States. A table that defines class instances states available within this life cycle. Each state is defined by:
Name. State name.
Description. Human-readable state description.
Entrance Condition. An expression that should return null or empty string if a class instance may currently switch to a new state and error message otherwise. An entrance condition of the new state is evaluated on any state transition.
Exit Condition. An expression that should return null or empty string if a class instance may currently exit its current state and error message otherwise. An exit condition of the new state is evaluated on any state transition.
Entrance Bindings. A list of bindings that change fields of a class instance once it enters a new state. Each binding is defined by a Target field and an Expression that should provide new field value. On any state transition all entrance bindings of the new state are processed.
Exit Bindings. A list of bindings that change fields of a class instance once it exits its current state. Each binding is defined by a Target field and an Expression that should provide new field value. On any state transition all exit bindings of the current state are processed.
Fill Settings. A table that defines which fields of the class should be defined by an operator during a state transition. For each class field, this table defines whether it should be filled On Entrance of the state and On Exit of the state.
State Transitions. A table that defines allowed transitions between class instance States. The transitions table has a dedicated cell for a transition between any two defined States. The cell value should define a human-readable transition name.
