Direct Known Subclasses:

SharedScopeBlock

public class InterpretedBlock
extends ContextAwareBlockBody

This branch of the BlockBody hierarchy represents an interpreted block that passes its AST nodes to the interpreter. It forms the top of the hierarchy of interpreted blocks. In a typical application, it is the most heavily consumed type of block.
