public class EmbedEvalUnitImpl
extends Object
implements EmbedEvalUnit

Implementation of org.jruby.javasupport.JavaEmbedUtils.EvalUnit for embeddiing. This class is created when a Ruby script has been parsed. Once parsed, the script is ready to run many times without parsing.

Users do not instantiate explicitly. Instead, they can get the instance by parsing Ruby script by parse method of ScriptingContainer.
