\class BFile
|
|
\brief BFile is a wrapper class for common operations on files providing
|
|
access to the file's content data and its attributes.
|
|
|
|
A BFile represents a file in some file system. It implements the
|
|
BPositionIO interface and thus the methods to read from and write to the
|
|
file, and is derived of BNode to provide access to the file's attributes.
