                                Record inputRecord)
                         throws java.lang.Exception

Description copied from class: JsonRequestHandler

process input record and return result object. Override this method in your handler if you do not need access to HttpExchange object, e.g. to read http header fields. Otherwise use overloaded method with HttpExchange parameter.

Overrides:

process in class JsonRequestHandler

Parameters:

method - HTTP method

requestUri - request URI.

inputRecord - input record parsed either from request body, if it has content, or from request URI parameters.

Returns:

Throws:

java.lang.Exception - any failure during processing.
