Verifier (Groovy 4.0.23)

org.codehaus.groovy.classgen.Verifier

All Implemented Interfaces and Traits:

GroovyClassVisitor, org.objectweb.asm.Opcodes
```
public class Verifier
extends Object
implements GroovyClassVisitor, org.objectweb.asm.Opcodes
```
Verifies the AST node and adds any default AST code before bytecode generation occurs.
Checks include:
- Methods with duplicate signatures
- Duplicate interfaces
- Reassigned final variables/parameters
- Uninitialized variables
- Bad code in object initializers or constructors
- Mismatches in modifiers or return types between implementations and interfaces/abstract classes
- Invalid record component names
Added code includes:
- Methods needed to implement GroovyObject
- Property accessor methods
- Covariant methods
- Additional methods/constructors as needed for default parameters
- Lookup getter

    Helper method to add a new method to a ClassNode. Depending on the shouldBeSynthetic flag the call will either be made to ClassNode.addSyntheticMethod() or ClassNode.addMethod(). If a non-synthetic method is to be added the ACC_SYNTHETIC modifier is removed if it has been accidentally supplied.

  - public static ConstantExpression transformToPrimitiveConstantIfPossible(ConstantExpression constantExpression)
    
    When constant expressions are created, the value is always wrapped to a non-primitive type. Some constant expressions are optimized to return primitive types, but not all primitives are handled. This method guarantees to return a similar constant expression but with a primitive type instead of a boxed type.
    Additionally, single char strings are converted to 'char' types.
    Parameters:
    constantExpression - a constant expression
    Returns:
    the same instance of constant expression if the type is already primitive, or a primitive constant if possible.
