public void generateCanonical(CommandTreeNode rootNode, QueryMetadataInterface metadata, AnalysisRecord analysisRecord, CommandContext context) throws QueryPlannerException, QueryMetadataException, MetaMatrixComponentException
CommandPlanner
Requests that the planner generate the canonical plan(s) for the Command object(s) represented by the CommandTreeNode tree parameter. The canonical plan(s) should be added to the node(s) of the tree rooted at rootNode.
It may or may not make sense for a specific implementation of this
Class to create a canonical plan. It may be that all planning can be done
during the call to CommandPlanner.optimize(com.metamatrix.query.optimizer.CommandTreeNode, com.metamatrix.core.id.IDGenerator, com.metamatrix.query.metadata.QueryMetadataInterface, com.metamatrix.query.optimizer.capabilities.CapabilitiesFinder, com.metamatrix.query.analysis.AnalysisRecord, com.metamatrix.query.util.CommandContext)
