Method name Description
__construct Constructor
__destruct Destructor
open Open a stream with some lazy loading smarts
close Attempt to close a file handle Will return false if it failed and true on success Note: if the file is not open the system will return true Note: this function destroys the file handle as well
eof Work out if we're at the end of the file for a stream
filesize Retrieve the file size of the path
read Read a file Handles user space streams appropriately otherwise any read will return 8192
seek Seek the file Note: the return value is different to that of fseek
write File write Note: Whilst this function accepts a reference, the underlying fwrite will do a copy! This will roughly double the memory allocation for any write you do. Specifying chunked will get around this by only writing in specific chunk sizes. This defaults to 8192 which is a sane number to use most of the time (change the default with JStream::set('chunksize', newsize);) Note: This doesn't support gzip/bzip2 writing like reading does
chmod chmod wrapper
