stepMeta - The stepMeta to help checking

prev - The fields coming from the previous step

input - The input step names

output - The output step names

info - The fields that are used as information by the step

getQuotedSchemaTableName

public String getQuotedSchemaTableName(VariableSpace space)
                                throws KettleException

Parameters:

space - the variableSpace to be used.

Returns:

the quoted and resolved schema table name.

Throws:

KettleException - if no table specified.

connectToDatabase

public Database connectToDatabase()
                           throws KettleException

Returns:

the database.

Throws:

KettleException - if an error occurs.

getStep

public StepInterface getStep(StepMeta stepMeta,
                             StepDataInterface stepDataInterface,
                             int cnr,
                             TransMeta transMeta,
                             Trans disp)

Get the executing step, needed by Trans to launch a step.

Parameters:

stepMeta - The step info

stepDataInterface - the step data interface linked to this step. Here the step can store temporary data, database connections, etc.

cnr - The copy nr to get

transMeta - The transformation info

disp - The launching transformation

See Also:

StepMetaInterface.getStep(org.pentaho.di.trans.step.StepMeta, org.pentaho.di.trans.step.StepDataInterface, int, org.pentaho.di.trans.TransMeta, org.pentaho.di.trans.Trans)

getStepData

public StepDataInterface getStepData()

Get a new instance of the appropriate data class. This data class implements the StepDataInterface. It basically contains the persisting data that needs to live on, even if a worker thread is terminated.

Specified by:

getStepData in interface StepMetaInterface

Overrides:

getStepData in class AbstractStepMeta

Returns:

The appropriate StepDataInterface class.

See Also:

StepMetaInterface.getStepData()

setDefault

public void setDefault()

Set default values

See Also:

StepMetaInterface.setDefault()

getFields

public void getFields(RowMetaInterface inputRowMeta,
                      String name,
                      RowMetaInterface[] info,
                      StepMeta nextStep,
                      VariableSpace space)
               throws KettleStepException

Get the fields that are emitted by this step

Specified by:

getFields in interface StepMetaInterface

Overrides:

getFields in class BaseStepMeta

Parameters:

inputRowMeta - The fields that are entering the step. These are changed to reflect the output metadata.

name - The name of the step to be used as origin

info - The input rows metadata that enters the step through the specified channels in the same order as in method getInfoSteps(). The step metadata can then choose what to do with it: ignore it or not. Interesting is also that in case of database lookups, the layout of the target database table is put in info[0]

nextStep - if this is a non-null value, it's the next step in the transformation. The one who's asking, the step where the data is targetted towards.

space - TODO

Throws:

KettleStepException - when an error occurred searching for the fields.

See Also:

BaseStepMeta.getFields(org.pentaho.di.core.row.RowMetaInterface, java.lang.String, org.pentaho.di.core.row.RowMetaInterface[], org.pentaho.di.trans.step.StepMeta, org.pentaho.di.core.variables.VariableSpace)

getRequiredFields

public RowMetaInterface getRequiredFields(VariableSpace space)
                                   throws KettleException

The natural way of data flow in a transformation is source-to-target. However, this makes mapping to target tables difficult to do. To help out here, we supply information to the transformation meta-data model about which fields are required for a step. This allows us to automate certain tasks like the mapping to pre-defined tables. The Table Output step in this case will output the fields in the target table using this method. This default implementation returns an empty row meaning that no fields are required for this step to operate.

Specified by:

getRequiredFields in interface StepMetaInterface

Overrides:

getRequiredFields in class BaseStepMeta

Parameters:

space - the variable space to use to do variable substitution.

Returns:

the required fields for this steps meta data.

Throws:

KettleException - in case the required fields can't be determined

BaseStepMeta.getRequiredFields(org.pentaho.di.core.variables.VariableSpace)
