Class MessageBodyFactory.DeclarationDistanceComparator<T>

java.lang.Object

org.glassfish.jersey.message.internal.MessageBodyFactory.DeclarationDistanceComparator<T>

Type Parameters:

T - common super-type used for computing the declaration distance and comparing instances.

All Implemented Interfaces:

Comparator<T>

Enclosing class:

MessageBodyFactory

private static class MessageBodyFactory.DeclarationDistanceComparator<T>
extends Object
implements Comparator<T>

Compares 2 instances implementing/inheriting the same super-type and returns which of the two instances has the super-type declaration closer in it's inheritance hierarchy tree.

The comparator is optimized to cache results of the previous distance declaration computations.
