Class JsonComposerServlet

java.lang.Object

javax.servlet.GenericServlet

javax.servlet.http.HttpServlet

jsondiscoverer.web.AbstractJsonDiscoverer

jsondiscoverer.web.JsonComposerServlet

All Implemented Interfaces:

java.io.Serializable, javax.servlet.Servlet, javax.servlet.ServletConfig

Direct Known Subclasses:

JsonPathCalculatorServlet

@WebServlet(value="/composer")
public class JsonComposerServlet
extends AbstractJsonDiscoverer

Servlet providing access to JsonComposer

Answers to POST HTTP calls. Receives as input a set JSON documents representing several JSON-based Web APIs (see paramsPattern to know the pattern the param has to follow).

Discovers a graph representing the different APIs (as subgraphs) where nodes represents concepts/attributes and edges link concepts with their attributes. Additionally, extra edges are added to represent similar concepts and therefore potential composition links

Graphs are encoded as GEXF.
