 A SchemaValidator has one method, which validates that a Schema is compatible with the other schemas provided.




What makes one Schema compatible with another is not part of the interface
contract.

public interface SchemaValidator {

  
Validate one schema against others. The order of the schemas to validate
against is chronological from most recent to oldest, if there is a natural
chronological order. This allows some validators to identify which schemas
are the most "recent" in order to validate only against the most recent
schema(s).

Params:
  • toValidate – The schema to validate
  • existing –   The schemas to validate against, in order from most recent
                  to latest if applicable
Throws:
