Class OperationHistoryLogger

java.lang.Object

randoop.generation.OperationHistoryLogger

All Implemented Interfaces:

OperationHistoryLogInterface

public class OperationHistoryLogger
extends Object
implements OperationHistoryLogInterface

The working implementation of a OperationHistoryLogInterface that will collect and print the operation history log to the PrintWriter given when constructed.

Field Summary

Fields

Modifier and Type	Field	Description
private Map<TypedOperation,EnumMap<OperationOutcome,Integer>>	operationMap	A sparse representation for the operation-outcome table.
private PrintWriter	writer	The PrintWriter for outputting the operation history as a table.

Constructor Summary

Constructors

Constructor	Description
OperationHistoryLogger(PrintWriter writer)	Creates an OperationHistoryLogger that will write to the given PrintWriter.

Method Summary

Modifier and Type	Method	Description
void	add(TypedOperation operation, OperationOutcome outcome)	Increments the count for operation and outcome.
void	outputTable()	Prints a table showing the counts for each operation-outcome pair in the operation history log.
private Map<OperationOutcome,String>	printHeader(int firstColumnLength)	Writes the header for the operation history table, and constructs a map of format strings for the columns of the table matching the length of the outcome names.
private void	printRow(int firstColumnLength, Map<OperationOutcome,String> formatMap, TypedOperation operation, EnumMap<OperationOutcome,Integer> countMap)	Writes a row for a particular operation consisting of the operation signature and the counts of sequences for each outcome.

Field Detail

writer

private final PrintWriter writer

The PrintWriter for outputting the operation history as a table.

operationMap

private final Map<TypedOperation,EnumMap<OperationOutcome,Integer>> operationMap

A sparse representation for the operation-outcome table. The integer operationMap.get(A).get(B) is the number of times that (A, B) were arguments to add(randoop.operation.TypedOperation, randoop.generation.OperationOutcome).

Constructor Detail

OperationHistoryLogger

public OperationHistoryLogger(PrintWriter writer)

Creates an OperationHistoryLogger that will write to the given PrintWriter.

Parameters:

writer - the PrintWriter for writing the table from the created operation history

Method Detail

add

public void add(TypedOperation operation,
                OperationOutcome outcome)

Description copied from interface: OperationHistoryLogInterface

Increments the count for operation and outcome.

Specified by:

add in interface OperationHistoryLogInterface

Parameters:

operation - the TypedOperation

outcome - the generation outcome for the operation

outputTable

public void outputTable()

Description copied from interface: OperationHistoryLogInterface

Prints a table showing the counts for each operation-outcome pair in the operation history log.

Specified by:

outputTable in interface OperationHistoryLogInterface

printHeader

private Map<OperationOutcome,String> printHeader(int firstColumnLength)

Writes the header for the operation history table, and constructs a map of format strings for the columns of the table matching the length of the outcome names.

Parameters:

firstColumnLength - the width to use for the first column

Returns:

a map from OperationOutcome value to numeric column format for subsequent rows

printRow

private void printRow(int firstColumnLength,
                      Map<OperationOutcome,String> formatMap,
                      TypedOperation operation,
                      EnumMap<OperationOutcome,Integer> countMap)

Writes a row for a particular operation consisting of the operation signature and the counts of sequences for each outcome.

Parameters:

firstColumnLength - the width to use for the first column

formatMap - the map of format strings for the counts for each outcome

operation - the operation for the row

countMap - the map of counts for the operation and each outcome
