Class TextBasedPhysicalPlanPrinterImpl

java.lang.Object

se.liu.ida.hefquin.engine.queryplan.utils.BaseForTextBasedPlanPrinters

se.liu.ida.hefquin.engine.queryplan.utils.TextBasedPhysicalPlanPrinterImpl

All Implemented Interfaces:

PhysicalPlanPrinter

public class TextBasedPhysicalPlanPrinterImpl
extends BaseForTextBasedPlanPrinters
implements PhysicalPlanPrinter

Internally, the functionality of this class is implemented based on a PhysicalPlanVisitor, which makes sure that we get a compiler error whenever we add a new type of logical operator but forget to extend this class here to cover that new operator.

Method Details

print

public void print(PhysicalPlan plan,
 PrintStream out)

Description copied from interface: PhysicalPlanPrinter

Prints the given plan to the given stream.

Specified by:

print in interface PhysicalPlanPrinter

planWalk

public void planWalk(PhysicalPlan plan,
 int planNumber,
 int planLevel,
 int numberOfSiblings,
 TextBasedPhysicalPlanPrinterImpl.OpPrinter opPrinter,
 String rootOpIndentString)

This method recursively goes through a plan, and appends specific strings to a print stream.

Parameters:

plan - The current plan (root operator) that will be formatted.

planNumber - The number of a plan in terms of its super plan.

planLevel - The depth of the root operator in a plan.

numberOfSiblings - The number of sibling plans of a plan.

opPrinter - The helper object for the printing.
