Equivalence

All Known Implementing Classes:

Deprecated.
```
@Deprecated
public interface Equivalence<T>
extends java.io.Serializable
```
An interface that allows custom implementations for objects that are comparable based on equality, hash code calculations, or according to Comparable rules, but where the behaviour provided by the JDK, or external libraries, cannot be modified, for example: arrays. The interface is marked to be Serializable because multiple collection extensions within the Infinispan code base contain references to them, and since these are potentially Serializable, they might be persisted somehow.

All Methods Instance Methods Abstract Methods Deprecated Methods
Modifier and Type	Method and Description
`int`	`compare(T obj, T otherObj)` Deprecated. Compares the two given objects for order.
`boolean`	`equals(T obj, java.lang.Object otherObj)` Deprecated. Indicates whether the objects passed are "equal to" each other.
`int`	`hashCode(java.lang.Object obj)` Deprecated. Returns a hash code value for the object passed.
`boolean`	`isComparable(java.lang.Object obj)` Deprecated. Returns whether the given object is comparable.
`java.lang.String`	`toString(java.lang.Object obj)` Deprecated. Returns a string representation of the given object.

- Method Detail
  - hashCode
```
int hashCode(java.lang.Object obj)
```
    Deprecated.
    
    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().
    
    Parameters:
    
    obj - instance to calculate hash code for
    
    Returns:
    
    a hash code value for the object passed as parameter
  - equals
```
boolean equals(T obj,
               java.lang.Object otherObj)
```
    Deprecated.
    
    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[]).
    
    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
```
java.lang.String toString(java.lang.Object obj)
```
    Deprecated.
    
    Returns a string representation of the given object.
    
    Parameters:
    
    obj - whose string representation is to be returned
    
    Returns:
    
    a string representation of the passed object
  - isComparable
```
boolean isComparable(java.lang.Object obj)
```
    Deprecated.
    
    Returns whether the given object is comparable. In other words, if given an instance of the object, a sensible comparison can be computed using compare(Object, Object) method.
    
    Parameters:
    
    obj - instance to check if it's comparable
    
    Returns:
    
    true if the object is comparable; false otherwise
  - compare
```
int compare(T obj,
            T otherObj)
```
    Deprecated.
    
    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.
    
    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
