Method Detail

reset

public void reset()

Overrides:

reset in class SubqueryAwareRelationalNode

closeDirect

public void closeDirect()

Overrides:

closeDirect in class SubqueryAwareRelationalNode

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

init

public void init()

This state can be determined prior to initialize and is the same for all nodes, so it is moved into it's own init routine

nextBatchDirect

protected TupleBatch nextBatchDirect()
                              throws BlockedException,
                                     TeiidComponentException,
                                     TeiidProcessingException

Description copied from class: RelationalNode

Template method for subclasses to implement.

Specified by:

nextBatchDirect in class RelationalNode

Returns:

Throws:

BlockedException

TeiidComponentException

TeiidProcessingException - if exception related to user input occured

initialize

public void initialize(CommandContext context,
                       BufferManager bufferManager,
                       ProcessorDataManager dataMgr)

Overrides:

initialize in class RelationalNode
