Package org.spdx.utility.verificationcode

Class VerificationCodeGenerator

java.lang.Object

org.spdx.utility.verificationcode.VerificationCodeGenerator

public class VerificationCodeGenerator
extends Object

Generates a package verification code from a directory of source code or an array of SPDXFiles. A class implementing the IFileChecksumGenerator is supplied as a parameter to the constructor. The method getFileChecksum is called for each file in the directory. This can be used as a hook to capture all files in the directory and capture the checksum values at a file level.

generatePackageVerificationCode

public SpdxPackageVerificationCode generatePackageVerificationCode(SpdxFile[] spdxFiles,
 String[] skippedFilePaths,
 IModelStore modelStore,
 String documentUri)
                                                            throws NoSuchAlgorithmException,
InvalidSPDXAnalysisException

Generate the SPDX Package Verification Code from an array of SPDXFiles

Parameters:

spdxFiles - Files to generate the VerificationCode from

skippedFilePaths - File path names to not include in the VerificationCode

modelStore - where the resultant VerificationCode is store

documentUri - document URI where the VerificationCode is stored

Returns:

VerificationCode based on all files in spdxFiles minus the skippedFilePaths

Throws:

NoSuchAlgorithmException

InvalidSPDXAnalysisException

IOException,
InvalidSPDXAnalysisException

Generate the SPDX Package Verification Code from a directory of files included in the archive

Parameters:

sourceDirectory -

modelStore - where the resultant VerificationCode is store

documentUri - document URI where the VerificationCode is stored

Returns:

PackageVerificationCode based on the files in the sourceDirectory

Throws:

InvalidSPDXAnalysisException

Parameters:

fileChecksums - used to create the verification code value

skippedFilePaths - list of files skipped when calculating the verification code
