Method Detail

get

public java.util.Comparator<?> get(java.lang.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 all the superclasses of clazz 3. We check if there is a registered comparator for all the interfaces if clazz

Parameters:

clazz - the class for which to find a comparator

Returns:

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

put

public <T> void put(java.lang.Class<T> clazz,
                    java.util.Comparator<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

hashCode

public int hashCode()

Overrides:

hashCode in class java.lang.Object

equals

public boolean equals(java.lang.Object obj)

Overrides:

equals in class java.lang.Object

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object
