case class Prop[T, S](label: String, actual: Property[T], expected: Property[S], constraint: (T, S) => Result, decorator: Decorator) extends Executable, DecoratedProperty[Prop[T, S]]

The Prop class is a named property which holds:

  • an actual value
  • an expected value
  • a constraint to check if the actual value conforms to the expected one

This property can be executed and can be inserted in a Form.

A Prop is meant to be declared as "bound" to an actual value:

val customerName = Prop("Customer name", person.name)

[the actual value is not evaluated until the Prop is executed]

Then it can be associated an expected value with the apply method (usually in a Form declaration):

customerName("Bill")

The actual and the expected values can have different types and the constraint which is applied to them can be anything returning a result.

However the Prop companion object provides a method to create a Property with a constraint using a beEqualTo matcher:

Prop("Name", "Eric")("Eric") must_== Success("'Eric' is equal to 'Eric'")

Attributes

override def equals(other: Any): Boolean

Compares the receiver object (this) with the argument object (that) for equivalence.

Compares the receiver object (this) with the argument object (that) for equivalence.

Any implementation of this method should be an equivalence relation:

  • It is reflexive: for any instance x of type Any, x.equals(x) should return true.
  • It is symmetric: for any instances x and y of type Any, x.equals(y) should return true if and only if y.equals(x) returns true.
  • It is transitive: for any instances x, y, and z of type Any if x.equals(y) returns true and y.equals(z) returns true, then x.equals(z) should return true.

If you override this method, you should verify that your implementation remains an equivalence relation. Additionally, when overriding this method it is usually necessary to override hashCode to ensure that objects which are "equal" (o1.equals(o2) returns true) hash to the same scala.Int. (o1.hashCode.equals(o2.hashCode)).

Value parameters

that

the object to compare against this object for equality.

Attributes

Returns

true if the receiver object is equivalent to the argument; false otherwise.

Attributes

override def hashCode: Int

Calculate a hash code value for the object.

Calculate a hash code value for the object.

The default hashing algorithm is platform dependent.

Note that it is allowed for two objects to have identical hash codes (o1.hashCode.equals(o2.hashCode)) yet not be equal (o1.equals(o2) returns false). A degenerate implementation could always return 0. However, it is required that if two objects are equal (o1.equals(o2) returns true) that they have identical hash codes (o1.hashCode.equals(o2.hashCode)). Therefore, when overriding this method, be sure to verify that the behavior is consistent with the equals method.

Attributes

Returns

the hash code value for this object.
