rossi.fstools.fs.reiserfs
Class StatDataItem

java.lang.Object
  rossi.fstools.fs.reiserfs.Item
      rossi.fstools.fs.reiserfs.StatDataItem

All Implemented Interfaces:

Inode

Direct Known Subclasses:

StatDataV1, StatDataV2

public abstract class StatDataItem

extends Item

implements Inode

StatDataItem holds statistics about the object it describes. It is a close analogy to the Inodes in other filesystems except it doesnt directly hold block pointers.

Constructor Detail

StatDataItem

public StatDataItem(byte[] buffer,
                    int bufferOffset,
                    LeafNode block,
                    ItemHead header)
             throws FsException

Method Detail

getMode

public abstract int getMode()

Description copied from interface: Inode

Get the mode of the object. The least significant 12 bits control the object's access permissions. The next 4 bits control the type of the object.

Specified by:

getMode in interface Inode

Returns:

the mode

setMode

public abstract void setMode(int aMode)

Description copied from interface: Inode

Set the mode.

Specified by:

setMode in interface Inode

Parameters:

aMode - the mode.

See Also:

Inode.getMode()

getNumLinks

public abstract long getNumLinks()

Description copied from interface: Inode

Get the number of hard links to this file. A value of zero indicates that the object is deleted. A hard link is a directory entry pointing directly at this object (not via symlinks).

Specified by:

getNumLinks in interface Inode

Returns:

the number of links

setNumLinks

public abstract void setNumLinks(long aNumLinks)

Specified by:

setNumLinks in interface Inode

getUserId

public abstract long getUserId()

Description copied from interface: Inode

Get the user id of the object's owner.

Specified by:

getUserId in interface Inode

Returns:

the user id

setUserId

public abstract void setUserId(long aUserId)

Specified by:

setUserId in interface Inode

getGroupId

public abstract long getGroupId()

Description copied from interface: Inode

Get the group id of the object's owner.

Specified by:

getGroupId in interface Inode

Returns:

the group id

setGroupId

public abstract void setGroupId(long aGroupId)

Specified by:

setGroupId in interface Inode

getSize

public abstract long getSize()

Description copied from interface: Inode

Get the size of the data associated with the object. This is mostly meaningful with normal files.

Specified by:

getSize in interface Inode

Returns:

the size

setSize

public abstract void setSize(long aSize)

Specified by:

setSize in interface Inode

getAccessTime

public abstract long getAccessTime()

Description copied from interface: Inode

Get the time the data was last accessed.

Specified by:

getAccessTime in interface Inode

Returns:

the access time.

setAccessTime

public abstract void setAccessTime(long aAccessTime)

Specified by:

setAccessTime in interface Inode

getModifyTime

public abstract long getModifyTime()

Description copied from interface: Inode

Get the time the data was last modified.

Specified by:

getModifyTime in interface Inode

Returns:

the access time.

setModifyTime

public abstract void setModifyTime(long aModifyTime)

Specified by:

setModifyTime in interface Inode

getChangedTime

public abstract long getChangedTime()

Description copied from interface: Inode

Get the time this Inode metadata was last changed.

Specified by:

getChangedTime in interface Inode

Returns:

long

setChangedTime

public abstract void setChangedTime(long aChangedTime)

Specified by:

setChangedTime in interface Inode

getBlocks

public abstract long getBlocks()

setBlocks

public abstract void setBlocks(long aBlocks)

getRDev

public abstract int getRDev()

Get the device major/minor numbers.

create

public static StatDataItem create(byte[] buffer,
                                  int bufferOffset,
                                  LeafNode block,
                                  ItemHead header)
                           throws FsException

Create the appropriate subclass for a StatDataItem on disk. Figure out if its V1 or V2 based on the item size.

Parameters:

buffer - a byte[] buffer holding the item

bufferOffset - a int offset into the buffer marking the start of the item

block - the LeafNode containing this item

header - the ItemHead for this item

Returns:

StatDataItem

Throws:

FsException

toString

public java.lang.String toString()
