  - ### visitMethodCallExpression

    public void visitMethodCallExpression(MethodCallExpression call)
    Attempts to find AstBuilder 'from code' invocations. When found, converts them into calls to the 'from string' approach.
    Specified by:
      `visitMethodCallExpression` in interface `GroovyCodeVisitor`
    Overrides:
      `visitMethodCallExpression` in class `CodeVisitorSupport`
    Parameters:
      `call` - the method call expression that may or may not be an AstBuilder 'from code' invocation.

  - ### addError

    protected void addError(String msg, ASTNode expr)
    Reports an error back to the source unit.
    Parameters:
      `msg` - the error message
      `expr` - the expression that caused the error message.

  - ### convertClosureToSource

    protected String convertClosureToSource(ClosureExpression expression)
    Converts a ClosureExpression into the String source.
    Parameters:
      `expression` - a closure
    Returns:
      the source the closure was created from

  - ### handleTargetMethodCallExpression

    protected abstract boolean handleTargetMethodCallExpression(MethodCallExpression call)

  - ### isBuildInvocation

    protected abstract boolean isBuildInvocation(MethodCallExpression call)
