Method Details

doGet

protected void doGet(javax.servlet.http.HttpServletRequest request,
 javax.servlet.http.HttpServletResponse response)
              throws IOException

Handles an HTTP GET request from a client by writing the definition of the word specified in the "word" HTTP parameter to the HTTP response. If the "word" parameter is not specified, all of the entries in the dictionary are written to the HTTP response.

Overrides:

doGet in class javax.servlet.http.HttpServlet

Throws:

IOException

doPost

protected void doPost(javax.servlet.http.HttpServletRequest request,
 javax.servlet.http.HttpServletResponse response)
               throws IOException

Handles an HTTP POST request by storing the dictionary entry for the "word" and "definition" request parameters. It writes the dictionary entry to the HTTP response.

Overrides:

doPost in class javax.servlet.http.HttpServlet

Throws:

IOException

doDelete

protected void doDelete(javax.servlet.http.HttpServletRequest request,
 javax.servlet.http.HttpServletResponse response)
                 throws IOException

Handles an HTTP DELETE request by removing all dictionary entries. This behavior is exposed for testing purposes only. It's probably not something that you'd want a real application to expose.

Overrides:

doDelete in class javax.servlet.http.HttpServlet

Throws:

IOException

getDefinition

String getDefinition(String word)
