Class ReaderBSH

java.lang.Object

de.jreality.reader.ReaderBSH

All Implemented Interfaces:

SceneReader

public class ReaderBSH
extends Object
implements SceneReader

Reader for bsh script files. It creates an bsh.Interpreter instance, see www.beanshell.org for details. In this instance there is a SceneGraphComponent registered as "root", to which the script should attatch the scene parts. Example script:

 a=new Appearance();
 a.setAttribute("plogonShader.diffuseColor", new java.awt.Color(77,66,44,72));
 root.setAppearance(a);
 root.setGeometry(new CatenoidHelicoid(10));
 

For security reasons, this reader sets up a SecurityManager and a restricting Policy for the codebase of the bsh.jar URL. For this to work the bsh jar must NOT be in the classpath. Pass the location of the bsh.jar file as System property, i.e.:

 -Djreality.bsh.jar=file:///opt/jars/bsh-1.3b2.jar
