Returns:

the file name, empty if not known

getFileNameOrThrow

public String getFileNameOrThrow()

Gets the file name of the source.

Most sources originate from a file-based location. This is captured and returned here where available.

Returns:

the file name

Throws:

IllegalArgumentException - if the file name is not known
