public Interface EqualityComparator<T>

Known Direct Implementers: org.antlr.v4.runtime.misc.AbstractEqualityComparator

This interface provides an abstract concept of object equality independent of Object#equals (object equality) and the == operator (reference equality). It can be used to provide algorithm-specific unordered comparisons without requiring changes to the object itself.
