getLGG

public RDFResourceTree getLGG(RDFResourceTree tree1,
                              RDFResourceTree tree2,
                              boolean learnFilters)

Description copied from interface: LGGGenerator

Returns the Least General Generalization of two RDF resource trees. It can be forced to learn filters on literal values.

Specified by:

getLGG in interface LGGGenerator

Parameters:

tree1 - the first tree

tree2 - the second tree

learnFilters - whether to learn filters on literal values

Returns:

the Least General Generalization

                       TimeUnit timeoutUnits)

Specified by:

setTimeout in interface TimeoutableOperation

stop

public void stop()

Specified by:

stop in interface StoppableOperation

isComplete

public boolean isComplete()

setBlankNodeScope

public void setBlankNodeScope(AbstractLGGGenerator.BlankNodeScope blankNodeScope)
