Constructor Detail

IdentityEquivalence

public IdentityEquivalence()

Deprecated.

Method Detail

hashCode

public int hashCode(Object obj)

Deprecated.

Description copied from interface: Equivalence

Returns a hash code value for the object passed. As an example, implementors can provide an alternative implementation for the hash code calculation for arrays. So, instead of relying on Object.hashCode(), call Object.hashCode().

Specified by:

hashCode in interface Equivalence<T>

Parameters:

obj - instance to calculate hash code for

Returns:

a hash code value for the object passed as parameter

equals

public boolean equals(T obj,
                      Object otherObj)

Deprecated.

Description copied from interface: Equivalence

Indicates whether the objects passed are "equal to" each other. As an example, implementors can provide an alternative implementation for the equals for arrays. So, instead of relying on Object.equals(Object)}, call Arrays.equals(Object[], Object[]).

Specified by:

equals in interface Equivalence<T>

Parameters:

obj - to be compared with second parameter

otherObj - to be compared with first parameter

Returns:

true if both objects are the same; false otherwise

toString

public String toString(Object obj)

Deprecated.

Description copied from interface: Equivalence

Returns a string representation of the given object.

Specified by:

toString in interface Equivalence<T>

Parameters:

obj - whose string representation is to be returned

Returns:

a string representation of the passed object

isComparable

public boolean isComparable(Object obj)

Deprecated.

Description copied from interface: Equivalence

Returns whether the given object is comparable. In other words, if given an instance of the object, a sensible comparison can be computed using Equivalence.compare(Object, Object) method.

Specified by:

isComparable in interface Equivalence<T>

Parameters:

obj - instance to check if it's comparable

Returns:

true if the object is comparable; false otherwise

compare

public int compare(T obj,
                   T otherObj)

Deprecated.

Description copied from interface: Equivalence

Compares the two given objects for order. Returns a negative integer, zero, or a positive integer as the first object is less than, equal to, or greater than the second object.

Specified by:

compare in interface Equivalence<T>

Parameters:

obj - first object to be compared

otherObj - second object to be compared

Returns:

a negative integer, zero, or a positive integer as the first object is less than, equal to, or greater than the second object
