Interface HashingStrategy<T>

All Superinterfaces:

Serializable

All Known Implementing Classes:

IdentityHashingStrategy
```
public interface HashingStrategy<T>
extends Serializable
```
Interface to support pluggable hashing strategies in maps and sets. Implementers can use this interface to make the trove hashing algorithms use object values, values provided by the java runtime, or a custom strategy when computing hashcodes.

  - computeHashCode
```
int computeHashCode(T object)
```
    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.
    
    Parameters:
    
    object - for which the hashcode is to be computed
    
    Returns:
    
    the hashCode
  - equals
```
boolean equals(T o1,
               T o2)
```
    Compares o1 and o2 for equality. Strategy implementers may use the objects' own equals() methods, compare object references, or implement some custom scheme.
    
    Parameters:
    
    o1 - an Object value
    
    o2 - an Object value
    
    Returns:
    
    true if the objects are equal according to this strategy.
