public class TypeComparators
extends Object

An internal holder of the comparators for type. It is used to store comparators for registered classes. When looking for a Comparator for a given class the holder returns the most relevant comparator.

public static TypeComparators defaultTypeComparators()

get

public Comparator<?> get(Class<?> clazz)

This method returns the most relevant comparator for the given class. The most relevant comparator is the comparator which is registered for the class that is closest in the inheritance chain of the given clazz. The order of checks is the following: 1. If there is a registered comparator for clazz then this one is used 2. We check if there is a registered comparator for a superclass of clazz 3. We check if there is a registered comparator for an interface of clazz

Parameters:

clazz - the class for which to find a comparator

Returns:

the most relevant comparator, or null if no comparator could be found

hasComparatorForType

public boolean hasComparatorForType(Class<?> type)

put

public <T> void put(Class<T> clazz,
                    Comparator<? super T> comparator)

Puts the comparator for the given clazz.

Type Parameters:

T - the type of the objects for the comparator

Parameters:

clazz - the class for the comparator

comparator - the comparator it self

isEmpty

public boolean isEmpty()

Returns:

true is there are registered comparators, false otherwise

clear

public void clear()

Removes all registered comparators.

comparatorByTypes

public Stream<Map.Entry<Class<?>,Comparator<?>>> comparatorByTypes()

hashCode

public int hashCode()

Overrides:

hashCode in class Object

equals

public boolean equals(Object obj)

Overrides:

equals in class Object

toString

public String toString()

Overrides:

toString in class Object

formatRegisteredComparator
