Class AskResultsMetadata

org.apache.jena.jdbc.results.metadata.AbstractResultsMetadata

org.apache.jena.jdbc.results.metadata.AskResultsMetadata

All Implemented Interfaces:

ResultSetMetaData, Wrapper

public class AskResultsMetadata
extends JenaResultsMetadata

Meta data for AskResults

Note that ASK results are something of a special case because they contain only a single column and we know exactly what the type of the column is, with other forms of results we don't have this luxury and so the JdbcCompatibility levels are used to determine how we report types.
