 Class returnType)

coerceResult

public static void coerceResult(SkinnyMethodAdapter mv,
 Class returnType,
 boolean doReturn)

calcBaseIndex

public static int calcBaseIndex(Class[] params,
 int baseIndex)

makeConcreteConstructorSwitch

public static void makeConcreteConstructorSwitch(org.objectweb.asm.ClassWriter cw,
 PositionAware initPosition,
 int superpos,
 boolean hasParent,
 RubyClass.ConcreteJavaReifier cjr,
 JavaConstructor[] constructors)

Main switch constructor. Required for concrete reification

makeConcreteConstructorIROProxy

public static void makeConcreteConstructorIROProxy(org.objectweb.asm.ClassWriter cw,
 PositionAware initPosition,
 RubyClass.ConcreteJavaReifier cjr)

Public access for IRubyObject constructor

makeConcreteConstructorProxy

public static String makeConcreteConstructorProxy(org.objectweb.asm.ClassWriter cw,
 PositionAware initPosition,
 boolean hasRuby,

 boolean nested)

Defines a constructor that delegates to the main switch constructor

Parameters:

cw - class builder

initPosition - source code position of initialize

hasRuby - If this method accepts ruby & rubyclass on the end (auto-added)

ctorTypes - signature, minus any ruby arguments

nested - If this is a nested/secondary ruby class ([ruby <]+ ruby < java )
