What is the purpose of the MutableData NFS emulation fetch() and how does it differ from open()?
EDIT: I’ve partly answered my own question…
fetch()
gets an NFS file object if it exists, while create()
is used to get one for a new file.
After that, you can use open()
etc.
So my remaining question is can fetch()
be used and then allow access to file metadata?

@happybeing, so as you’ve seen. fetch
simply returns the File
object. whereas open
can be used to open and modify a file (using the openMode argument):
CONSTANTS.NFS_FILE_MODE_OVERWRITE: Replaces the entire content of the file when writing data.
CONSTANTS.NFS_FILE_MODE_APPEND: Appends to existing data in the file.
CONSTANTS.NFS_FILE_MODE_READ: Open file to read.
can fetch()
be used and then allow access to file metadata?
Yup, so fetch()
should return a File
object: Home - Documentation
Such that you could do:
// myfile is a previously fetched File object.
console.log( myfile.modified ); // date <myfile> was modified in UTC
