Class EmptyBasicBlockEnumeration

java.lang.Object
  org.jikesrvm.compilers.opt.ir.EmptyBasicBlockEnumeration

All Implemented Interfaces:

Enumeration<BasicBlock>, BasicBlockEnumeration

 class EmptyBasicBlockEnumeration
extends Object
implements BasicBlockEnumeration

This class is used only for the pre-allocated empty enumeration in BasicBlockEnumeration. It cannot be an anonymous class in BasicBlockEnumeration because BasicBlockEnumeration is an interface, and when javadoc sees the anonymous class, it converts it into a private member of the interface. It then complains that interfaces cannot have private members. This is truly retarded, even by Java's low standards.
