Examples of bsh.Interpreter

bsh.Interpreter
uate statements and expressions bsh.eval("foo=Math.sin(0.5)"); bsh.eval("bar=foo*5; bar=Math.cos(bar);"); bsh.eval("for(i=0; i<10; i++) { print(\"hello\"); }"); // same as above using java syntax and apis only bsh.eval("for(int i=0; i<10; i++) { System.out.println(\"hello\"); }"); // Source from files or streams bsh.source("myscript.bsh"); // or bsh.eval("source(\"myscript.bsh\")"); // Use set() and get() to pass objects in and out of variables bsh.set( "date", new Date() ); Date date = (Date)bsh.get( "date" ); // This would also work: Date date = (Date)bsh.eval( "date" ); bsh.eval("year = date.getYear()"); Integer year = (Integer)bsh.get("year"); // primitives use wrappers // With Java1.3+ scripts can implement arbitrary interfaces... // Script an awt event handler (or source it from a file, more likely) bsh.eval( "actionPerformed( e ) { print( e ); }"); // Get a reference to the script object (implementing the interface) ActionListener scriptedHandler = (ActionListener)bsh.eval("return (ActionListener)this"); // Use the scripted event handler normally... new JButton.addActionListener( script );
In the above examples we showed a single interpreter instance, however you may wish to use many instances, depending on the application and how you structure your scripts. Interpreter instances are very light weight to create, however if you are going to execute the same script repeatedly and require maximum performance you should consider scripting the code as a method and invoking the scripted method each time on the same interpreter instance (using eval()).
See the BeanShell User's Manual for more information.
