Constructor Detail

Abort

public Abort(StepMeta stepMeta,
             StepDataInterface stepDataInterface,
             int copyNr,
             TransMeta transMeta,
             Trans trans)

Method Detail

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

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
