JobEntryTrans

public JobEntryTrans(String name)

JobEntryTrans

public JobEntryTrans()

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

setFileName

public void setFileName(String n)

getFileName

public String getFileName()

Deprecated. use getFilename() instead

Returns:

the 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

setTransname

public void setTransname(String transname)

getTransname

public String getTransname()

getDirectory

public String getDirectory()

setDirectory

public void setDirectory(String directory)

getLogFilename

public String getLogFilename()

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:

Returns:

the xml representation of the job entry
