Constructor Detail

JobEntryFileExists

public JobEntryFileExists(String n)

JobEntryFileExists

public JobEntryFileExists()

Method Detail

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<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

loadRep

public void loadRep(Repository rep,
                    ObjectId id_jobentry,
                    List<DatabaseMeta> databases,
                    List<SlaveServer> slaveServers)
             throws KettleException

Description copied from class: JobEntryBase

This method is called by PDI whenever a job entry needs to read its configuration from a PDI repository. For JobEntryBase, this method performs no operations.

Specified by:

loadRep in interface JobEntryInterface

Overrides:

loadRep in class JobEntryBase

Parameters:

rep - the repository object

id_jobentry - the id of the job entry

databases - the list of databases

slaveServers - the list of slave servers

Throws:

KettleException - if any errors occur during the load

saveRep

public void saveRep(Repository rep,
                    ObjectId id_job)
             throws KettleException

Description copied from class: JobEntryBase

This method is called by PDI whenever a job entry needs to save its settings to a PDI repository. For JobEntryBase, this method performs no operations

Specified by:

saveRep in interface JobEntryInterface

Overrides:

saveRep in class JobEntryBase

Parameters:

rep - the repository object

id_job - the id_job

Throws:

KettleException - if any errors occur during the save

setFilename

public void setFilename(String filename)

getFilename

public String getFilename()

Description copied from class: JobEntryBase

Gets the filename of the job entry. For JobEntryBase, this method always returns null

Specified by:

getFilename in interface LoggingObjectInterface

Specified by:

getFilename in interface JobEntryInterface

Overrides:

getFilename in class JobEntryBase

Returns:

null

See Also:

LoggingObjectInterface.getFilename()

getRealFilename

public String getRealFilename()

Description copied from class: JobEntryBase

Gets the real filename of the job entry, by substituting any environment variables present in the filename. For JobEntryBase, this method always returns null

Specified by:

getRealFilename in interface JobEntryInterface

Overrides:

getRealFilename in class JobEntryBase

Returns:

null

execute

public Result execute(Result previousResult,
                      int nr)

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:

previousResult - the previous result

nr - the number of rows

Returns:

the Result object from execution of this job entry

evaluates

public boolean evaluates()

Description copied from class: JobEntryBase

This method must return true if the job entry supports the true/false outgoing hops. For JobEntryBase, this method always returns false

Specified by:

evaluates in interface JobEntryInterface

Overrides:

evaluates in class JobEntryBase

Returns:

false

getResourceDependencies

public List<ResourceReference> getResourceDependencies(JobMeta jobMeta)

Description copied from class: JobEntryBase

Gets a list of all the resource dependencies that the step is depending on. In JobEntryBase, this method returns an empty resource dependency list.

Specified by:

getResourceDependencies in interface JobEntryInterface

Overrides:

getResourceDependencies in class JobEntryBase

Returns:

an empty list of ResourceReferences

See Also:

ResourceReference

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

exportResources

public String exportResources(VariableSpace space,
                              Map<String,ResourceDefinition> definitions,
                              ResourceNamingInterface resourceNamingInterface,
                              Repository repository)
                       throws KettleException

Since the exported job that runs this will reside in a ZIP file, we can't reference files relatively. So what this does is turn the name of files into absolute paths OR it simply includes the resource in the ZIP file. For now, we'll simply turn it into an absolute path and pray that the file is on a shared drive or something like that. TODO: create options to configure this behavior

Specified by:

exportResources in interface JobEntryInterface

Overrides:

exportResources in class JobEntryBase

Parameters:

space - The variable space to resolve (environment) variables with.

definitions - The map containing the filenames and content

resourceNamingInterface - The resource naming interface allows the object to be named appropriately

repository - The repository to load resources from

Returns:

The filename for this object. (also contained in the definitions map)

Throws:

KettleException - in case something goes wrong during the export
