JDBC Metadata - Oracle

In the following code using JDBC against Oracle, when the metadata is retrieved using the getMetaData() call, does this make a call back to the Oracle database or is this data already local in memory following the creation of the ResultSet. We are trying to determine if it pays to cache and reuse the ResultSetMetaData object locally, since we may be accessing the same table multiple times.
// shadowRs is a ResultSet from the execution of a "select * from <table>" query
ResultSetMetaData rsmd = shadowRs.getMetaData();
I agree. Here's the link:
