Class Inheritance

extends Object

java.lang.Object
org.jruby.parser.ScopedParserState

Imports

org.jruby.Ruby, .RubySymbol, org.jruby.common.IRubyWarnings, java.util.HashMap, .HashSet, .Map, .Set

Each scope while parsing contains extra information as part of the parsing process. This class holds this instead of StaticScope which will outlive parsing.
