Class Call

  • public class Call
extends Object
    A call is a request that has been prepared for execution. A call can be canceled. As this object represents a single request/response pair (stream), it cannot be executed twice.

    • Method Detail

      • execute

        public Response execute()
                 throws IOException
        Invokes the request immediately, and blocks until the response can be processed or is in error.

        The caller may read the response body with the response's Response.body method. To facilitate connection recycling, callers should always close the response body.

        Note that transport-layer success (receiving a HTTP response code, headers and body) does not necessarily indicate application-layer success: response may still indicate an unhappy HTTP response code like 404 or 500.

        Throws:
        IOException - if the request could not be executed due to cancellation, a connectivity problem or timeout. Because networks can fail during an exchange, it is possible that the remote server accepted the request before the failure.
        IllegalStateException - when the call has already been executed.

      • enqueue

        public void enqueue​(Callback responseCallback)
        Schedules the request to be executed at some point in the future.

        The dispatcher defines when the request will run: usually immediately unless there are several other requests currently being executed.

        This client will later call back responseCallback with either an HTTP response or a failure exception. If you cancel() a request before it completes the callback will not be invoked.

        Throws:
        IllegalStateException - when the call has already been executed.

      • cancel

        public void cancel()
        Cancels the request, if possible. Requests that are already complete cannot be canceled.

      • isCanceled

        public boolean isCanceled()
