Method Detail

getContext

public RootFragmentContext getContext()

Deprecated.

getSelectionVector2

public SelectionVector2 getSelectionVector2()

Deprecated.

getSelectionVector4

public SelectionVector4 getSelectionVector4()

Deprecated.

getValueVectorById

public <T extends ValueVector> T getValueVectorById(SchemaPath path,
                                                    Class<?> vvClass)

Deprecated.

next

public boolean next()

Deprecated.

Description copied from interface: RootExec

Do the next batch of work.

Specified by:

next in interface RootExec

Returns:

Whether or not additional batches of work are necessary. False means that this fragment is done.

dumpBatches

public void dumpBatches(Throwable t)

Deprecated.

Description copied from interface: RootExec

Dump failed batches' state preceded by its parent's state to logs. Invoked when there is a failure during fragment execution.

Specified by:

dumpBatches in interface RootExec

Parameters:

t - the exception thrown by an operator and which therefore records, in its stack trace, which operators were active on the stack

close

public void close()
           throws Exception

Deprecated.

Specified by:

close in interface AutoCloseable

Throws:

Exception

receivingFragmentFinished

public void receivingFragmentFinished(ExecProtos.FragmentHandle handle)

Deprecated.

Description copied from interface: RootExec

Inform sender that receiving fragment is finished and doesn't need any more data. This can be called multiple times (once for each downstream receiver). If all receivers are finished then a subsequent call to RootExec.next() will return false.

Specified by:

receivingFragmentFinished in interface RootExec

Parameters:

handle - The handle pointing to the downstream receiver that does not need anymore data.

iterator

public Iterator<ValueVector> iterator()

Deprecated.

Specified by:

iterator in interface Iterable<ValueVector>

getRecordCount

public int getRecordCount()

Deprecated.

getIncoming

public RecordBatch getIncoming()

Deprecated.
