本文整理了Java中org.hippoecm.repository.api.Workflow.hints()方法的一些代码示例，展示了Workflow.hints()的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。Workflow.hints()方法的具体详情如下：
包路径：org.hippoecm.repository.api.Workflow
类名称：Workflow
方法名：hints

Workflow.hints介绍

[英]The hints method is not an actual workflow call, but a method by which information can be retrieved from the workflow. All implementations must implement this call as a pure function, no modification may be made, nor no state may be maintained and and in principle no additional lookups of data is allowed. This allows for caching the result as long as the document on which the workflow operates isn't modified. By convention, keys that are names or signatures of methods implemented by the workflow provide information to the application program whether the workflow method is available this time, or will result in a WorkflowException. The value for these keys will often be a java.lang.Boolean to indicate the enabled status of the method.

Non-standard keys in this map should be prefixed with the implementation package name using dot seperations.
[中]提示方法不是实际的工作流调用，而是一种可以从工作流中检索信息的方法。所有实现都必须将此调用实现为纯函数，不能进行任何修改，也不能维护任何状态，原则上不允许对数据进行额外的查找。这允许缓存结果，只要工作流操作的文档未被修改。按照惯例，作为工作流实现的方法的名称或签名的密钥将向应用程序提供信息，无论工作流方法这次是否可用，或者是否会导致WorkflowException。这些键的值通常是java。lang.Boolean表示方法的启用状态。
此映射中的非标准键应使用点分隔的实现包名称作为前缀。
