Interface Flags<T extends LexicalContextNode>

Type Parameters:
T - lexical context node that can have flags set during code generation
All Known Implementing Classes:
Block, FunctionNode
public interface Flags<T extends LexicalContextNode>
Interface implemented by all nodes that have flags in a lexical context. This is needed as we sometimes have to save the setting of flags in the lexical context until a block is completely finished and its final version (after multiple copy on writes) is placed in the lexical context
