本文整理了Java中bsh.Interpreter.getClassManager()方法的一些代码示例，展示了Interpreter.getClassManager()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。Interpreter.getClassManager()方法的具体详情如下：
包路径：bsh.Interpreter
类名称：Interpreter
方法名：getClassManager

Interpreter.getClassManager介绍

[英]Get the class manager associated with this interpreter (the BshClassManager of this interpreter's global namespace). This is primarily a convenience method.
[中]获取与此解释器关联的类管理器（此解释器的全局命名空间的BshClassManager）。这主要是一种方便的方法。

/**
  Set an external class loader to be used as the base classloader
  for BeanShell.  The base classloader is used for all classloading 
  unless/until the addClasspath()/setClasspath()/reloadClasses()  
  commands are called to modify the interpreter's classpath.  At that 
  time the new paths /updated paths are added on top of the base 
  classloader.
  <p>
  BeanShell will use this at the same point it would otherwise use the 
  plain Class.forName().
  i.e. if no explicit classpath management is done from the script
  (addClassPath(), setClassPath(), reloadClasses()) then BeanShell will
  only use the supplied classloader.  If additional classpath management
  is done then BeanShell will perform that in addition to the supplied
  external classloader.  
  However BeanShell is not currently able to reload
  classes supplied through the external classloader.
