getSchemaLocation in interface JsonValidator

Returns:

the schema location

getEvaluationPath

Specified by:

getEvaluationPath in interface JsonValidator

Returns:

the evaluation path

getKeyword

public String getKeyword()

Description copied from interface: JsonValidator

The keyword of the validator.

Specified by:

getKeyword in interface JsonValidator
