Static Properties

I recently finished running through the tutorial for creating TheSimplestLanguage.  My question is why does the Java code generated in IDEA for TextConcept use a static field to represent the "myText" property?  I would think each instance of that concept would want to store a different value for that property.

Hello, William,

It generates static fields because it is constant and MPS uses this

constant in field accessors. It has generated code like this :

   public String getName() {

     return this.getProperty(BaseConcept.NAME);


   public void setName(String value) {

     this.setProperty(BaseConcept.NAME, value);


MPS uses map to store node properties so we have to key to access it.

This generated constant is this key. So everything is correct.
