Method Detail

execute

public Result execute(Result prev_result,
                      int nr)
               throws KettleException

Description copied from interface: JobEntryInterface

Execute the job entry. The previous result and number of rows are provided to the method for the purpose of chaining job entries, transformations, etc.

Specified by:

execute in interface JobEntryInterface

Parameters:

prev_result - the previous result

nr - the number of rows

Returns:

the Result object from execution of this job entry

Throws:

KettleException - if any Kettle exceptions occur

loadXML

public void loadXML(Node entrynode,
                    List<DatabaseMeta> databases,
                    List<SlaveServer> slaveServers,
                    Repository rep)
             throws KettleXMLException

Description copied from interface: JobEntryInterface

This method is called by PDI whenever a job entry needs to read its settings from XML. The XML node containing the job entry�s settings is passed in as an argument. Again, the helper class org.pentaho.di.core.xml.XMLHandler is typically used to conveniently read the settings from the XML node.

Specified by:

loadXML in interface JobEntryInterface

Parameters:

entrynode - the top-level XML node

databases - the list of databases

slaveServers - the list of slave servers

rep - the repository object

Throws:

KettleXMLException - if any errors occur during the loading of the XML

check

public void check(List<CheckResultInterface> remarks,
                  JobMeta jobMeta)

Description copied from class: JobEntryBase

Support for overrides not having to put in a check method. For JobEntryBase, this method performs no operations.

Specified by:

check in interface JobEntryInterface

Overrides:

check in class JobEntryBase

Parameters:

remarks - CheckResults from checking the job entry

jobMeta - JobMeta information letting threading back to the JobMeta possible
