Class Interpreter

src/bsh/Interpreter.java:97–1290

The BeanShell script interpreter. An instance of Interpreter can be used to source scripts and evaluate statements or expressions. Here are some examples: Interpeter bsh = new Interpreter(); // Evaluate statements and expressions bsh.eval("foo=Math.sin(0.5)"

	See the BeanShell User's Manual for more information.
