Method Summary

Methods

Modifier and Type	Method and Description
void	callMethod(String methodName) Define action method to be called during transition.
void	evalMvel(String expression) Define mvel action to be performed during transition
void	perform(Action<T,S,E,C> action) Define action to be performed during transition
void	perform(List<? extends Action<T,S,E,C>> actions) Define actions to be performed during transition.

Method Detail

perform

void perform(Action<T,S,E,C> action)

Define action to be performed during transition

Parameters:

action - performed action

perform

void perform(List<? extends Action<T,S,E,C>> actions)

Define actions to be performed during transition. When used in multiple transition builder, the actions will be sequentially assigned to each transition. If actions size is less than transitions size, the last action will be assigned to the rest of transitions. null value in actions will be skipped which means no action will be assigned to corresponding transition.

Parameters:

actions - performed actions

evalMvel

void evalMvel(String expression)

Define mvel action to be performed during transition

Parameters:

expression - mvel expression

callMethod

void callMethod(String methodName)

Define action method to be called during transition. When used in multiple transition builder, the method name can be joined by '|'. Each method action will be sequentially assigned to each transition. If actions size is less than transitions size, the last method action will be assigned to the rest of transitions. '_' represent a place holder which means no method action will be assigned to corresponding transition.

Parameters:

methodName - method name
