IntPairProperty¶

[Source]

A property implementation for conveniently evaluating properties for pairs of integers of all Pony integer types at once.

The property needs to be formulated inside the method int_property:

class CommutativeMultiplicationProperty is IntPairProperty
  fun name(): String => "commutativity/mul"

  fun int_property[T: (Int & Integer[T] val)](x: T, y: T, h: PropertyHelper)? =>
    h.assert_eq[T](x * y, y * x)

trait ref IntPairProperty is
  Property1[IntPairPropertySample ref] ref

Implements¶

Property1[IntPairPropertySample ref] ref
