    public StatFs(String path)

    Construct a new StatFs for looking at the stats of the filesystem at path. Upon construction, the stat of the file system will be performed, and the values retrieved available from the methods on this class.

    Parameters:

    path - path in the desired file system to stat.

• Method Detail

  • restat

    public void restat(String path)

    Perform a restat of the file system referenced by this object. This is the same as re-constructing the object with the same file system path, and the new stat values are available upon return.

  • getBlockSize

    public int getBlockSize()

    The size, in bytes, of a block on the file system. This corresponds to the Unix statfs.f_bsize field.

  • getBlockCount

    public int getBlockCount()

    The total number of blocks on the file system. This corresponds to the Unix statfs.f_blocks field.

  • getFreeBlocks

    public int getFreeBlocks()

    The total number of blocks that are free on the file system, including reserved blocks (that are not available to normal applications). This corresponds to the Unix statfs.f_bfree field. Most applications will want to use getAvailableBlocks() instead.

  • getAvailableBlocks

    public int getAvailableBlocks()

    The number of blocks that are free on the file system and available to applications. This corresponds to the Unix statfs.f_bavail field.
