Class SnippetBuilder

java.lang.Object

org.drools.template.model.SnippetBuilder

public class SnippetBuilder
extends java.lang.Object

This utility class exists to convert rule script snippets to actual code. The snippets contain place holders for values to be substituted into. See the test case for how it really works !

Snippet template example: "something.getBlah($param)" $param is the "place holder". This will get replaced with the "cellValue" that is passed in.

12-Oct-2005 change: moved from regex to using simple character based interpolation. Regex was overkill and couldn't not quite get it right.
