public class ResultSetMetaDataWrapper
extends GroovyObjectSupport This class defines a wrapper for accessing a specific column in ResultSetMetaData.
This allows iteration over columns using idiomatic Groovy, e.g.:
meta.each {col ->
println col.columnName
}
ResultSetMetaData column methods taking a column index
are available on a column either as a no-arg getter or via a property.
This wrapper is created by an iterator invoked for ResultSetMetaData.
