Method Summary

protected HttpMethodBase	createCommonsHttpMethod(HttpMethod httpMethod, String uri) Create a Commons HttpMethodBase object for the given HTTP method and URI specification.
ClientHttpRequest	createRequest(URI uri, HttpMethod httpMethod) Create a new ClientHttpRequest for the specified URI and HTTP method.

Parameters:

httpClient - the HttpClient instance to use for this factory

Method Detail

setHttpClient

public void setHttpClient(HttpClient httpClient)

Set the HttpClient used by this factory.

getHttpClient

public HttpClient getHttpClient()

Return the HttpClient used by this factory.

setConnectTimeout

public void setConnectTimeout(int timeout)

createRequest

public ClientHttpRequest createRequest(URI uri,
                                       HttpMethod httpMethod)
                                throws IOException

                                                 String uri)

Create a Commons HttpMethodBase object for the given HTTP method and URI specification.

Parameters:

httpMethod - the HTTP method

uri - the URI

Returns:

the Commons HttpMethodBase object

postProcessCommonsHttpMethod

protected void postProcessCommonsHttpMethod(HttpMethodBase httpMethod)

Template method that allows for manipulating the HttpMethodBase before it is returned as part of a CommonsClientHttpRequest.

The default implementation is empty.

Parameters:

httpMethod - the Commons HTTP method object to process

destroy

public void destroy()

Shutdown hook that closes the underlying HttpConnectionManager's connection pool, if any.
