boost::asio::io_service & | io_service () |
Get the io_service associated with the object. |
typedef Protocol boost::asio::basic_resolver< Protocol, Service >::protocol_type |
The protocol type.
typedef Protocol::endpoint boost::asio::basic_resolver< Protocol, Service >::endpoint_type |
The endpoint type.
typedef Protocol::resolver_query boost::asio::basic_resolver< Protocol, Service >::query |
The query type.
typedef Protocol::resolver_iterator boost::asio::basic_resolver< Protocol, Service >::iterator |
The iterator type.
typedef boost::asio::error boost::asio::basic_resolver< Protocol, Service >::error_type |
The type used for reporting errors.
typedef Service boost::asio::basic_io_object< Service >::service_type [inherited] |

boost::asio::basic_resolver< Protocol, Service >::basic_resolver | ( | boost::asio::io_service & | io_service | ) | [explicit] |
Constructor.
This constructor creates a basic_resolver.
io_service | The io_service object that the resolver will use to dispatch handlers for any asynchronous operations performed on the timer. |
void boost::asio::basic_resolver< Protocol, Service >::cancel | ( | ) |
Cancel any asynchronous operations that are waiting on the resolver.
This function forces the completion of any pending asynchronous operations on the host resolver. The handler for each cancelled operation will be invoked with the boost::asio::error::operation_aborted error code.
iterator boost::asio::basic_resolver< Protocol, Service >::resolve | ( | const query & | q | ) |
Resolve a query to a list of entries.
This function is used to resolve a query into a list of endpoint entries.
q | A query object that determines what endpoints will be returned. |
boost::asio::error | Thrown on failure. |
A successful call to this function is guaranteed to return at least one entry.
iterator boost::asio::basic_resolver< Protocol, Service >::resolve | ( | const query & | q, | |
Error_Handler | error_handler | |||
) |
Resolve a query to a list of entries.
This function is used to resolve a query into a list of endpoint entries.
q | A query object that determines what endpoints will be returned. |
error_handler | A handler to be called when the operation completes, to indicate whether or not an error has occurred. Copies will be made of the handler as required. The function signature of the handler must be: void error_handler( const boost::asio::error& error // Result of operation. ); |
A successful call to this function is guaranteed to return at least one entry.
void boost::asio::basic_resolver< Protocol, Service >::async_resolve | ( | const query & | q, | |
Handler | handler | |||
) |
Asynchronously resolve a query to a list of entries.
This function is used to asynchronously resolve a query into a list of endpoint entries.
q | A query object that determines what endpoints will be returned. | |
handler | The handler to be called when the resolve operation completes. Copies will be made of the handler as required. The function signature of the handler must be: void handler( const boost::asio::error& error, // Result of operation. resolver::iterator iterator // Forward-only iterator that can be used to // traverse the list of endpoint entries. ); |
A successful resolve operation is guaranteed to pass at least one entry to the handler.
iterator boost::asio::basic_resolver< Protocol, Service >::resolve | ( | const endpoint_type & | e | ) |
Resolve an endpoint to a list of entries.
This function is used to resolve an endpoint into a list of endpoint entries.
e | An endpoint object that determines what endpoints will be returned. |
boost::asio::error | Thrown on failure. |
A successful call to this function is guaranteed to return at least one entry.
iterator boost::asio::basic_resolver< Protocol, Service >::resolve | ( | const endpoint_type & | e, | |
Error_Handler | error_handler | |||
) |
Resolve an endpoint to a list of entries.
This function is used to resolve an endpoint into a list of endpoint entries.
e | An endpoint object that determines what endpoints will be returned. |
error_handler | A handler to be called when the operation completes, to indicate whether or not an error has occurred. Copies will be made of the handler as required. The function signature of the handler must be: void error_handler( const boost::asio::error& error // Result of operation. ); |
A successful call to this function is guaranteed to return at least one entry.
void boost::asio::basic_resolver< Protocol, Service >::async_resolve | ( | const endpoint_type & | e, | |
Handler | handler | |||
) |
Asynchronously resolve an endpoint to a list of entries.
This function is used to asynchronously resolve an endpoint into a list of endpoint entries.
e | An endpoint object that determines what endpoints will be returned. | |
handler | The handler to be called when the resolve operation completes. Copies will be made of the handler as required. The function signature of the handler must be: void handler( const boost::asio::error& error, // Result of operation. resolver::iterator iterator // Forward-only iterator that can be used to // traverse the list of endpoint entries. ); |
A successful resolve operation is guaranteed to pass at least one entry to the handler.
boost::asio::io_service& boost::asio::basic_io_object< Service >::io_service | ( | ) | [inherited] |
Get the io_service associated with the object.
This function may be used to obtain the io_service object that the I/O object uses to dispatch handlers for asynchronous operations.
