Hello!

I'm having trouble passing an object to a beanscript interpreter, then calling a method from that object from within a beanscript file.  

I have a class named "Pattern", and I'm trying to send in an object of this class into the Interpreter using the bsh.Interpreter::set(String,Object) method.

Here's "my" code.  (Most of it is copied from an Interpreter wrapper that was posted as part of an example for live coding.)

Here's the basics of the Interpreter wrapper.  

Code:

class Interpreter {
  bsh.Interpreter ip = null;

  Interpreter(){
	ip = new bsh.Interpreter(); 
	ip.eval("import processing.core.*;"); 
  }

  public void setPattern(String name, Pattern obj){
    try{
	ip.set(name, obj);
    } 
    catch(bsh.EvalError e){
	println(e);
    }
  }
}

 

Here's my code that calls it:

Code:

 File setupScript = new File(dataPath("setup.bsh"));

 // draft_sequencer1.get_pattern() returns a Pattern object
 ip.setPattern("p1", draft_sequencer1.get_pattern()); 

 ip.call(setupScript);

 

Here's setup.bsh (my beanscript):

Code:

  p1.shrink(5); // shrink is a method of Pattern

 

Here's the error that I keep getting:

Code:

Sourced file: C:\Documents and Settings\Bret Truchan\My Documents\Processing\Quotile\data\setup.bsh : Error in method invocation: Method shrink( int ) not found in class'Quotile$Pattern' : at Line: 1 : in file: C:\Documents and Settings\Bret Truchan\My Documents\Processing\Quotile\data\setup.bsh : p1 .shrink ( 5 ) 

 

Just for giggles, here's a portion of class Pattern:

Code:

class Pattern
{
  void shrink(int percentage)
  {
    this.stretch(-1 * percentage);
  }
}

 

Any ideas why beanscript is unable to locate the shrink method in p1?
