本文整理了Java中org.eclipse.jface.bindings.Binding.getParameterizedCommand()方法的一些代码示例，展示了Binding.getParameterizedCommand()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。Binding.getParameterizedCommand()方法的具体详情如下：
包路径：org.eclipse.jface.bindings.Binding
类名称：Binding
方法名：getParameterizedCommand

Binding.getParameterizedCommand介绍

[英]Returns the parameterized command to which this binding applies. If the identifier is null, then this binding is "unbinding" an existing binding.
[中]返回应用此绑定的参数化命令。如果标识符为null，则此绑定是“解除绑定”现有绑定。

  1. private ParameterizedCommand getCommand(Object element) {
