Method Detail

update

public void update(ServiceSpecification specification)

Description copied from interface: SpecificationChecksumCalculator

Updates the checksum of the provided specification. Throws a runtime exception if the calculation fails, e.g. the specification language is not supported.

Specified by:

update in interface SpecificationChecksumCalculator

Parameters:

specification - The performance specification.

calculate

public long calculate(ServiceSpecification specification)

Description copied from interface: SpecificationChecksumCalculator

Calculates the checksum for the provided specification. Throws a runtime exception if the calculation fails, e.g. the specification language is not supported.

Specified by:

calculate in interface SpecificationChecksumCalculator

Parameters:

specification - The performance specification.

updateChecksumWithSignature

protected void updateChecksumWithSignature(Checksum checksum,
                                           org.palladiosimulator.pcm.repository.Signature signature)

Updates the checksum with details about the signatures.

Parameters:

checksum - The checksum.

signature - The signature.

updateChecksumWithSignature

protected void updateChecksumWithSignature(Checksum checksum,
                                           org.palladiosimulator.pcm.resourcetype.ResourceSignature signature)

Updates the checksum with details about the signatures.

Parameters:

checksum - The checksum.

signature - The signature.

identify

public String identify()

Specified by:

identify in interface SpecificationChecksumCalculator

Returns:

The unique identifier for this algorithm.

updateChecksum

public static void updateChecksum(Checksum checksum,
                                  String string)

Updates checksum with the given string.

Parameters:

checksum - Checksum generator and storage.

string - String used to update the checksum.
