A question on File access
I have a program in C for Unix. I need a windows version of the program so I am writing it in Java.
Essentially what the program does is it takes in apath as command line input and reads every file in the path into a buffer. But there are a few things to take care of:
1) If there is a directory in the specified path then I should go ahead and read every file in that directory too (hence you can see this is a recursive operation)
2) if a file or a directory is a short cut, I want to make sure the file and directory is processed only once.
3) I need the logical and physical size of the file before reading the file.
The C program makes use of thestat() system call to get various statistics of the file such as: mode, inode number, number of links to the file, file size, atime, mtime, ctime, blocks...
mode: tells me if it is a directory, file or a symbolic link.
If it is a file, read it in a buffer.
If it is a directory, go ahead and do a stat() on every file in it.
if it is a symbolic link, do nothing.
inode number: If there is one file which is a hardlink to another, these two will have the same inode number. But I want to make sure I have read in the file only once. Thats where I make use of this inode number.
Other stats that I make use of is:
size: file size.
blocks: number of blocks occupied by the file (similar to size on disk)
Is there anything like stat() in Java, that I can use to get all this information of a file ?
Thanks !
