EqualityComparator (ANTLR 4 Runtime 4.13.1 API)

All Known Implementing Classes:

AbstractEqualityComparator, ATNConfigSet.ConfigEqualityComparator, ObjectEqualityComparator
```
public interface EqualityComparator<T>
```
This interface provides an abstract concept of object equality independent of Object.equals(java.lang.Object) (object equality) and the == operator (reference equality). It can be used to provide algorithm-specific unordered comparisons without requiring changes to the object itself.
