Method Details

checkInputFiles

public static <D> void checkInputFiles(MessageReceiver<SimpleMessage<D>> msg,
 File[] dirs,
 File... files)

Checks whether all input files/directories required by an application do exist. The non-dir files checked are naturally always input data, the dirs checked are normally places where to create new output files.

Type Parameters:

D - type of the document identifiers.

Parameters:

msg - message receiver for error messages.

dirs - array of directories to check for existance.

files - array of files to check for existance.

checkOutputFiles

public static <D> void checkOutputFiles(MessageReceiver<SimpleMessage<D>> msg,
 File... files)

Checks whether all simple output files of an application do NOT YET exist. Since normally an application does not replace existing directories by new simple files automatically, such pre-existance yields an ERROR, while that of a simple file yields only a warning.

Type Parameters:

D - type of the document identifiers.

Parameters:

msg - message receiver for error messages.

files - array of files to check for non-existance.
