      • allocate

        public void allocate​(int nrFields)

      • clone

        public Object clone()
        Description copied from class: JobEntryBase
        This method is called when a job entry is duplicated in Spoon. It needs to return a deep copy of this job entry object. It is essential that the implementing class creates proper deep copies if the job entry configuration is stored in modifiable objects, such as lists or custom helper objects.
        Specified by:
        clone in interface JobEntryInterface
        Overrides:
        clone in class JobEntryBase
        Returns:
        a clone of the object

      • getXML

        public String getXML()
        Description copied from class: JobEntryBase
        This method is called by PDI whenever a job entry needs to serialize its settings to XML. It is called when saving a job in Spoon. The method returns an XML string, containing the serialized settings. The string contains a series of XML tags, typically one tag per setting. The helper class org.pentaho.di.core.xml.XMLHandler is typically used to construct the XML string.
        Specified by:
        getXML in interface JobEntryInterface
        Overrides:
        getXML in class JobEntryBase
        Returns:
        the xml representation of the job entry

      • loadXML

        public void loadXML​(Node entrynode,
                    List<org.pentaho.di.core.database.DatabaseMeta> databases,

                    Repository rep,
                    org.pentaho.metastore.api.IMetaStore metaStore)
             throws org.pentaho.di.core.exception.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
        Overrides:
        loadXML in class JobEntryBase
        Parameters:
        entrynode - the top-level XML node
        databases - the list of databases
        slaveServers - the list of slave servers
        rep - the repository object
        metaStore - The metaStore to optionally load from.
        Throws:
        org.pentaho.di.core.exception.KettleXMLException - if any errors occur during the loading of the XML

      • loadRep

        public void loadRep​(Repository rep,
                    org.pentaho.metastore.api.IMetaStore metaStore,
                    org.pentaho.di.repository.ObjectId id_jobentry,
                    List<org.pentaho.di.core.database.DatabaseMeta> databases,
                    List<SlaveServer> slaveServers)
             throws org.pentaho.di.core.exception.KettleException
        Description copied from interface: JobEntryInterface
        This method is called by PDI whenever a job entry needs to read its configuration from a PDI repository. The job entry id given in the arguments should be used as the identifier when using the repository's serialization methods.
        Specified by:
        loadRep in interface JobEntryInterface
        Overrides:
        loadRep in class JobEntryBase
        Parameters:
        rep - the repository object
        metaStore - the MetaStore to use
        id_jobentry - the id of the job entry
        databases - the list of databases
        slaveServers - the list of slave servers
        Throws:
        org.pentaho.di.core.exception.KettleException - if any errors occur during the load

      • saveRep

        public void saveRep​(Repository rep,
                    org.pentaho.metastore.api.IMetaStore metaStore,
                    org.pentaho.di.repository.ObjectId id_job)
             throws org.pentaho.di.core.exception.KettleException
        Description copied from interface: JobEntryInterface
        This method is called by PDI whenever a job entry needs to save its settings to a PDI repository. The repository object passed in as the first argument provides a convenient set of methods for serializing job entry settings. When calling repository serialization methods, job id and job entry id are required. The job id is passed in to saveRep() as an argument, and the job entry id can be obtained by a call to getObjectId() inherited from the base class.
        Specified by:
        saveRep in interface JobEntryInterface
        Overrides:
        saveRep in class JobEntryBase
        Parameters:
        rep - the repository
        metaStore - the MetaStore to use
        id_job - the id_job
        Throws:
        org.pentaho.di.core.exception.KettleException - if any errors occur during the save
