java.lang.Object

org.eel.kitchen.jsonschema.ref.JsonFragment

All Implemented Interfaces:

Comparable<JsonFragment>

Direct Known Subclasses:

JsonPointer

public abstract class JsonFragment
extends Object
implements Comparable<JsonFragment>

Abstract class for fragment resolution

In a JSON Reference, a fragment can only be a JSON Pointer. All other fragments are illegal.

The only possibility for a non JSON Pointer fragment to appear is when inline addressing mode is used.
