Examples with FilterHolder org.ballerinalang.net.http.serviceendpoint.FilterHolder used on opensource projects

Example 1 with FilterHolder

the class BallerinaHTTPConnectorListener method invokeRequestFilters.

 * relevant error message given from the filter will be returned to the user.
 *
 * @param httpCarbonMessage {@link HTTPCarbonMessage} instance
 * @param requestObject     Representation of ballerina.net.Request struct
 * @param filterCtxt        filtering criteria
