Method Detail

equalByToString

public static boolean equalByToString(Object reference,
                      Object other)

This method returns true if the toString() methods on both objects return matching strings AND both objects are the exact same runtime type.

Returns true immediately if reference == other (ie they are the same object).

Returns false immediately if other==null or is a different runtime type than reference.

If neither one is null, and both are the exact same runtime type, then compare the toString() methods

Parameters:

reference - The object other is being compared to.

other - The object being examined for equality with reference.

Throws:

NullPointerException - If reference is null or reference.toString() returns null

equalByComparison

public static <T extends Comparable<? super T>> boolean equalByComparison(T reference,
                                                          Object object)

Return true if reference and object are not null, the exact same runtime type, and reference.compareTo(object) == 0

Throws:

NullPointerException - If reference is null

notEqual

public static boolean notEqual(Object reference,
               Object other)

Return true if reference is definitely not equal to other.

If other is null OR a different runtime type than reference, return true

Parameters:

reference - The object other is being compared to.

other - The object being examined for equality with reference.

Throws:

NullPointerException - If reference is null

equal

public static <T extends Equatable> boolean equal(T reference,
                                  Object other)

equalsByToString

@Deprecated
public static boolean equalsByToString(Object reference,
                                  Object other)

Deprecated. Use equalByToString() instead
