Estimated hours taken: 10. Classes used by the Java backend, particularly in the implementation of RTTI. java/Compare.java: java/Unify.java: New files. Java classes for implementation of wrapper classes around the builtin `unify'and `compare' predicates. java/JavaInternal.java: New file. Java class for storing runtime information such as command line arguments. java/DuExistInfo.java: java/DuExistLocn.java: java/DuFunctorDesc.java: java/DuPtagLayout.java: java/EnumFunctorDesc.java: java/NotagFunctorDesc.java: java/ProcAddr.java: java/PseudoTypeInfo.java: java/Sectag_Locn.java: java/TypeCtorInfo_Struct.java java/TypeCtorRep.java: java/TypeFunctors.java: java/TypeLayout.java: New files. Java classes for implementing Mercury RTTI. java/UnreachableDefault.java: New file. Runtime exception that signals that unreachable default case in a switch statement has been reached. runtime/mercury_type_info.h: Update comments to mention that Java runtime classes will need to be altered if structures in this file are.

|
// pseudo function pointers (which we don't have in Java). The original
|
|
// predicate can be called via the `call' method. This interface should
|
|
// not be used for the `compare' and `unify' special predicates as the
|
|
// `Unify' and `Compare' interfaces perform as similar function for them.
