C# Class Metrics.QualityCalculator

This static class contains methods to calculate various component of the Quality Coefficient

Public Methods

Method	Description
calculateFileQuality ( String filepath ) : QualityCoefficient	Calculates only the File Quality component of the Quality Coefficient
calculatePeerQuality ( int buffered, int queueSize ) : QualityCoefficient	Calculates only the Peer Quality component of the Quality Coefficient
calculateQualityCoefficient ( String searchString, String tags, int buffered, int queueSize, String filepath ) : QualityCoefficient	Calculates all components of the Quality Coefficient. This method extact file quality information directly from the file itself.
calculateQualityCoefficient ( String searchString, String tags, int buffered, int queueSize, int bitrate, int channelmode, int samplerate ) : QualityCoefficient	Calculates all components of the Quality Coefficient. This method needs file quality information to be passed as arguments.
calculateSearchAffinity ( String searchString, String tags ) : QualityCoefficient	Calculates only the Search Affinity Component of the Quality Coefficient.

Method	Description
calculateAFF ( String searchString, String tags ) : double	Calculates the affinity coefficient of a tag sets with a given search string. For implementation details read the Wiki Page for this coefficient (http://code.google.com/p/p2p-player/wiki/ImplicitQoS#Coefficiente_di_Affinità)
calculateFQ ( String filepath ) : FileQualityCoefficient	Calculates the File Quality Coefficient extracting information from the MPEG file Header. For implementation details read the Wiki Page for this coefficient (http://code.google.com/p/p2p-player/wiki/ImplicitQoS#Coefficiente_di_Qualità_del_File)
calculateFQ ( int bitrate, int channelmode, int samplerate ) : FileQualityCoefficient	Returns an object of type FileQualityCoefficient with the given components
calculatePQ ( int buffered, int queueSize ) : double	Calculates Peer Quality Coefficient

Calculates only the File Quality component of the Quality Coefficient

public static calculateFileQuality ( String filepath ) : QualityCoefficient
filepath	String	Path of the file to analyze
return	QualityCoefficient

Calculates only the Peer Quality component of the Quality Coefficient
