Method Detail

nameResource

String nameResource(String prefix,
                    String originalFilePath,
                    String extension,
                    ResourceNamingInterface.FileNamingType namingType)

Create a (file) name for a resource based on a prefix and an extension.

Parameters:

prefix - The prefix, usually the name of the object that is being exported

originalFilePath - The original path to the file. This will be used in the naming of the resource to ensure that the same GUID will be returned for the same file.

extension - The extension of the filename to be created. For now this also gives a clue as to what kind of data is being exported and named..

namingType - the file naming type to use, in case of DATA_FILE for example, the return value might not be the complete file, but rather

Returns:

The filename, typically including a GUID, but always the same when given the same prefix and extension as input.

nameResource

String nameResource(org.apache.commons.vfs2.FileObject fileObject,
                    org.pentaho.di.core.variables.VariableSpace space,
                    boolean pathOnly)
             throws org.apache.commons.vfs2.FileSystemException

Create a (file) name based on the passed FileObject

Parameters:

FileObject - fileObject The file in which the name ....

VariableSpace - variable(space) of the transformation or job.

pathOnly - Set to true to just return the path, false to return file name and path

Returns:

String The file name with the path set as a variable. If pathOnly is set to true then the file name will be left out.

Throws:

org.apache.commons.vfs2.FileSystemException

getDirectoryMap

Map<String,String> getDirectoryMap()

Returns:

the map of folders mapped to created parameters during the resource naming.
