Member Function Documentation

connect_status()

virtual void Destination::connect_status ( std::error_code  )

inlinevirtual

status of the last failed connect().

called by MySQLRouting after a connect() to all addresses of the destination failed.

Reimplemented in FirstAvailableDestination, MetadataCacheDestination, and StateTrackingDestination.

good()

virtual bool Destination::good ( ) const

inlinevirtual

check if the destination is "good".

If the destination is not "good", it will be skipped by MySQLRouting.

Return values

false	if destination is known to be bad
true	otherwise

Reimplemented in StateTrackingDestination.

hostname()

std::string Destination::hostname ( ) const

inline

hostname to connect to.

id()

std::string Destination::id ( ) const

inline

unique, opaque identifier of a destination.

used by connection container to find allowed destinations.

port()

uint16_t Destination::port ( ) const

inlinenoexcept

TCP port to connect to.
