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
falseif destination is known to be bad
trueotherwise

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.

◆ server_mode()

virtual mysqlrouter::ServerMode Destination::server_mode ( ) const
inlinevirtual

server-mode of the destination.

may be: unavailable, read-only or read-write.

Reimplemented in MetadataCacheDestination.
