Uses of ContractViolation in de.alpharogroup.evaluate.object.checkers

Methods in de.alpharogroup.evaluate.object.checkers that return types with arguments of type ContractViolation

Modifier and Type	Method and Description
static <T> Optional<ContractViolation>	ToStringCheck.consistency(T object) Checks consistency of method Object.toString() for the given objects This method calls the same name method with default iterations of 7
static <T> Optional<ContractViolation>	HashcodeCheck.consistency(T object) Checks consistency of the given object, that means according to Object.hashCode() that this method should evaluate the following contract condition: Whenever it is invoked on the same object more than once during an execution of a Java application, the hashCode method must consistently return the same integer, provided no information used in equals comparisons on the object is modified.
static <T> Optional<ContractViolation>	ToStringCheck.consistency(T object, int iterations) Checks consistency of method Object.toString() for the given objects
static <T> Optional<ContractViolation>	EqualsCheck.consistency(T object, T anotherObject) Checks the contract condition for consistency of the given objects, that means according to Object.equals(Object) that this method should evaluate the following contract condition: It is consistent: for any non-null reference values x and y, multiple invocations of x.equals(y) consistently return true or consistently return false, provided no information used in equals comparisons on the objects is modified.
static <T> Optional<ContractViolation>	EqualsCheck.consistency(T object, T anotherObject, int iterations) Checks the contract condition for consistency of the given objects, that means according to Object.equals(Object) that this method should evaluate the following contract condition: It is consistent: for any non-null reference values x and y, multiple invocations of x.equals(y) consistently return true or consistently return false, provided no information used in equals comparisons on the objects is modified.
static <T> Optional<ContractViolation>	HashcodeCheck.equality(T object, T anotherObject) Checks equality of hash code from the given objects that should be equal(if not an IllegalArgumentException will be thrown), that means according to Object.hashCode() that this method should evaluate the following contract condition: If two objects are equal according to the equals(Object) method, then calling the hashCode method on each of the two objects must produce the same integer result.

static <T> Optional<ContractViolation>	EqualsHashCodeAndToStringCheck.equalsHashcodeAndToString(T first, T second, T third, T fourth) Checks the all the contract conditions for the methods Object.equals(Object), Object.hashCode() and Object.toString().
static <T> Optional<ContractViolation>	EqualsHashCodeAndToStringCheck.equalsHashcodeEqualityAndToString(T object, T otherObject, T anotherObject) Deprecated. use instead the ToStringCheck.consistency method in combination with the HashcodeCheck.consistency, the HashcodeCheck.equality method and the EqualsCheck.reflexivityNonNullSymmetricConsistencyAndTransitivity method.
