callback

public final AsyncRequestWrapper<R> callback(URI url)

Description copied from interface: AsyncRequestWrapper

The odata.callback preference MUST include the parameter url whose value is the URL of a callback endpoint to be invoked by the OData service when data is available. The syntax of the odata.callback preference is specified in [OData-ABNF].
For HTTP based callbacks, the OData service executes an HTTP GET request against the specified URL.
Services that support odata.callback SHOULD support notifying the client through HTTP.

Specified by:

callback in interface AsyncRequestWrapper<R extends ODataResponse>

Parameters:

url - callback URL

Returns:

the current AsyncRequestWrapper instance.

extendHeader

protected final void extendHeader(String headerName,
                                  String headerValue)

execute

public AsyncResponseWrapper<R> execute()

Description copied from interface: AsyncRequestWrapper

execute the request for the first time.

Specified by:

execute in interface AsyncRequestWrapper<R extends ODataResponse>

Returns:

doExecute

protected org.apache.http.HttpResponse doExecute()

checkMonitor

protected final org.apache.http.HttpResponse checkMonitor(URI location)

executeHttpRequest

protected final org.apache.http.HttpResponse executeHttpRequest(org.apache.http.client.HttpClient client,
                                                                org.apache.http.client.methods.HttpUriRequest req)
