The portlet can leverage all the information in the portlet context, like portlet mode, window state, render parameters, or portlet preferences.
Portlet可以利用 Portlet上下文中的所有信息，例如 Portlet模式、窗口状态、呈现参数或 Portlet首选项。
The portlet is free to alter session state or backend state during this phase and associates new render parameters at the end of the action phase.
在此阶段，Portlet可以自由地更改会话状态或后端状态，并在操作阶段结束时关联新呈现参数。
Examples for this include rendering different resources based on the portlet mode, window state, current render parameters, or portlet preferences.
这样的示例包括基于Portlet模式、窗口状态、当前呈现参数或Portlet首选项呈现不同资源。
In general, we recommend that portlets minimize the number and size of render parameters as much as possible so that the risk of invalid URLs decreases.
通常，我们建议Portlet尽可能使呈现参数的数量和长度保持最小，从而降低产生无效url的风险。
This concept means that render parameters can provide the expected user behavior inside portlets for browser operations such as bookmarking and back-button.

As a general rule, use public render parameters where you can, and use portlet events for more complex cases for which render parameters are not sufficient.
根据一般经验，应该在可使用公共呈现参数的场合使用公共呈现参数，并对呈现参数不足够的较复杂情况使用Portlet事件。
A resource URL contains the current transient state of the portlet (portlet mode, window state, render parameters), but cannot set new values for this state.
资源URL包含当前Portlet的瞬时状态(Portlet模式、窗口状态和呈现参数)，但不能为此状态设置新值。
As we have seen from the preceding discussion, public render parameters can be regarded as a more lightweight communication alternative compared to portlet events.
