Class Checksum

java.lang.Object

org.spdx.rdfparser.model.RdfModelObject

org.spdx.rdfparser.model.Checksum

All Implemented Interfaces:

Cloneable, Comparable<Checksum>, IRdfModel

public class Checksum
extends RdfModelObject
implements Comparable<Checksum>

A Checksum is value that allows the contents of a file to be authenticated. Even small changes to the content of the file will change its checksum. This class allows the results of a variety of checksum and cryptographic message digest algorithms to be represented.

                                                  Checksum checksum)
                                                              throws InvalidSPDXAnalysisException

Throws:

InvalidSPDXAnalysisException

getPropertiesFromModel

public void getPropertiesFromModel()
                            throws InvalidSPDXAnalysisException

Description copied from class: RdfModelObject

Fetch all of the properties from the model and populate the local Java properties

Specified by:

getPropertiesFromModel in class RdfModelObject

Throws:

InvalidSPDXAnalysisException

getAlgorithm

public Checksum.ChecksumAlgorithm getAlgorithm()

Returns:

the algorithm

setAlgorithm

public void setAlgorithm(Checksum.ChecksumAlgorithm algorithm)
                  throws InvalidSPDXAnalysisException

Parameters:

algorithm - the algorithm to set

Throws:

InvalidSPDXAnalysisException

getValue

public String getValue()

Returns:

the checksumValue

setValue

public void setValue(String checksumValue)

Parameters:

checksumValue - the checksumValue to set

verify

public List<String> verify()

Specified by:

verify in interface IRdfModel

Returns:

List of validation errors for any non SPDX compliant properties.

getUri

public String getUri(IModelContainer modelContainer)

Description copied from class: RdfModelObject

Get the URI for this RDF object. Null if this is for an anonomous node.

Specified by:

getUri in class RdfModelObject

Returns:

getType

public com.hp.hpl.jena.rdf.model.Resource getType(com.hp.hpl.jena.rdf.model.Model model)

Specified by:

getType in class RdfModelObject

Returns:
