                    java.lang.String errorMessage)

Method Detail

getCategory

public FacebookRequestError.Category getCategory()

Returns the category in which the error belongs. Applications can use the category to determine how best to handle the errors (e.g. exponential backoff for retries if being throttled).

Returns:

the category in which the error belong

getRequestStatusCode

public int getRequestStatusCode()

Returns the HTTP status code for this particular request.

Returns:

the HTTP status code for the request

getErrorCode

public int getErrorCode()

Returns the error code returned from Facebook.

Returns:

the error code returned from Facebook

getSubErrorCode

public int getSubErrorCode()

Returns the sub-error code returned from Facebook.

Returns:

the sub-error code returned from Facebook

getErrorType

public java.lang.String getErrorType()

Returns the type of error as a raw string. This is generally less useful than using the getCategory() method, but can provide further details on the error.

Returns:

the type of error as a raw string

getErrorMessage

public java.lang.String getErrorMessage()

Returns the error message returned from Facebook.

Returns:

the error message returned from Facebook

getErrorRecoveryMessage

public java.lang.String getErrorRecoveryMessage()

Returns the message that can be displayed to the user before attempting error recovery.

Returns:

the message that can be displayed to the user before attempting error recovery

getErrorUserMessage

public java.lang.String getErrorUserMessage()

Returns a message suitable for display to the user, describing a user action necessary to enable Facebook functionality. Not all Facebook errors yield a message suitable for user display; however in all cases where shouldNotifyUser() returns true, this method returns a non-null message suitable for display.

Returns:

the error message returned from Facebook

getErrorUserTitle

public java.lang.String getErrorUserTitle()

Returns a short summary of the error suitable for display to the user. Not all Facebook errors yield a title/message suitable for user display; however in all cases where getErrorUserTitle() returns valid String - user should be notified.

Returns:

the error message returned from Facebook

getRequestResultBody

public org.json.JSONObject getRequestResultBody()

Returns the body portion of the response corresponding to the request from Facebook.

Returns:

the body of the response for the request

getRequestResult

public org.json.JSONObject getRequestResult()

Returns the full JSON response for the corresponding request. In a non-batch request, this would be the raw response in the form of a JSON object. In a batch request, this result will contain the body of the response as well as the HTTP headers that pertain to the specific request (in the form of a "headers" JSONArray).

Returns:

the full JSON response for the request

getBatchRequestResult

public java.lang.Object getBatchRequestResult()

Returns the full JSON response for the batch request. If the request was not a batch request, then the result from this method is the same as getRequestResult(). In case of a batch request, the result will be a JSONArray where the elements correspond to the requests in the batch. Callers should check the return type against either JSONObject or JSONArray and cast accordingly.

Returns:

the full JSON response for the batch

getConnection

public java.net.HttpURLConnection getConnection()

Returns the HTTP connection that was used to make the request.
