Psych::Handler

        # Psych::Handler < Object

(from ruby core)

Psych::Handler is an abstract base class that defines the events used
when dealing with Psych::Parser.  Clients who want to use Psych::Parser
should implement a class that inherits from Psych::Handler and define
events that they can handle.

Psych::Handler defines all events that Psych::Parser can possibly send
to event handlers.

See Psych::Parser for more details
