Method Details

processRow

public boolean processRow(StepMetaInterface smi,
 StepDataInterface sdi)
                   throws org.pentaho.di.core.exception.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:

org.pentaho.di.core.exception.KettleException
