filename: Base filename of output files.
options: Dictionary of keyword arguments passed to customized writing routine.
overwrite: If True existing output files will be overwritten.
read: Reader object for reading output files.
verbosity: Verbosity of the writer.
zfill: Zero padding of numbered files names.

`checkdatadir`([datadir, createdir])	Function checks if data directory exists and creates it if necessary.
`write`(owner, i, forceoverwrite[, filename])	Writes output to file
`writedump`(frame[, filename])	Writes the `Frame` to dump file

Methods Documentation

checkdatadir(datadir=None, createdir=False)[source]

Function checks if data directory exists and creates it if necessary.

Parameters:

datadir (string or None, optinal, default : None) – Data directory to be checked. If None it assumes the data directory of the parent writer.
createdir (boolen, optional, default : False) – If True function creates data directory if it does not exist.

Returns:

datadirexists – True if directory exists, False if not

Return type:

boolean

write(owner, i, forceoverwrite, filename=None)[source]

Writes output to file

Parameters:

owner (Frame) – Parent Frame object
i (int) – Number of output
forceoverwrite (boolean) – If True it will forces and overwrite of the file if it exists independent of the writer attribute
filename (string) – If this is not “” the writer will use this filename instead of the standard scheme

writedump(frame, filename=None)[source]

Writes the Frame to dump file

frame (object) – object to be written to file
filename (str, optional, default : "") – path to file to be written if not set, filename will be <writer.datadir>/frame.dmp.
