public class AbstractTypeCheckingExtension extends TypeCheckingExtension

Custom type checking extensions may extend this method in order to benefit from a lot of support methods.

The methods found in this class are made directly available in type checking scripts through the `GroovyTypeCheckingExtensionSupport` class.

    public MethodNode makeDynamic(MethodCall call)
    Used to instruct the type checker that the call is a dynamic method call. Calling this method automatically sets the handled flag to true. The expected return type of the dynamic method call is Object.
    Parameters:
      `call` - the method call which is a dynamic method call
    Returns:
      a virtual method node with the same name as the expected call

  - ### makeDynamic

    public MethodNode makeDynamic(MethodCall call, ClassNode returnType)
    Used to instruct the type checker that the call is a dynamic method call. Calling this method automatically sets the handled flag to true.
    Parameters:
      `call` - the method call which is a dynamic method call
      `returnType` - the expected return type of the dynamic call
    Returns:
      a virtual method node with the same name as the expected call

  - ### makeDynamic

    public void makeDynamic(PropertyExpression pexp)
    Instructs the type checker that a property access is dynamic, returning an instance of an Object. Calling this method automatically sets the handled flag to true.
    Parameters:
      `pexp` - the property or attribute expression

  - ### makeDynamic

    public void makeDynamic(PropertyExpression pexp, ClassNode returnType)
    Instructs the type checker that a property access is dynamic. Calling this method automatically sets the handled flag to true.

      `returnType` - the type of the property

  - ### makeDynamic

    public void makeDynamic(VariableExpression vexp)
    Instructs the type checker that an unresolved variable is a dynamic variable of type Object. Calling this method automatically sets the handled flag to true.
    Parameters:
      `vexp` - the dynamic variable

  - ### makeDynamic

    public void makeDynamic(VariableExpression vexp, ClassNode returnType)
    Instructs the type checker that an unresolved variable is a dynamic variable.
