Method Detail

match

public boolean match(org.wikidata.wdtk.datamodel.interfaces.Statement existing,
                     org.wikidata.wdtk.datamodel.interfaces.Statement added)

Description copied from interface: StatementMerger

Determines if the existing statement matches the statement to add (or remove)

Specified by:

match in interface StatementMerger

Parameters:

existing - the statement currently on the entity

added - the statement to add or remove

Returns:

merge

public org.wikidata.wdtk.datamodel.interfaces.Statement merge(org.wikidata.wdtk.datamodel.interfaces.Statement existing,
                                                              org.wikidata.wdtk.datamodel.interfaces.Statement added)

Description copied from interface: StatementMerger

Return the result of merging the statement to add with the existing statement. This method can assume that the two statements are matching (i.e. the method above has returned true on them).

Specified by:

merge in interface StatementMerger

Parameters:

existing - the statement currently on the entity

added - the statement to add or remove

Returns:

the merged statement obtained out of the two

getValueMatcher

public ValueMatcher getValueMatcher()

match

public boolean match(org.wikidata.wdtk.datamodel.interfaces.Snak existingSnak,
                     org.wikidata.wdtk.datamodel.interfaces.Snak addedSnak)

Matches two snaks using the underlying value matcher. The snaks must have the same property id to match.

Parameters:

existingSnak -

addedSnak -

Returns:
