EqualityMatcher

Type Parameters:

T - the type of objects to be compared for equality

All Known Implementing Classes:

SimpleTypeComparison, SimpleTypeIdentityComparison
```
public interface EqualityMatcher<T>
```
Interface representing objects used to perform equality matching. This is used in preference to wrapping the objects in a wrapper with its own equals() and hashCode() methods, to avoid the overhead of wrapper objects in a large data structure

- Method Detail
  - equal
```
boolean equal(T a,
              T b)
```
    Compare two objects for equality
    
    Parameters:
    
    a - one object
    
    b - another object
    
    Returns:
    
    true if the two objects are deemed equal
  - hash
```
int hash(T a)
```
    Compute a hash code for an object
    
    Parameters:
    
    a - an object
    
    Returns:
    
    a hash code, which has the property that if two objects are equal, then they must have the same hash code
