Class NullDigester

java.lang.Object

com.github.fge.jsonschema.keyword.digest.AbstractDigester

com.github.fge.jsonschema.keyword.digest.helpers.NullDigester

All Implemented Interfaces:

Digester

public final class NullDigester
extends AbstractDigester

A digester returning a NullNode for any input

This is actually useful for keywords like anyOf, allOf and oneOf, which only roles are to validate subschemas: they do not need a digested form at all, they just have to peek at the schema.

A net result of all keywords using this digester is that only one instance will ever be built.
