Constructor Detail

Bigdata2Sesame2BindingSetIterator

public Bigdata2Sesame2BindingSetIterator(ICloseableIterator<IBindingSet> src)

Parameters:

src - The source iterator (will be closed when this iterator is closed). All bound values in the visited IBindingSets MUST be BigdataValues.

Method Detail

hasNext

public boolean hasNext()
                throws E extends Exception

Specified by:

hasNext in interface info.aduna.iteration.Iteration<org.openrdf.query.BindingSet,E extends Exception>

Throws:

E extends Exception

next

public org.openrdf.query.BindingSet next()
                                  throws E extends Exception

Specified by:

next in interface info.aduna.iteration.Iteration<org.openrdf.query.BindingSet,E extends Exception>

Throws:

E extends Exception

getBindingSet

protected org.openrdf.query.BindingSet getBindingSet(IBindingSet sourceBindingSet)

Aligns a bigdata IBindingSet with the Sesame 2 BindingSet.

Parameters:

sourceBindingSet - A bigdata IBindingSet containing only BigdataValues.

Returns:

The corresponding Sesame 2 BindingSet.

Throws:

IllegalArgumentException - if the argument is null.

ClassCastException - if a bound value is not a BigdataValue.

remove

public void remove()
            throws E extends Exception

Specified by:
