接口 StatusDecisionStrategy

所有已知实现类:

DefaultStatusDecisionStrategy

public interface StatusDecisionStrategy

Default state machine execution status decision strategy. The strategy is to traverse the execution state of each state executed. If all state are successfully executed the state machine is successfully executed, if there is a state that fails to execute which is for data update, the state machine execution status is considered to be UN (the data is inconsistent), otherwise FA (failure: no data inconsistency)

方法概要

限定符和类型	方法和说明
boolean	decideMachineForwardExecutionStatus(StateMachineInstance stateMachineInstance, Exception exp, boolean specialPolicy) Determine the forward execution state of the state machine
void	decideOnEndState(ProcessContext context, StateMachineInstance stateMachineInstance, Exception exp) Determine state machine execution status when executing to EndState
void	decideOnTaskStateFail(ProcessContext context, StateMachineInstance stateMachineInstance, Exception exp) Determine state machine execution status when executing TaskState error
