BlackboardDecorator

Remarks

The commonest decorator there is, in every reference implementation. Everything it compares is resolved at construction — the key to an index, the constant to bytes — so a test is a span read and a comparison, and never a name lookup.

Fields and properties (2)

• public override ObserverAborts Aborts

  What this may interrupt when the keys it reads change.

• public override ReadOnlySpan<BlackboardKey> ObservedKeys

  The blackboard keys it reads.

  Tests a boolean key.

• public static BlackboardDecorator Number(BlackboardKey key, BlackboardTest test, float value, ObserverAborts aborts = None)

  Compares a numeric key against a constant.

• public static BlackboardDecorator Word(BlackboardKey key, Symbol value, bool equal = true, ObserverAborts aborts = None)

  Compares a symbol key against a constant.

• public static BlackboardDecorator Is(BlackboardKey key, Entity value, bool equal = true, ObserverAborts aborts = None)
