本文整理了Java中org.apache.brooklyn.api.entity.Entity.getChildren()方法的一些代码示例，展示了Entity.getChildren()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。Entity.getChildren()方法的具体详情如下：
包路径：org.apache.brooklyn.api.entity.Entity
类名称：Entity
方法名：getChildren

Entity.getChildren介绍

[英]Return the entities that are children of (i.e. "owned by") this entity
[中]返回该实体的子实体（即“拥有者”）

protected void setEntityAfterSubscribingProducerChildrenEvents() {
  for (Entity child : Iterables.filter(producer.getChildren(), entityFilter)) {
    addProducerChild(child);
  }
}

/** walks the hierarchy (depth-first) at root (often an Application) looking for
 * an entity matching the given ID or name; returns the first such entity, or null if none found
 **/

  for (Entity child: root.getChildren()) {
    Entity result = searchForEntityNamed(child, entity);
    if (result!=null) return result;
  }
  return null;
}
