TapQuery implementation for ADQL query processing. The default implementation
validates the query against the TapSchema, converts wildcards in the select
list to a fixed list of columns, and extracts the select list so it can be
matched to TapSchema.columns to support output of the ResultSet. In addition,
this implementation only allows BLOB and CLOB column references in the select
list.
This class supports extension by delegating calls to a subclass of itself
named ca..nrc.cadc.tap.impl.AdqlQueryImpl. Delegate implementation
is optional.
