relationship between types L and R and defines a way of calculating equality for objects of type L

rightSide

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

Returns:

true if the leftSide and rightSide objects are not equal according to the passed Constraint instance.

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

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

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

Value parameters:
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.
