Member Function Documentation

void connect	(	AsyncDNSHandler *	adh,
		const std::string &	host,
		const LogSink &	logInstance,
		void *	context
	)

This is a convenience function which uses resolve() to get a list of hosts and connects to one of them.

Parameters

adh	The result handler.
host	The host to resolve SRV records for.
logInstance	A LogSink to use for logging.
context	User-supplied context information.

Definition at line 173 of file asyncdns.cpp.

void connect	(	AsyncDNSHandler *	adh,
		const std::string &	host,
		int	port,
		const LogSink &	logInstance,
		void *	context
	)

This is a convenience function which connects to the given host and port. No SRV records are resolved. Use this function for special setups.

Parameters

adh	The result handler.
host	The host/IP address to connect to.
port	A custom port to connect to.
logInstance	A LogSink to use for logging.
context	User-supplied context information.

Definition at line 188 of file asyncdns.cpp.

void handleAsyncConnectResult ( int  fd, void *  context  )

protectedvirtual

Parameters

fd	A file descriptor for the established connection.
context	User-defined context information.

Implements AsyncDNSHandler.

Definition at line 225 of file asyncdns.cpp.

void handleAsyncResolveResult ( const DNS::HostMap &  hosts, void *  context  )

protectedvirtual

Parameters

hosts	A list of weighted hostname/port pairs from SRV records, or A records if no SRV records where found.
context	User-defined context information.

Implements AsyncDNSHandler.

Definition at line 203 of file asyncdns.cpp.

void resolve	(	AsyncDNSHandler *	adh,
		const std::string &	service,
		const std::string &	proto,
		const std::string &	domain,
		const LogSink &	logInstance,
		void *	context
	)

This function asynchronously resolves a service/protocol/domain tuple.

Parameters

adh	The result handler.
service	The SRV service type.
proto	The SRV protocol.
domain	The domain to search for SRV records.
logInstance	A LogSink to use for logging.
context	User-supplied context information.

Definition at line 158 of file asyncdns.cpp.

void resolve ( AsyncDNSHandler *  adh, const std::string &  domain, const LogSink &  logInstance, void *  context  )

inline

This is a convenience funtion which uses resolve() to resolve SRV records asynchronously for a given domain, using a service of xmpp-client and a proto of tcp.

Parameters

adh	The result handler.
domain	The domain to resolve SRV records for.
logInstance	A LogSink to use for logging.
context	User-supplied context information.
