Methods

addHandler(EventHandler<TState> handler) → void
Add a handler to the composite
apply(TState currentState, Event event) → TState
Apply an event to the current state and return the new state This is the core method that updates state based on events
override
canApply(Event event) → bool
Check if this handler can apply the given event Override to provide custom event routing logic
override
checkInvariants(TState newState, Event event) → bool
Check business invariants after applying event Override to implement domain-specific invariants
inherited
getCustomValidationErrors(TState currentState, Event event) → List<String>
Override in subclasses to provide custom validation errors
inherited
getInvariantViolations(TState newState, Event event) → List<String>
Get invariant violations Override to provide specific invariant violation messages
inherited
getValidationErrors(TState currentState, Event event) → List<String>
Get validation errors for an event Override to provide custom validation errors
inherited
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
process(TState currentState, Event event) → EventResult<TState>
Apply an event with full validation and error handling This is the main entry point for event application
inherited
removeHandler(EventHandler<TState> handler) → void
Remove a handler from the composite
toString() → String
A string representation of this object.
inherited
validateEvent(TState currentState, Event event) → bool
Validate an event before applying Override to provide custom validation logic
inherited

Operators
