Method Detail

findSailInStack

public static Sail findSailInStack(Sail topSail,
                                   Class sailClass)

Searches a stack of Sails from top to bottom for a Sail that is an instance of the suppied class or interface. The first Sail that matches (i.e. the one closest to the top) is returned.

Parameters:

topSail - The top of the Sail stack.

sailClass - A class or interface.

Returns:

A Sail that is an instance of sailClass, or null if no such Sail was found.

modelsEqual

public static boolean modelsEqual(RdfSource rdfSource1,
                                  RdfSource rdfSource2)

Compares the models of two RdfSource objects and returns true if they are equal. Models are equal if they contain the same set of statements. bNodes IDs are not relevant for model equality, they are mapped from one model to the other by using the attached properties.

isSubset

public static boolean isSubset(RdfSource rdfSource1,
                               RdfSource rdfSource2)

Compares the models of two RdfSource objects and returns true if rdfSource1 is a subset of rdfSource2.
