package org.apache.commons.collections4;

 * An equation function, which determines equality between objects of type T.
 * <p>
 * It is the functional sibling of {@link java.util.Comparator}; {@link Equator} is to
 * {@link Object} as {@link java.util.Comparator} is to {@link java.lang.Comparable}.
 * </p>
 * @param <T> the types of object this {@link Equator} can evaluate.
 * @since 4.0
public interface Equator<T> {
     * Evaluates the two arguments for their equality.
     * @param o1 the first object to be equated.
     * @param o2 the second object to be equated.
     * @return whether the two objects are equal.
    boolean equate(T o1, T o2);

     * Calculates the hash for the object, based on the method of equality used in the equate
     * method. This is used for classes that delegate their {@link Object#equals(Object) equals(Object)} method to an
     * Equator (and so must also delegate their {@link Object#hashCode() hashCode()} method), or for implementations
     * of {@link} that use an Equator for the key objects.
     * @param o the object to calculate the hash for.
     * @return the hash of the object.
    int hash(T o);
