Hi,
I have created an AbstractVisitorCompilerStep and have the following
OnBlockExpression:
public override void OnBlockExpression(BlockExpression node)
{
foreach (Statement statement in node.Body.Statements)
{
MethodInvocationExpression method =
(MethodInvocationExpression)((ExpressionStatement) statement).Expression;
foreach(Expression arg in method.Arguments)
{
if ((!(arg is BinaryExpression)) &&
((BinaryExpression)arg).Operator != BinaryOperatorType.ShiftRight)
continue;
var binaryExpression = (BinaryExpression) arg;
}
}
base.OnBlockExpression(node);
}
Do I just create a new BlockExpression and pass it to the base
OnBlockExpression?
Cheers
Paul
