Public methods
getAvailableBlocks
public int getAvailableBlocks ()
This method was deprecated
in API level 18.
Use getAvailableBlocksLong()
instead.
Returns | |
---|---|
int |
getAvailableBlocksLong
public long getAvailableBlocksLong ()
The number of blocks that are free on the file system and available to
applications. This corresponds to the Unix statvfs.f_bavail
field.
Returns | |
---|---|
long |
getAvailableBytes
public long getAvailableBytes ()
The number of bytes that are free on the file system and available to applications.
Returns | |
---|---|
long |
getBlockCount
public int getBlockCount ()
This method was deprecated
in API level 18.
Use getBlockCountLong()
instead.
Returns | |
---|---|
int |
getBlockCountLong
public long getBlockCountLong ()
The total number of blocks on the file system. This corresponds to the
Unix statvfs.f_blocks
field.
Returns | |
---|---|
long |
getBlockSize
public int getBlockSize ()
This method was deprecated
in API level 18.
Use getBlockSizeLong()
instead.
Returns | |
---|---|
int |
getBlockSizeLong
public long getBlockSizeLong ()
The size, in bytes, of a block on the file system. This corresponds to
the Unix statvfs.f_frsize
field.
Returns | |
---|---|
long |
getFreeBlocks
public int getFreeBlocks ()
This method was deprecated
in API level 18.
Use getFreeBlocksLong()
instead.
Returns | |
---|---|
int |
getFreeBlocksLong
public long getFreeBlocksLong ()
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 statvfs.f_bfree
field. Most applications
will want to use getAvailableBlocksLong()
instead.
Returns | |
---|---|
long |
getFreeBytes
public long getFreeBytes ()
The number of bytes that are free on the file system, including reserved
blocks (that are not available to normal applications). Most applications
will want to use getAvailableBytes()
instead.
Returns | |
---|---|
long |
getTotalBytes
public long getTotalBytes ()
The total number of bytes supported by the file system.
Returns | |
---|---|
long |
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.
Parameters | |
---|---|
path |
String |
Throws | |
---|---|
IllegalArgumentException |
