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

Binding.getTriggerSequence介绍

[英]Returns the sequence of trigger for a given binding. The triggers can be anything, but above all it must be hashable. This trigger sequence is used by the binding manager to distinguish between different bindings.
[中]返回给定绑定的触发器序列。触发器可以是任何东西，但最重要的是它必须是可散列的。绑定管理器使用此触发序列来区分不同的绑定。
