StatFs

public class StatFs
extends Object

java.lang.Object
   ↳ android.os.StatFs


Retrieve overall information about the space on a filesystem. This is a wrapper for Unix statvfs().

Summary

Public constructors

StatFs(String path)

Construct a new StatFs for looking at the stats of the filesystem at path.

Public methods

int getAvailableBlocks()

This method is deprecated. Use getAvailableBlocksLong() instead.

long getAvailableBlocksLong()

The number of blocks that are free on the file system and available to applications.

long getAvailableBytes()

The number of bytes that are free on the file system and available to applications.

int getBlockCount()

This method is deprecated. Use getBlockCountLong() instead.

long getBlockCountLong()

The total number of blocks on the file system.

int getBlockSize()

This method is deprecated. Use getBlockSizeLong() instead.

long getBlockSizeLong()

The size, in bytes, of a block on the file system.

int getFreeBlocks()

This method is deprecated. Use getFreeBlocksLong() instead.

long getFreeBlocksLong()

The total number of blocks that are free on the file system, including reserved blocks (that are not available to normal applications).

long getFreeBytes()

The number of bytes that are free on the file system, including reserved blocks (that are not available to normal applications).

long getTotalBytes()

The total number of bytes supported by the file system.

void restat(String path)

Perform a restat of the file system referenced by this object.

Inherited methods

Public constructors

StatFs

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 String: path in the desired file system to stat.

Throws
IllegalArgumentException if the file system access fails

Public methods

getAvailableBlocks

public int getAvailableBlocks ()

This method is deprecated.
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 is deprecated.
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 is deprecated.
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 is deprecated.
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 getAvailableBlocks() 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 if the file system access fails
