JobEntryEval

public JobEntryEval()

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<org.pentaho.di.core.database.DatabaseMeta> databases,
           List<SlaveServer> slaveServers,
           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

setScript

public void setScript(String s)

getScript

public String getScript()

evaluate

public boolean evaluate(org.pentaho.di.core.Result result,
               Job parentJob,
               org.pentaho.di.core.Result prev_result)

Evaluate the result of the execution of previous job entry.

Parameters:

result - The result to evaulate.

prev_result - the previous result

parentJob - the parent job

Returns:

The boolean result of the evaluation script.

execute

public org.pentaho.di.core.Result execute(org.pentaho.di.core.Result prev_result,
                                 int nr)

Execute this job entry and return the result. In this case it means, just set the result boolean in the Result class.

Specified by:

execute in interface JobEntryInterface

Parameters:

prev_result - The result of the previous execution

nr - the number of rows

Returns:

The Result of the execution.

resetErrorsBeforeExecution

public boolean resetErrorsBeforeExecution()

Description copied from class: JobEntryBase

Checks whether a reset of the number of errors is required before execution.

Specified by:

resetErrorsBeforeExecution in interface JobEntryInterface

Overrides:

resetErrorsBeforeExecution in class JobEntryBase

Returns:

true if a reset of the number of errors is required before execution, false otherwise

evaluates

Specified by:

evaluates in interface JobEntryInterface

Overrides:

Returns:

false

isUnconditional

public boolean isUnconditional()

Description copied from class: JobEntryBase

Overrides:

isUnconditional in class JobEntryBase

Returns:

true
