ワークフローには、「ライブラリ」または「特定」の2種類のステップがあります。
「ライブラリ」は module.xml で定義されている Bean であり、再利用できます。'library' Bean を使用すると、人間工学が向上します。パラメーターは定義画面に動的に表示されます。
「特定の」オブジェクトは、そのクラス名によってのみ定義されるBeanです。この場合、表示は動的ではありません。
ステップ | ライブラリ | スペシフィック |
|---|---|---|
スクリプト | ScriptTaskBean | ScriptTask |
条件 | ConditionBean | Condition |
ユーザータスク | UserTask |
次の例のように、スクリプトタスクはメソッドexecuteをオーバーライドする必要があります。
public class NppScriptTask_CreateWorkingBranch extends ScriptTask
{
public void executeScript(ScriptTaskContext aContext) throws OperationException
{
Repository repository = aContext.getRepository();
String initialBranchString = aContext.getVariableString("initialBranch");
AdaptationHome initialBranch = repository.lookupHome(HomeKey.forBranchName(initialBranchString));
if (initialBranch == null)
throw OperationException.createError("Null value for initialBranch");
HomeCreationSpec spec = new HomeCreationSpec();
spec.setParent(initialBranch);
spec.setKey(HomeKey.forBranchName("Name"));
spec.setOwner(Profile.EVERYONE);
spec.setHomeToCopyPermissionsFrom(initialBranch);
AdaptationHome newHome = repository.createHome(spec, aContext.getSession());
//feeds dataContext
aContext.setVariableString("workingBranch", newHome.getKey().getName());
}
}
スクリプトタスクBeanは、次の例のように、メソッドexecuteScriptをオーバーライドする必要があります。
public class ScriptTaskBean_CreateBranch extends ScriptTaskBean
{
private String initialBranchName;
private String newBranch;
public String getInitialBranchName()
{
return this.initialBranchName;
}
public void setInitialBranchName(String initialBranchName)
{
this.initialBranchName = initialBranchName;
}
public String getNewBranch()
{
return this.newBranch;
}
public void setNewBranch(String newBranch)
{
this.newBranch = newBranch;
}
public void executeScript(ScriptTaskBeanContext aContext) throws OperationException
{
final Repository repository = aContext.getRepository();
String initialBranchName = this.getInitialBranchName();
final AdaptationHome initialBranch = repository.lookupHome(HomeKey.forBranchName(initialBranchName));
final HomeCreationSpec spec = new HomeCreationSpec();
spec.setParent(initialBranch);
spec.setKey(HomeKey.forBranchName(XsFormats.SINGLETON.formatDateTime(new Date())));
spec.setOwner(Profile.EVERYONE);
spec.setHomeToCopyPermissionsFrom(initialBranch);
final AdaptationHome branchCreate = repository.createHome(spec, aContext.getSession());
this.setNewBranch(branchCreate.getKey().getName());
}
}
スクリプトタスクBeanは、module.xmlで宣言する必要があります。

<beans>
<bean className="com.orchestranetworks.workflow.genericScriptTask.ScriptTaskBean_CreateBranch">

ビルトインサービスを module.xml で宣言し、ユーザータスクの定義で使用することができます。

GUIは上記の例と非常によく似ています。「UserTask」を拡張して呼び出すクラスを定義するには、フィールド「Rule」に入力する必要があります。
public class NppUserTask_ValidateProduct extends UserTask
{
public void handleWorkItemCompletion(UserTaskWorkItemCompletionContext context)
throws OperationException
{
if (context.getCompletedWorkItem().isRejected())
{
context.setVariableString(NppConstants.VAR_VALIDATION, "KO");
context.completeUserTask();
}
else if (context.checkAllWorkItemMatchStrategy())
{
context.setVariableString(NppConstants.VAR_VALIDATION, "OK");
context.completeUserTask();
}
}
public void handleCreate(UserTaskCreationContext context) throws OperationException
{
CreationWorkItemSpec spec = CreationWorkItemSpec.forOfferring(NppConstants.ROLE_PVALIDATOR);
spec.setNotificationMail("1");
context.createWorkItem(spec);
context.setVariableString(NppConstants.VAR_VALIDATION, "validating");
}
}
メソッドevaluateはオーバーライドする必要があります。
public class NppCondition_IsValidationOK extends Condition
{
public boolean evaluateCondition(ConditionContext context) throws OperationException
{
String validation = context.getVariableString("validationResult");
boolean hasError = "KO".equals(validation);
return !hasError;
}
}
次の例のように、メソッドEvaluationConditionをオーバーライドする必要があります。
public class ConditionBean_IsBranchValid extends ConditionBean
{
private String branchName;
public String getBranchName()
{
return this.branchName;
}
public void setBranchName(String branchName)
{
this.branchName = branchName;
}
public boolean evaluateCondition(ConditionBeanContext aContext) throws OperationException
{
final Repository repository = aContext.getRepository();
Severity severityForValidation = Severity.ERROR;
String branchToTestName = this.getBranchName();
final AdaptationHome branchToTest = repository.lookupHome(HomeKey.forBranchName(branchToTestName));
if (branchToTest.getValidationReportsMap(severityForValidation) != null
&& branchToTest.getValidationReportsMap(severityForValidation).size() > 0)
{
return false;
}
return true;
}
}
条件Beanは、module.xmlで宣言する必要があります。
