Constructor Detail

JobEntryFileCompare

public JobEntryFileCompare(String n)

JobEntryFileCompare

public JobEntryFileCompare()
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

getRealFilename1

public String getRealFilename1()

getRealFilename2

public String getRealFilename2()

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

setFilename1

public void setFilename1(String filename)

getFilename1

public String getFilename1()

setFilename2

public void setFilename2(String filename)

getFilename2

public String getFilename2()

isAddFilenameToResult

public boolean isAddFilenameToResult()

setAddFilenameToResult

public void setAddFilenameToResult(boolean addFilenameToResult)

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
