方法详细资料

clone

public Object clone()

从类复制的说明: 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.

指定者:

clone 在接口中 JobEntryInterface

覆盖:

clone 在类中 JobEntryBase

返回:

a clone of the object

getXML

public String getXML()

从类复制的说明: 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.

指定者:

getXML 在接口中 JobEntryInterface

覆盖:

getXML 在类中 JobEntryBase

返回:

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

从接口复制的说明: 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.

指定者:

loadXML 在接口中 JobEntryInterface

覆盖:

loadXML 在类中 JobEntryBase

参数:

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.

抛出:

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

从接口复制的说明: 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.

指定者:

loadRep 在接口中 JobEntryInterface

覆盖:

loadRep 在类中 JobEntryBase

参数:

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

抛出:

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

从接口复制的说明: 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.

指定者:

saveRep 在接口中 JobEntryInterface

覆盖:

saveRep 在类中 JobEntryBase

参数:

rep - the repository

metaStore - the MetaStore to use

id_job - the id_job

抛出:

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.

参数:

result - The result to evaulate.

prev_result - the previous result

parentJob - the parent job

返回:

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.

指定者:

execute 在接口中 JobEntryInterface

参数:

prev_result - The result of the previous execution

nr - the number of rows

返回:

The Result of the execution.

resetErrorsBeforeExecution

public boolean resetErrorsBeforeExecution()

从类复制的说明: JobEntryBase

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

指定者:

resetErrorsBeforeExecution 在接口中 JobEntryInterface

覆盖:

resetErrorsBeforeExecution 在类中 JobEntryBase

返回:

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

evaluates

public boolean evaluates()

从类复制的说明: JobEntryBase

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

从类复制的说明: JobEntryBase

Allows JobEntry objects to check themselves for consistency

指定者:

check 在接口中 JobEntryInterface

覆盖:

check 在类中 JobEntryBase

参数:

remarks - List of CheckResult objects indicating consistency status
