- Class Summary
  Class | Description
  --- | ---
  AnnotationVisitor | An Annotation visitor responsible for: reading annotation metadata (@Retention, @Target, attribute types) verify that an `AnnotationNode` conforms to annotation meta enhancing an `AnnotationNode` AST to reflect real annotation meta
  AsmClassGenerator | Generates Java class versions of Groovy classes using ASM.
  BytecodeExpression | Represents some custom bytecode generation by the compiler
  BytecodeInstruction | Helper class used by the class generator.
  BytecodeSequence | This class represents a sequence of BytecodeInstructions or ASTNodes.
  ClassCompletionVerifier | Checks that a class satisfies various conditions including: Incorrect class or method access modifiers No abstract methods appear in a non-abstract class Existence and correct visibility for inherited members Invalid attempts to override final members
  ClassGenerator | Abstract base class for generator of Java class versions of Groovy AST classes
  DummyClassGenerator | To generate a class that has all the fields and methods, except that fields are not initialized and methods are empty.
  EnumCompletionVisitor | Enums have a parent constructor with two arguments from java.lang.Enum.
  EnumVisitor |
  ExtendedVerifier | A specialized Groovy AST visitor meant to perform additional verifications upon the current AST.
  FinalVariableAnalyzer |
  GeneratorContext | A context shared across generations of a class and its inner classes
  InnerClassCompletionVisitor |
  InnerClassVisitor |
  InnerClassVisitorHelper |
  ReturnAdder | Utility class to add return statements.
  VariableScopeVisitor | Initializes the variable scopes for an AST.
  Verifier | Verifies the AST node and adds any default AST code before bytecode generation occurs.
  VerifierCodeVisitor | Performs various checks on code inside methods and constructors including checking for valid field, variables names etc. that would otherwise lead to invalid code.
