Method Detail

arraysEqual

public static boolean arraysEqual(Object[] array1,
                                  Object[] array2)

Compares 2 arrays to see if thier content is the same independent of order and considering nulls

Parameters:

array1 -

array2 -

Returns:

stringsEquivalent

public static boolean stringsEquivalent(String s1,
                                        String s2)

Strings are considered equivalent if they are equal, or if they are null and/or empty (null and empty strings are considered equivalent) linefeeds are also normalized (e.g. \r\n is the same as \r)

Parameters:

s1 -

s2 -

Returns:

arraysEquivalent

public static boolean arraysEquivalent(IRdfModel[] array1,
                                       IRdfModel[] array2)

Compares 2 arrays to see if the property values for the element RdfModelObjects are the same independent of order and considering nulls

Parameters:

array1 -

array2 -

Returns:

equivalentConsideringNull

public static boolean equivalentConsideringNull(IRdfModel o1,
                                                IRdfModel o2)

Compares the properties of two RdfModelObjects considering possible null values

Parameters:

o1 -

o2 -

Returns:

findDuplicateResource

public static org.apache.jena.rdf.model.Resource findDuplicateResource(IModelContainer modelContainer,
                                                                       String uri)

Search the model to see if there is a duplicate resource either based on the URI or based on other information. Subclasses may choose to override this method to prevent duplicate resource from being created with the same properties.

Parameters:

modelContainer -

uri -

Returns:

Any duplicate resource found. Null if no duplicate resource was found.

Throws:

InvalidSPDXAnalysisException
