Constructor Detail
GroovyScriptEngine
public GroovyScriptEngine(URL[] roots)(Code)
The groovy script engine will run groovy scripts and reload them and their dependencies when they are modified. This is useful for embedding groovy in other containers like games and application servers.
Parameters:
  roots - This an array of URLs where Groovy scripts will be stored. They shouldbe layed out using their package structure like Java classes
