::YARD::Handlers::Base - Inherited

.clear_subclasses

Clear all registered subclasses.

.handlers,
.handles

Declares the statement type which will be processed by this handler.

.handles?

This class is implemented by ::YARD::Handlers::Ruby::Base and Base.

.in_file

Declares that a handler should only be called when inside a filename by its basename or a regex match for the full path.

.inherited, .matches_file?, .new,
.process

Generates a #process method, equivalent to +def process; ...

.subclasses

Returns all registered handler subclasses.
