Re: how to get the type of an attribute in code

we're implementing the google wire protocol for google visualizations.
we're using ERRest to get the data we want to visualise, and we're
writing a custom errest writer to output the data in the format we
need. part of the process is to produce a DataTable that a google
library then converts to wire data. as part of that process we need to
know what the value type of the attributes we're using.

we're just looking at pascal's suggestion which looks pretty smack on
for what we need.
