[jboss-dev-forums] [Design the new POJO MicroContainer] - Adding handy isInstance(Object) method to TypeInfo

[alesj]

I'm thinking about adding convenient isInstance method to TypeInfo.
On ClassInfoImpl/JavassistTypeInfo it would use getType::isInstance,
but on PrimitiveInfo it would still look into progression.

The method would hide simple impl detail.

  | TypeInfo ti = ...;
  | Object value = ...; // not null
  | 
  | //long version
  | TypeInfoFactory tif = ti.getTypeInfoFactory();
  | TypeInfo other = tif.getTypeInfo(value.getClass());
  | boolean isInstance = ti.isAssignableFrom(other);
  | 
  | // short
  | boolean isInstance = ti.isInstance(value);
  | 
  | // where this doesn't consider progression
  | boolean isInstance = ti.getType().isInstance(value);
  | 

OK?
