Usage

From source file:org.opennms.ng.services.eventconfig.EventExpander.java

/**
 * <p>afterPropertiesSet</p>

From source file:org.biopax.validator.ws.ValidatorController.java

/**
 * JSP pages and RESTful web services controller, the main one that checks BioPAX data.
 * All parameter names are important, i.e., these are part of public API (for clients)
 * //from   w  w w .  j  a  v a2s  . c  o  m
 * Framework's built-in parameters:
 * @param request the web request object (may contain multi-part data, i.e., multiple files uploaded)
 * @param response 
 * @param mvcModel Spring MVC Model
 * @param writer HTTP response writer
 * 
 * BioPAX Validator/Normalizer query parameters:
 * @param url
 * @param retDesired
 * @param autofix
 * @param filter
 * @param maxErrors
 * @param profile
 * @param normalizer binds to three boolean options: normalizer.fixDisplayName, normalizer.inferPropertyOrganism, normalizer.inferPropertyDataSource
 * @return
 * @throws IOException
