All Implemented Interfaces:

HashingStrategy<K>, Serializable

public class IdentityHashingStrategy<K>
extends Object
implements HashingStrategy<K>
```

  - computeHashCode
```
public int computeHashCode(K object)
```
    Description copied from interface: HashingStrategy
    
    Computes a hash code for the specified object. Implementers can use the object's own hashCode method, the Java runtime's identityHashCode, or a custom scheme.
    
    Specified by:
    
    computeHashCode in interface HashingStrategy<K>
    
    Parameters:
    
    object - for which the hashcode is to be computed
    
    Returns:
    
    the hashCode
  - equals
```
public boolean equals(K o1,
                      K o2)
```
    Description copied from interface: HashingStrategy
    
    Compares o1 and o2 for equality. Strategy implementers may use the objects' own equals() methods, compare object references, or implement some custom scheme.
    
    Specified by:
    
    equals in interface HashingStrategy<K>
    
    Parameters:
    
    o1 - an Object value
    
    o2 - an Object value
    
    Returns:
    
    true if the objects are equal according to this strategy.
