Adapter classes are:

Provider node

The JsonNode abstraction wraps a concrete class from JSON/YAML library, which is called a "provider node." It is possible to interact with the API using provider nodes directly, but there is no type information at compile time, so please ensure that you are using the correct class.

Usage

Creating Validator instance

JsonNodeFactory factory = new JettisonNode.Factory();
Validator validator = new ValidatorFactory()
        .withJsonNodeFactory(factory)
        .createValidator();

Converting String to JsonNode

JsonNodeFactory factory = new JettisonNode.Factory();
JsonNode jsonNode = factory.create("{}");

Converting provider node to JsonNode

Object providerNode = new JSONTokener("{}").nextValue();
JsonNodeFactory factory = new JettisonNode.Factory();
JsonNode jsonNode = factory.wrap(providerNode);

Using Validator with provider nodes

Object providerSchemaNode = new JSONTokener("{}").nextValue();
URI schemaUri = validator.registerSchema(providerSchemaNode);

Object providerInstanceNode = new JSONTokener("true").nextValue();
Validator.Result result = validator.validate(schemaUri, providerInstanceNode);
