Class JsonSchema

java.lang.Object

com.networknt.schema.BaseJsonValidator

com.networknt.schema.JsonSchema

All Implemented Interfaces:

JsonValidator

public class JsonSchema
extends BaseJsonValidator

This is the core of json constraint implementation. It parses json constraint file and generates JsonValidators. The class is thread safe, once it is constructed, it can be used to validate multiple json data concurrently.
