本文整理了Java中org.thymeleaf.Arguments类的一些代码示例，展示了Arguments类的具体用法。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。Arguments类的具体详情如下：
包路径：org.thymeleaf.Arguments
类名称：Arguments

Arguments介绍

[英]Objects of this class contain all the required arguments for template processing.

These objects are created internally by the Template Engine in order to provide processors with all the information they might need for performing their tasks.

Arguments include many attributes, among which some should be used internally only, and never by developers of attribute/element processors. Public attributes are:

  • The Template Engine configuration ( Configuration): #getConfiguration()

  • The template name: #getTemplateName()

  • The Context ( org.thymeleaf.context.IContext): #getContext()

  • The current map of ID Counts (used for adding a unique index to repeated id attributes): #getIdCounts()

  • The Expression roots:

  • For normal (non selected) evaluation (${...} in standard dialect): #getExpressionEvaluationRoot()

    • For selected evaluation (*{...} in standard dialect): #getExpressionSelectionEvaluationRoot()

  • Information about whether processing non-element nodes is allowed at a specific point of a template execution or not (default is to process only elements).
    [中]此类的对象包含模板处理所需的所有参数。
    这些对象由模板引擎在内部创建，以便为处理者提供执行任务所需的所有信息。
    参数包括许多属性，其中一些属性只能在内部使用，属性/元素处理器的开发人员永远不能使用。公共属性包括：
    *模板引擎配置（配置）：#getConfiguration（）
    *模板名称：#getTemplateName（）
    *上下文（org.thymeleaf.Context.IContext）：#getContext（）
    *ID计数的当前映射（用于向重复的ID属性添加唯一索引）：#getIdCounts（）
    *表达式根：
    *对于正常（未选择）求值（${…}标准方言）：#getExpressionEvaluationRoot（）
    对于所选评估（{…}标准方言）：#getExpressionSelectionEvaluationRoot（）
    *有关是否允许在模板执行的特定点处理非元素节点的信息（默认情况下仅处理元素）。

      // processing itself 
      ... 

      // move processing to children, but does not happend if node is marked as skippable 
      doAdditionalProcess(executionArguments, executionArguments.getProcessTextNodes(), executionArguments.getProcessCommentNodes()); 
  }
