Detailed Description

This is the abstract base class for slave start until options.

It defines the public interfaces called by slave coordinator.

This class publics three interfaces:

• is_satisfied_at_start_slave It is called just when starting slave coordinator to check if the until condition is already satisfied.
• is_satisfied_before_dispatching_event It is called just after coordinator reads a events from relay log but before it is applied or dispatched.
• is_satisfied_after_dispatching_event It is called just after a event is applied or dispatched by the coordinator.

These three interfaces cover all until options's check requirements.
