java - 在 BTrace 中将 char[] 转换为 String

Question

我正在使用 btrace 分析应用程序并面临限制。我尝试获取当前 java.lang.Thread 的名称。通常你可以调用 getName() 但它在 btrace 脚本中是被禁止的(任何调用异常 BTraceUtils)。
知道如何从 char[] 获取字符串吗？

最初的任务是检查线程名称是否包含子字符串，然后才注销跟踪信息(减少输出)。

In particular, a BTrace class

• can not create new objects.
• can not create new arrays.
• can not throw exceptions.
• can not catch exceptions.
• can not make arbitrary instance or static method calls - only the public static methods of com.sun.btrace.BTraceUtils class may be called from a BTrace program.
• can not assign to static or instance fields of target program's classes and objects. But, BTrace class can assign to it's own static fields ("trace state" can be mutated).
• can not have instance fields and methods. Only static public void returning methods are allowed for a BTrace class. And all fields have to be static.
• can not have outer, inner, nested or local classes.
• can not have synchronized blocks or synchronized methods.
• can not have loops (for, while, do..while)
• can not extend arbitrary class (super class has to be java.lang.Object)
• can not implement interfaces.
• can not contains assert statements.
• can not use class literals.
