  com.metamatrix.query.sql.util.ElementSymbolOptimizer

public class ElementSymbolOptimizer
extends java.lang.Object

The ElementSymbolOptimizer can be used to modify the appearance of the elements in a command. The operations will be performed on the command and all embedded subcommands, but not any further than that. This class should only be used on commands that have been resolved, as unresolved commands do not contain enough metadata to determine the proper fully qualified or optimized element form.
