WorkflowInstanceStatus代码实现
WorkflowInstanceStatus 的代码实现
类定义和构造函数
WorkflowInstanceStatus 代表工作流实例当前状态的快照，包括元数据。
WorkflowInstanceStatus 的实现依然是包装 durabletask，内部是一个 durabletask 的 OrchestrationMetadata，以及 OrchestrationMetadata 携带的 FailureDetails：
import com.microsoft.durabletask.FailureDetails;
import com.microsoft.durabletask.OrchestrationMetadata;
public class WorkflowInstanceStatus {
private final OrchestrationMetadata orchestrationMetadata;
@Nullable
private final WorkflowFailureDetails failureDetails;
public WorkflowInstanceStatus(OrchestrationMetadata orchestrationMetadata) {
if (orchestrationMetadata == null) {
throw new IllegalArgumentException("OrchestrationMetadata cannot be null");
}
this.orchestrationMetadata = orchestrationMetadata;
FailureDetails details = orchestrationMetadata.getFailureDetails();
if (details != null) {
this.failureDetails = new WorkflowFailureDetails(details);
} else {
this.failureDetails = null;
}
}
获取 FailureDetails 之后将转为 dapr 的 WorkflowFailureDetails, 这里的细节在 WorkflowFailureDetails 类实现中展开。
