getRequiredFields

public RowMetaInterface getRequiredFields(VariableSpace space)
                                   throws KettleException
Description copied from class: BaseStepMeta
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

Parameters:
schemaName - the schemaName to set

setLoadAction

public void setLoadAction(String action)

getLoadAction

public String getLoadAction()

getDelimiter

public String getDelimiter()

getEnclosure

public String getEnclosure()

getDbNameOverride

public String getDbNameOverride()

setDbNameOverride

public void setDbNameOverride(String dbNameOverride)

setDelimiter

public void setDelimiter(String delimiter)

setEnclosure

public void setEnclosure(String enclosure)

getMissingDatabaseConnectionInformationMessage

public String getMissingDatabaseConnectionInformationMessage()
Description copied from interface: ProvidesDatabaseConnectionInformation
Provides a way for this object to return a custom message when database connection information is incomplete or missing. If this returns null a default message will be displayed for missing information.

Specified by:
getMissingDatabaseConnectionInformationMessage in interface ProvidesDatabaseConnectionInformation
Returns:
A friendly message that describes that database connection information is missing and, potentially, why.
