Method Details

customReify

public void customReify()

loadRubyObject

protected void loadRubyObject(SkinnyMethodAdapter m)

Loads self (if local) or the rubyObject (if a java proxy) cast to a RubyBasicObject, as everything is a RBO and it has a nicer interface

reify

public byte[] reify()

isRubyObject

protected boolean isRubyObject()

getExtraClinitInfo

protected Object[] getExtraClinitInfo()

extraClinitLookup

protected void extraClinitLookup(SkinnyMethodAdapter m)

Override to save more values from the array in reifyClinit(SkinnyMethodAdapter)

generateSuperBridges

protected void generateSuperBridges(String javaMethodName,
 Class<?>[] methodSignature)

searchInheritedSignatures

protected Collection<Class<?>[]> searchInheritedSignatures(String id,
 Signature arity)

reifyConstructors

protected void reifyConstructors()

generateObjectBarrier

protected void generateObjectBarrier(SkinnyMethodAdapter m)

Generates an init barrier. NOT Thread-safe, but hopefully nobody has threads in their constructor? This is used to ensure that self.to_java is valid if the super ctor calls an abstract method that is re-implemented by ruby

defineInstanceMethods

protected void defineInstanceMethods(ThreadContext context,
 Set<String> instanceMethods)

defineInstanceMethod

protected String defineInstanceMethod(ThreadContext context,
 String id,
 String callid,
 Signature sig,
 PositionAware position,
 Class<?>[] methodSignature)

reifyClinit

public void reifyClinit(SkinnyMethodAdapter m)

This method generates <clinit> by marshaling the Ruby, RubyClass, etc variables through a static map identified by integer in JavaProxyClass. Integers are serializable through bytecode generation so we can share arbitrary objects with the generated class by saving them in getExtraClinitInfo() via JavaProxyClass.addStaticInitLookup(Object...) and JavaProxyClass.getStaticInitLookup(int)

searchClassMethods

protected Collection<Class<?>[]> searchClassMethods(Class<?> clz,
 Signature arity,
 String id,
 HashMap<String,Class<?>[]> options)

rubycall

public void rubycall(SkinnyMethodAdapter m,
 String signature)

allocAndInitialize

protected void allocAndInitialize(SkinnyMethodAdapter m,
 boolean initIfAllowed)

join

public Class[] join(Class[] base,
 Class... extra)
