Constructor Summary

FarragoTestPlanner(HepProgram program, FarragoPreparingStmt stmt)

Method Summary

void	beginMedPluginRegistration(String serverClassName) Notifies this planner that registration for a particular SQL/MED plugin is about to start, meaning the plugin might call the planner via methods such as RelOptPlanner.addRule(org.eigenbase.relopt.RelOptRule).
void	endMedPluginRegistration() Notifies this planner that registration has ended for the SQL/MED plugin whose identity was last passed to beginMedPluginRegistration.
JavaRelImplementor	getJavaRelImplementor(RelNode rel) Retrieves an implementor appropriate for the context in which this planner was created.
FarragoSessionPreparingStmt	getPreparingStmt()

beginMedPluginRegistration

public void beginMedPluginRegistration(String serverClassName)

Description copied from interface: FarragoSessionPlanner

Notifies this planner that registration for a particular SQL/MED plugin is about to start, meaning the plugin might call the planner via methods such as RelOptPlanner.addRule(org.eigenbase.relopt.RelOptRule).

Parameters:

serverClassName - name of class implementing FarragoMedDataServer

endMedPluginRegistration

public void endMedPluginRegistration()

Description copied from interface: FarragoSessionPlanner

Notifies this planner that registration has ended for the SQL/MED plugin whose identity was last passed to beginMedPluginRegistration.

Specified by:

endMedPluginRegistration in interface FarragoSessionPlanner

getJavaRelImplementor

public JavaRelImplementor getJavaRelImplementor(RelNode rel)

Description copied from interface: RelOptPlanner

Retrieves an implementor appropriate for the context in which this planner was created.

Specified by:

getJavaRelImplementor in interface RelOptPlanner

Overrides:

getJavaRelImplementor in class AbstractRelOptPlanner
