Constructor & Destructor Documentation

DocumentStructureDiff()

org.corpus_tools.salt.util.internal.DocumentStructureDiff.DocumentStructureDiff	(	SDocumentGraph	template,
		SDocumentGraph	other
	)

Initializes Diff object with the two graphs template and other.

Parameters

template
other

Member Function Documentation

compareLayers()

boolean org.corpus_tools.salt.util.internal.DocumentStructureDiff.compareLayers ( SDocumentGraph  template, SDocumentGraph  other, Boolean  diff  )

protected

Compares all layers in template graph with all layers in other graph and searches for isomorphic partners.

To layers are isomorph, when have the same name and contain the same number of nodes and relations and have the same labels.
When diff is true, the return value is not necessarily correct, since in that case the differences in getDifferences() is computed. To check the isomorphie there must be no differences.

Parameters

template
other
diff

Returns

compareRelations()

boolean org.corpus_tools.salt.util.internal.DocumentStructureDiff.compareRelations ( SDocumentGraph  template, List<? extends SRelation >  templateRels, SDocumentGraph  other, List<? extends SRelation >  otherRels, Boolean  diff  )

protected

Compares all SPointingRelation of other and template graph.

When diff is true, the return value is not necessarily correct, since in that case the differences in getDifferences() is computed. To check the isomorphie there must be no differences.

Parameters

template
other
diff

Returns

findDiffs()

boolean org.corpus_tools.salt.util.internal.DocumentStructureDiff.findDiffs ( boolean  diffsRequested )

protected

Compares the set graphs and returns if they are isomorphic or not.

If graphs are not isomporphic, this method finds and records all differences and lists them. This means the entire graphs have to be compared and could slow down the computation. If you are only interested in the result and not in the particular differences, use method isIsomorph().

Parameters

diffsRequested

if false, only isomorphie is computed, which makes the process faster but does not collect all differences

Returns

true, if graphs are isomorphic, false otherwise.
