Class TypeComparators

java.lang.Object
org.assertj.core.internal.TypeComparators
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.

    • 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.
