guards property
Guards that will be executing check
when this gets beamed to.
Checks will be executed in order; chain of responsibility pattern.
When some guard returns false
, a candidate will not be accepted
and stack of pages will be updated as is configured in BeamGuard.
Override this in your subclasses, if needed. See BeamGuard.
