read file( path a[, encoding b] )
|
Group |
Reads in file a with encoding b.
The maximum file size is 4 MB. Trying to read in bigger files will lead to an error. Note: Setting system property -Dhub.datawizard.filter.readFileMaxLength=512 (in ./bin/hub.bat for Windows and ./bin/execute.sh for Linux/Unix) allows you to increase the maximum size (here to 512 MB).
The data being read is cached. Subsequent calls of this function will use the data from there to prevent performance loss.
