Constructor Detail

MappingOutput

public MappingOutput(StepMeta stepMeta,
                     StepDataInterface stepDataInterface,
                     int copyNr,
                     TransMeta transMeta,
                     Trans trans)
Method Detail

processRow

public boolean processRow(StepMetaInterface smi,
                          StepDataInterface sdi)
                   throws KettleException
Description copied from interface: StepInterface
Perform the equivalent of processing one row. Typically this means reading a row from input (getRow()) and passing a row to output (putRow)).

Specified by:
processRow in interface StepInterface
Overrides:
processRow in class BaseStep
Parameters:
smi - The steps metadata to work with
sdi - The steps temporary working data to work with (database connections, result sets, caches, temporary variables, etc.)
Returns:
false if no more rows can be processed or an error occurred.
Throws:
KettleException

init

public boolean init(StepMetaInterface smi,
                    StepDataInterface sdi)
Description copied from interface: StepInterface
Initialize and do work where other steps need to wait for...

Specified by:
init in interface StepInterface
Overrides:
init in class BaseStep
Parameters:
smi - The metadata to work with
sdi - The data to initialize

setConnectorSteps

public void setConnectorSteps(StepInterface[] targetSteps,
                              List<MappingValueRename> inputValueRenames,
                              List<MappingValueRename> outputValueRenames)
