checkEqualsAndHashCode

public static <T> void checkEqualsAndHashCode(T x,
                                              T y,
                                              boolean equal)

Generic checks of Object.equals(Object) and Object.hashCode().

Type Parameters:

T - the generic type of the object to test.

Parameters:

x - the first instance of the object to test.

y - the second instance of the object to test.

equal - - true if x.equals(y) is expected, false otherwise.

checkEquals

public static <T> void checkEquals(T x,
                                   T y,
                                   boolean equal)

Generic checks of Object.equals(Object).

Type Parameters:

T - the generic type of the object to test.

Parameters:

x - the first instance of the object to test.

y - the second instance of the object to test.

equal - - true if x.equals(y) is expected, false otherwise.

checkHashCode

public static <T> void checkHashCode(T x,
                                     T y)

Generic checks of Object.hashCode().

Type Parameters:

T - the generic type of the object to test.

Parameters:

x - the first instance of the object to test.

y - the second instance of the object to test.
