Constructor Detail

### JsonpRequest

    JsonpRequest(AsyncCallback<T> callback,
                 int timeout,
                 boolean expectInteger,
                 java.lang.String callbackParam,
                 java.lang.String failureCallbackParam)

  Create a new JSONP request.

  Parameters:
    `callback` - The callback instance to notify when the response comes back
    `timeout` - Time in ms after which a `TimeoutException` will be thrown
    `expectInteger` - Should be true if T is `Integer`, false otherwise
    `callbackParam` - Name of the url param of the callback function name
    `failureCallbackParam` - Name of the url param containing the failure callback function name, or null for no failure callback

### JsonpRequest

    JsonpRequest(AsyncCallback<T> callback,
                 int timeout,
                 boolean expectInteger,
                 java.lang.String callbackParam,
                 java.lang.String failureCallbackParam,
                 java.lang.String id)

  Create a new JSONP request with a hardcoded id. This could be used to manually control which resources are considered duplicates (by giving them identical ids). Could also be used if the callback name needs to be completely user controlled (since the id is part of the callback name).

  Parameters:
    `callback` - The callback instance to notify when the response comes back
    `timeout` - Time in ms after which a `TimeoutException` will be thrown
    `expectInteger` - Should be true if T is `Integer`, false otherwise
    `callbackParam` - Name of the url param of the callback function name
    `failureCallbackParam` - Name of the url param containing the failure callback function name, or null for no failure callback
    `id` - unique id for the resource that is being fetched

Method Detail

### cancel

    public void cancel()

  Cancels a pending request. Note that if you are using preset ID's, this will not work, since there is no way of knowing if there are other requests pending (or have already returned) for the same data.

### getCallback

    public AsyncCallback<T> getCallback()

### getTimeout

    public int getTimeout()

### toString

    public java.lang.String toString()

  Overrides:
    `toString` in class `java.lang.Object`

### getCallbackId

    java.lang.String getCallbackId()

### send

    void send(java.lang.String baseUri)

  Sends a request using the JSONP mechanism.

  Parameters:
    `baseUri` - To be sent to the server.
