• FlawlessState::State
• Struct
• Value
• Object

Defined in:

Constructors

• .new(transitions = self.defined_states)

  transitions are a Hash(Symbol,Array(Symbol) which reprsent what a state is allowed to transitio to

Instance Method Summary

• #build_transitions(definitions : Hash(Symbol, Array(Symbol)))

  Create the @state_pairs array of tuples.

• #current_state : Symbol
• #defined_states

  each key results in an array that can be transitioned into.

• #is?(state : Symbol)
• #is_not?(state : Symbol)
• #state_pairs : Array({Symbol, Symbol})
• #state_pairs=(state_pairs : Array(Tuple(Symbol, Symbol)))
• #terminal?(state : Symbol = @current_state)

  A state is termimal if it is has no valid states to transition to (empty arrays in #defined_states) States can be forced to other states with #transition_to!

• #transition_to(new_state : Symbol)

  if a transition is permitted, make it, otherwise raise an exception

• #transition_to!(new_state : Symbol)

  force a transition without checking the validity of the new state
