#flatten

Constructor Details

#initialize(pathname) ⇒ FileWriter

Create a file writer instance. Files are written by opening, adding a log message and closing again, to provide reliability. For this reason, this is a Hoodoo::Logger::SlowWriter subclass.

If you want faster file access at the expense of immediate updates / reliability due to buffering, open a file externally to create an I/O stream and pass this persistently-open file’s stream to an Hoodoo::Logger::StreamWriter class instead.

pathname

Full pathname of a file that can be opened in “ab” (append for writing at end-of-file) mode.
