Method Detail

getLookupStatement

public String getLookupStatement(org.pentaho.di.core.row.RowMetaInterface rowMeta)
                          throws org.pentaho.di.core.exception.KettleDatabaseException

Throws:

org.pentaho.di.core.exception.KettleDatabaseException

getUpdateStatement

public String getUpdateStatement(org.pentaho.di.core.row.RowMetaInterface rowMeta)
                          throws org.pentaho.di.core.exception.KettleDatabaseException

Throws:

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

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

dispose

public void dispose(StepMetaInterface smi,
                    StepDataInterface sdi)

Description copied from interface: StepInterface

Dispose of this step: close files, empty logs, etc.

Specified by:

dispose in interface StepInterface

Overrides:

dispose in class BaseStep

Parameters:

smi - The metadata to work with

sdi - The data to dispose of
