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
- Methods needed to implement GroovyObject
- Property accessor methods

transformToPrimitiveConstantIfPossible
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.
