Method Detail

reset

public void reset()
Overrides:
reset in class RelationalNode

nextBatchDirect

public TupleBatch nextBatchDirect()
                           throws BlockedException,
                                  MetaMatrixComponentException,
                                  MetaMatrixProcessingException

Specified by:
nextBatchDirect in class RelationalNode
Returns:
Throws:

MetaMatrixComponentException
MetaMatrixProcessingException - if exception related to user input occured

getNodeString

protected void getNodeString(java.lang.StringBuffer str)
Overrides:
getNodeString in class RelationalNode

clone

public java.lang.Object clone()
Description copied from class: RelationalNode
All the implementation of Cloneable interface need to implement clone() method. The plan is only clonable in the pre-execution stage, not the execution state (things like program state, result sets, etc). It's only safe to call that method in between query processings, in other words, it's only safe to call clone() on a plan after nextTuple() returns null, meaning the plan has finished processing.

Specified by:
clone in class RelationalNode

getDescriptionProperties

public java.util.Map getDescriptionProperties()
Description copied from interface: Describable
Get a description as a set of properties of primitive types such as String, Integer, etc.

Specified by:
getDescriptionProperties in interface Describable
Overrides:
getDescriptionProperties in class RelationalNode
Returns:
Map of properties

setDoBatching

public void setDoBatching(boolean doBatching)

setDoBulkInsert

public void setDoBulkInsert(boolean doBulkInsert)

isTempGroupInsert

public boolean isTempGroupInsert()

close

public void close()
           throws MetaMatrixComponentException
Overrides:
close in class RelationalNode
Throws:
MetaMatrixComponentException
