public class EmbedEvalUnitImpl
extends java.lang.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.

Method Detail

getNode

public Node getNode()

Returns a root node of parsed Ruby script.

Specified by:

getNode in interface EmbedEvalUnit

Specified by:

getScope in interface EmbedEvalUnit

Returns:

a scope to refer local variables

run
