Method Details

create

public static RowSet create(List<Var> vars,
 Iterator<Binding> iterator)

hasNext

public boolean hasNext()

Specified by:

hasNext in interface Iterator<Binding>

Specified by:

hasNext in interface RowSet

next

public Binding next()

Specified by:

next in interface Iterator<Binding>

Specified by:

next in interface RowSet

getResultVars

public List<Var> getResultVars()

Specified by:

getResultVars in interface RowSet

rewindable

public RowSetRewindable rewindable()

Description copied from interface: RowSet

Create a RowSetRewindable from the current position to the end. This consumes this RowSet - the iterator will have ended after a call to this method.

Specified by:

rewindable in interface RowSet

getRowNumber

public long getRowNumber()

Description copied from interface: RowSet

Return the row number. The first row is row 1.

Specified by:

getRowNumber in interface RowSet

close

public void close()

Description copied from interface: RowSet

Normally a RowSet is processed until complete which implicitly closes any underlying resources. This "close" operation exists to explicitly end use of the RowSet in cases where it does happen. There is no need to close RowSets normally - it is the QueryExec that should be closed.

Specified by:

close in interface org.apache.jena.atlas.lib.Closeable

Specified by:

close in interface RowSet

forEachRemaining

public void forEachRemaining(Consumer<? super Binding> action)

Specified by:

forEachRemaining in interface Iterator<Binding>
