Environment.getCurrentDirectiveCallPlace介绍

[英]Gets the currently executing custom directive's call place information, or null if there's no executing custom directive. This currently only works for calls made from templates with the syntax. This should only be called from the TemplateDirectiveModel that was invoked with , otherwise its return value is not defined by this API (it's usually null).
[中]获取当前正在执行的custom指令的调用位置信息，如果没有正在执行的自定义指令，则为null。这目前仅适用于使用语法的模板进行的调用。只能从调用的TemplateDirectiveModel调用它，否则它的返回值不由该API定义（通常为null）。
